Fit, not features, decides between the LiberNovo Maxis and LiberNovo Omni Pro. Under 178 cm and 136 kg, choose the Omni Pro (153–186 cm). Over 186 cm or 136 kg, choose the Maxis (178–200 cm, 181 kg). Between 178 and 186 cm, weight and thigh length decide: the Maxis seat is 52 cm deep, the Omni Pro's 45 or 48 cm.
- The LiberNovo Maxis is specified for users 178–200 cm tall and up to 181 kg, certified to BIFMA X5.11, the US standard for large-occupant office chairs.
- The LiberNovo Omni Pro is specified for users 153–186 cm tall and rated 136 kg under BIFMA X5.1 and 110 kg under the European EN 1335 standard.
- The Maxis armrests open from 40 to 60 cm apart, and its backrest measures about 43 cm across the shoulders and 52 cm at the waist.
- In Australia the Maxis is sold as the Maxis Manual (Graphite) and the Maxis Airflow (Graphite or Glacier); the Omni Pro comes in one configuration in Graphite or Glacier.
- Both chairs are on the floor at Aussie Chair's Sydney and Melbourne showrooms, so the 178–186 cm overlap can be settled by sