Anyone who prioritizes physical well-being during long hours of sitting: office professionals preventing desk-related strain, people managing existing spinal discomfort, and gamers who need adaptive support for long sessions.

A dynamic chair acts as a responsive partner to your body rather than a static object. Standard chairs lock you into one fixed position; the LiberNovo Omni moves with you in real time. The backrest, neck support, seat, and armrests follow your posture automatically, spreading your weight to reduce pressure points and fatigue.

The Bionic FlexFit Backrest links 8 flexible panels through 14 dual connection points at the front, forming one support surface, while a dual-layer spherical bracket with 16 pivot points at the back lets it contour to your spine. On the electric models, lumbar depth is set by a motorized actuator controlled from the armrest buttons: adjust how far the support extends for a custom fit, or start an OmniStretch cycle with the third button. The chair is rated for up to 300 lbs (136kg under BIFMA testing; 110kg under EN 1335).

OmniStretch is a guided back stretch. Press the button and the lumbar support runs through a programmed cycle of about five minutes, pressing gently into the lower back and releasing, so your back gets a break from holding one position. It works at any recline angle and feels deepest at 160°.

Neck support, backrest, support frame, electric lumbar actuator (electric models), armrests, seat cushion, gas lift, five-star base, casters, and an optional footrest.

Seat height, backrest recline (4 preset positions on the original LiberNovo Omni, 5 on SE, Gen, and Pro), lumbar depth (how far the support extends), recline tension, 4D armrests (height, width, angle, forward/back slide), neck support position, and an optional footrest for leg support.

All four share the same frame and the same dynamic support system.
Omni SE is the manual build: a rotary lumbar knob with 40mm of travel, no battery (so no OmniStretch), and a single finish, Obsidian. It offers 5 recline positions (105°, 115°, 125°, 135°, 160°).
The original LiberNovo Omni is the electric model that started the line, with a 50mm electric lumbar actuator, one-touch control, and 4 recline positions (105°, 120°, 135°, 160°).
Omni Gen, the upgraded generation, retains the 50mm electric lumbar adjustment while adding 5 recline positions (105°, 115°, 125°, 135°, 160°) and more adjustment flexibility.
Omni Pro also offers 5 recline positions (105°, 115°, 125°, 135°, 160°), plus Active Airflow seat ventilation, a die-cast aluminum base (vs. glass-fiber-reinforced nylon on SE, Gen, and the original), Gabriel Atlantic fabric, and a larger 3000mAh battery (vs. 2200mAh on Gen).
Choose SE if you'd rather set lumbar depth by hand with no battery to charge, the original for core electric support, Gen for the latest adjustability, and Pro for Active Airflow ventilation and premium materials.

On the electric models, by a removable battery. Pop it out and charge it via USB-C, just like a power bank. No cable is included, but any standard 5V/2A USB-C cable works.

For an average user (143 lbs / 5'7"), a full charge takes about 3.5 hours and supports roughly 41 OmniStretch cycles. A 10-minute charge gives about 2 cycles, 30 minutes gives about 6, 60 minutes gives about 12.

About a month of use, based on one OmniStretch cycle plus five lumbar adjustments per day. With only occasional adjustments, a charge can last up to a year. Taller or heavier users draw more from the motor, which can shorten this.

10 minutes gives roughly 5% charge (about 2 OmniStretch cycles). 30 minutes gives roughly 15% charge (about 6 cycles), based on a 143 lb user.

Gen uses a 2200mAh battery; Pro uses 3000mAh to support its Active Airflow fan. With ventilation off, both are rated for up to 30 days of daily use.

No. SE uses a fully manual rotary lumbar knob and doesn't require charging.

The LiberNovo Omni battery charges via a standard USB-C port and reaches 100% in about 3.5 hours. One charge lasts for about 30 days of daily OmniStretch cycles. If you’re only making occasional minor adjustments, you can go up to a year before needing to charge it again.

Frame: glass-fiber-reinforced plastic.
Neck support: hydrophilic memory foam that compresses and rebounds around the neck's natural curve.
Backrest: high-density elastic foam balancing softness and firmness.
Seat: multi-density foam with three firmness zones to disperse pressure across hips and thighs.

Mesh tends to concentrate pressure at specific points, which can cause soreness over long sessions. Layered foam disperses weight evenly for consistent comfort that doesn't fade with hours of sitting.

In most climate-controlled homes and offices, overheating isn't a concern. Foam was chosen for its support and comfort advantages over mesh. If you tend to run warm, the Omni Pro adds Active Airflow seat ventilation.

This is intentional, not a defect. The adjustable ergonomic backrest needs room for its support structure to move and adapt to your body. Pressing the foam tight against the frame would reduce adjustment range and cause premature wear.

Maxis is LiberNovo's chair for taller and larger users, developed after the LiberNovo Omni. It isn't that chair scaled up. The seat depth, backrest, armrests, neck support, and recline mechanism are all re-engineered around a wider, deeper seat and stronger, steadier support. It suits taller and heavier individuals, broad-shouldered or fitness-focused users, and anyone who sits for extended periods at a desk, gaming, or resting.

Maxis is designed for heights of 178–200cm (5'10"–6'7") and loads up to 181kg (399 lbs). Users under 178cm (5'10") can still use it, though the 52cm (20.5 in) seat depth may feel deep, so we recommend pairing it with a footrest. Above 200cm (6'7"), a good fit isn't guaranteed; check seated shoulder height, leg length, and neck support reach, and try it in person if possible. The six-spring Controlled Recline System isn't recommended for users under 40kg (88 lbs).

No. It's built to give steadier support to anyone who is taller or broader through the back and shoulders, or who simply sits for long stretches. Average-build users can use it comfortably too. If you're slimmer, shorter, or prefer a lighter seat feel, check the size chart first.

Maxis is redesigned around five body contact points rather than scaled up: a 52cm seat depth (many oversized chairs add width but not depth); a Bionic FlexFit backrest sized for broad shoulders and thicker backs; taller, wider, longer armrests with a curved profile and a locking mechanism; extended neck support travel; and a 105°-160° five-position recline paired with the six-spring Controlled Recline system.

The deeper, wider cushion gives the hips and thighs full support. Tall users with proportionally shorter legs can still use Maxis comfortably. Pair it with the StepSync footrest, a separate accessory, to keep good posture without the seat edge pressing into the thighs.

The Bionic FlexFit Backrest on Maxis is sized for taller, broader-backed users. Its width is set to wrap the back fully, and it isn't narrowed just to give the armrests more travel room.

Larger users put more demand on armrest width, length, height, and stability. Maxis armrests have 128mm of vertical travel and adjust laterally from 400–600mm, wide enough to avoid pinching. The armrest lock stops the arms from splaying outward when you lean on them to sit down or stand up, a stability feature specific to Maxis (the LiberNovo Omni prioritizes armrest flexibility instead, since the two chairs are built for different body types).

Maxis uses the Controlled Recline System: six springs engage progressively as you lean back, so support stays steady across the full recline range with no sudden drop. There are 5 preset positions: 105°/115°/125°/135°/160°. If the recline feels unstable, it's usually because the tension dial, which ships at a fairly firm factory setting, isn't matched to your body weight yet. Loosen or tighten it as needed.

A Class 4 heavy-duty gas cylinder and BIFMA X5.11 certification, the standard for large-occupant office chairs.

It depends on the model. Maxis Electric takes about 3.5 hours from low to full; Maxis Airflow takes about 4.4 hours. Use a 5V/2A charger, as specified in the manual.

No. The electric functions run on a removable battery. Charge it via USB-C when it's low; there's no need to stay plugged in for daily use.

Yes. The indicator light changes when the battery is low. If it turns red or the electric functions feel sluggish, charge before using them again.

No. They aren't interchangeable, and we don't recommend using a battery across models. Control boards and battery specs differ by version; contact support to confirm the right battery for your model.

Roughly 520mm deep, 580mm wide, and 70mm thick. It isn't simply scaled up: the support is recalibrated for larger body types and long sitting, so the seat wraps around you without excessive sinking.

Maxis Manual and Maxis Electric are softer and more enveloping. Maxis Airflow is firmer because of the reinforced structure that protects its air channels.

The front edge uses a soft-support design to reduce thigh pressure, but users with shorter legs or who sit far forward may still feel the seat is deep. Sitting back so the lower back contacts the backrest usually resolves this; a footrest helps too.

Up to 200cm. It has a wider adjustment range than the LiberNovo Omni neck support, with a higher position and more fore-aft travel.

Molded foam over the Bionic FlexFit Backrest's flexible panel structure, sized wider to fully wrap broader and thicker backs while meeting ergonomic support standards.

It's designed to run at about 40–41dB on the low setting, within a ≤42dB spec, roughly the level of a quiet office.

The footrest solves the common problem where a standard desk (usually 75cm high) doesn't quite match your height. It offers two height levels to ensure your feet have a solid base:

4.7" Height: Best for users between 158–169 cm (5'2""–5'7"").

By choosing the right level, you avoid having your feet dangle, which keeps your legs and lower back in a much more natural, comfortable position.

The footrest serves three main purposes to improve your sitting experience:

Corrects Sitting Posture: It provides a solid base for your feet so they aren't left dangling. This keeps your legs and lower back in a more natural position, making it much easier to maintain proper posture.

Relieves Leg Pressure: The footrest is slightly angled upward to keep your legs and hips better aligned, which improves circulation and reduces that heavy, tired feeling.

Dual-Level Comfort: It features a second level that extends so you can put your legs up when fully reclined. It gives you a relaxed, ""Lazyboy"" style experience when you want to take a break.

Unlike fixed, built-in footrests that are often flimsy or stuck in one spot, our independent two-level footrest adapts dynamically to how you’re sitting:

Level 1 (Ergonomic Support): Provides a stable base for your feet during long office sessions, keeping your posture aligned while you work.

Level 2 (Deep Relaxation): Allows you to kick your legs up when you want to lean back and fully relax.

Because it isn't attached to the chair frame, it provides much more stable, proactive support that stays exactly where you need it.

The Cooling Seat Pad is specifically contour-designed to pair perfectly with the LiberNovo Dynamic Ergonomic Chair. However, it is also highly versatile:

General Fit: It fits most flat-surface chairs (office, gaming, dining, etc.) as long as the seat size is at least 17.7" × 19.7".

⚠ For indoor use only; not for car seats.

No, the surface of the fabric is designed to stay completely dry. Thanks to its 3-layer design (fabric, membrane, and gel), the pad provides a gradual cooling effect. It feels comfortably cool rather than icy cold, ensuring a pleasant experience even during long sessions.

The cooling effect can feel a bit weak immediately after being kept in sealed packaging during transport. After unpacking your Cooling Seat Pad, simply place it in a cool, ventilated area for about 30 minutes to restore its natural cooling effect.

Simply place the Cooling Seat Pad in a well-ventilated area or near an A/C vent for 15–30 minutes. This allows the gel layer to release stored heat and restores its natural cooling effect.

The gel inside is designed to absorb and hold heat. After continuous use, it slowly pulls in your body heat, which eventually reduces that initial cool sensation. To refresh it, just place the Cooling Seat Pad in a ventilated area—or on a cool surface like wood or stone—for 15–30 minutes to let the heat dissipate.

No, the Cooling Seat Pad uses an advanced multi-network polymer gel. Compared to common gels found in other products, this material has a higher heat capacity and better conductivity. This means it can absorb more heat and keep you feeling cooler for a longer period.

While the Cooling Seat Pad is designed for comfort, it is not recommended for everyone. Please take note of the following guidelines:

Sensitivity: It is not recommended for pregnant women, individuals with a high sensitivity to cold, or those with sensitive skin.

Weight Limit: The pad has a maximum load capacity of 136 kg (300 lbs).

Age Restrictions: Not for use by children under 3 years old. Children using the pad must be supervised at all times.

No. The large surface area of the Cooling Seat Pad creates enough friction with the chair to keep it steady. If any slight shifting occurs over time, you can easily just slide it back into your preferred position.

Minor settling is normal after the Cooling Seat Pad has been under pressure for a long time. To help with this, the pad features a zoned design that distributes your weight evenly to minimize any changes in shape.

⚠ Do not stand, kneel, place heavy items, or apply excessive force on the Cooling Seat Pad.

Those fine surface lines are completely normal marks that form when the high-conductivity gel solidifies during the molding process. They are simply a result of the manufacturing technique and do not affect the quality or the cooling feel of the pad.

The Cooling Seat Pad uses an eco-friendly, non-toxic gel that meets RoHS safety standards. The gel is engineered to stay in a jelly-like state and is double-sealed within the pad, so it won’t leak under normal use.

Be sure to keep sharp objects away from the pad to avoid puncturing the outer layers.

If your neck support isn't adjusting, please follow these troubleshooting steps based on the issue:

Scenario 1: Horizontal (Forward/Backward) Adjustment

The Fix: You must press and hold the adjustment buttons on both sides of the headrest simultaneously to move it forward or backward.

Still Stuck? If it won't budge, please record a quick video showing you pressing the buttons while attempting to move it, and send it to us for review.

Scenario 2: Vertical (Up/Down) Adjustment

The Fix: Check the vertical rails for any obstructions or debris. Ensure the headrest is properly aligned and not tilted or caught on one side.

Still Stuck? Clear any visible blockages. If the movement remains rough or jammed, please send us a video of the rails and the sliding action so we can assist.

If the backrest on your LiberNovo Omni is difficult to recline or snaps back too forcefully, you can fine-tune the resistance using the Tension Adjustment Knob:

How to Adjust

Locate the Knob: Find the Recline Tension Adjustment Knob located underneath the right side of the seat.

Rotate Slowly: Turn the knob gradually until you reach your preferred tension level.

Test: Sit and test the recline after each adjustment until the movement feels natural.

Adjustment Guide

Too Stiff (Won't recline): Rotate the Recline Tension Adjustment Knob clockwise to increase the support force.

Too Loose (Snaps back): Rotate the Recline Tension Adjustment Knob counter-clockwise to decrease the resistance.

Important Tips
Stand up before adjusting to remove weight from the mechanism.
If the knob feels jammed or makes noise after a few turns, please send us a video for further help.

If you are unable to adjust the tension on your LiberNovo Omni, please try the following:

Check the Limit: If the knob won't turn further in one direction, it may have reached its limit. Try rotating it in the opposite direction.

Reseat the Knob: The knob may not be fully engaged. Try removing and reinserting it firmly, then attempt to adjust it again.

If the issue persists, please send us a video of the malfunction so we can provide further assistance.

If you can't change the recline angle on your LiberNovo Omni, please try these steps:

Lean Forward: You need to take your weight off the backrest to move the lever to a different setting. Lean forward so you aren't leaning against the chair, then try shifting the lever again.

Listen for the Click: The lever must be moved fully to the next position to work. Listen for a clear ""click,"" which confirms it has successfully shifted into a new setting.

Still Stuck? If it still won't budge, there might be a mechanical issue. Please record a quick video of the lever and backrest movement so we can troubleshoot this for you.

The LiberNovo Omni uses a snap-fit design to make the backrest easy to adjust, clean, or replace. If the clips have detached, simply align the backrest with the mounting points and press firmly until they snap back into place. If the problem persists or the clips won't stay secure, please contact our support team with a quick photo or video so we can resolve this for you.

This is usually related to the battery connection, battery charge level, or the USB-C charging cable.

Troubleshooting steps

Check the battery connection and charge
Remove the battery from the armrest and make sure it is fully and correctly inserted. If the battery is low, charge it for 30 minutes to 1 hour, then reinsert it and press the button again to see if the indicator light turns on.

Check the USB-C charging cable
If the light does not turn on during charging or after reinserting the battery, make sure the USB-C cable is securely plugged into the battery. If possible, try a different cable or power source to rule out a cable issue.

If the issue persists
If the problem remains after completing the steps above, there may be an issue with the battery contacts or internal circuitry. Please record a short video showing the battery, charging connection, and button operation, and send it to our support team for further assistance.

This is an intentional design feature built to provide stable, reliable arm support while preventing the mechanism from loosening over time.

Stability & Support: The armrest width adjustment is designed with higher resistance to keep your arms securely supported and prevent wobbling during use.

Long-Term Durability: This added tension ensures the adjustment mechanism remains reliable even after years of extended use.

Recommended Action: Try adjusting the armrests back and forth several times. As the internal components are used, the parts will settle in and the movement will naturally become smoother.

Further Assistance: If the adjustment still feels too stiff after repeated use, please record a short video of the movement and contact our support team.

The lubricant inside the armrest bearing is intentionally applied to ensure smooth, stable adjustment during use.

To maintain performance, please try to avoid direct contact with the exposed bearing area during adjustment. This helps prevent lubricant transfer to your hands and reduces dust buildup, ensuring the armrest continues to operate smoothly over time.

If you have any questions or concerns during use, feel free to contact our support team. We’re happy to help.

A red light indicates that the battery is low. When this happens, the control buttons are temporarily disabled. Just charge the battery and reinsert it; the buttons will then work normally again.

To adjust the armrest height, you must use the adjustment lever.

Press and hold the lever on the side of the armrest to raise or lower it. Once you release the lever, the armrest will lock into place.

If the armrest still cannot be adjusted while holding the lever, please record a short video showing the lever operation and armrest movement and send it to us via the chat window. Our support team will assist you as soon as possible.

If the armrest feels stuck in any direction, please check the following:

Inspect the guide rails
Look for visible damage, misalignment, or deformation where the armrest connects to the chair.
 
Check the mounting screws
Make sure the armrest screws are fully tightened. Loose screws can cause misalignment and jamming.
 
Clear debris from the rails
Remove any dust or debris from the guide rails. After cleaning, apply a small amount of lubricant and try adjusting again.
 
If the issue remains, please send us a short video showing the armrest movement and rail area, and our support team will assist you.

This is intentional and part of the chair’s design, not a quality issue. The backrest uses a flexible structure, and the fabric is designed to wrinkle slightly so it can better adapt to movement and shape changes as the backrest responds to your body, helping maintain consistent support. The wrinkles also reduce friction between the fabric and clothing, which helps prevent wear and extend the fabric’s lifespan. If wrinkles appear during use, simply smooth the fabric gently by hand.

If the knob keeps spinning or won't secure the footrest, there is likely an issue with the internal nut. Please follow these steps to fix it:

1. Check the Nut Status Flip the footrest over and look inside the adjustment slot on the bottom:

Missing Nut: If you don't see a metal nut inside the slot, the knob has nothing to grip. Please contact our support team and we will send you a replacement nut for free.

Misaligned Nut: If the nut is tilted or hasn't dropped into its designated slot, the knob will just spin without locking.

2. Reinstall the Nut If the nut is there but misaligned:

Use your finger or a small tool to push the nut firmly into the bottom of the slot so it sits flat and centered.

Align the adjustment knob with the nut's threads and turn it clockwise slowly until it is completely tight and the footrest is secure.

Quick Tip Perform this in a well-lit area so you can easily see the threads. If the nut is missing or the knob still won't tighten after realigning it, contact our support team and we will get the necessary parts sent out to you immediately.

First, try to identify where the noise is coming from, such as the backrest, armrests, seat, or base, and note the type of sound you hear. Check whether the noise occurs during adjustment, movement, or while sitting still, and whether it changes with body weight.

If possible, repeat the action that causes the noise and record a short video with clear audio, focusing on the area where the sound occurs. You may also check whether any screws at major connection points are loose and tighten them if needed.

If the noise continues, please send us the video so we can help identify the cause and assist further.

Because the chair is shipped as a large item, minor damage to the outer packaging can occasionally occur during transit. If you notice any damage upon delivery, please take clear photos and videos right away, including the outer box and any affected internal items.

Once you share the images with us, we’ll review them and assist with the next steps to resolve the issue as quickly as possible.

This is normal and part of the chair’s ergonomic design. The armrest and rear support rod need adjustable clearance to accommodate different positions and usage scenarios, so a visible gap is intentionally built into the structure.

This design helps prevent binding during adjustments and ensures smoother, more effective movement. It is not an assembly issue or a quality defect. Please feel free to use the chair with confidence. If you have any further questions, we’re happy to help.

A slight odor is normal with a new chair and usually comes from materials used during production, such as foam or packaging. These odors are non-toxic and safe to use.

To help the smell dissipate, place the chair in a well-ventilated area near a window or balcony, avoiding direct sunlight. Keep the area ventilated for at least two days. Using a fan to increase airflow can help speed this up.

During the first few days of use, avoid storing the chair in a closed or damp space. Keeping the area dry and well ventilated will help the odor fade more quickly. If you have any concerns, feel free to contact us.

This is usually caused by a loose or unstable USB connection under the seat.

Check the USB-C Connection 
Look under the seat cushion to find the USB-C cable. It may have come loose or disconnected due to the chair's movement. Unplug the USB-C cable and then plug it back in firmly—ensure it is pushed all the way into the port. Once reconnected, test the buttons again to see if the functions have restored.

Further Assistance 
If the functions still don't respond after reinserting the cable, there may be an issue with the port or internal wiring. Please record a short video showing the USB-C cable being plugged in, the status of the port, and you pressing the buttons. Send this to our support team so our technicians can troubleshoot the issue for you.
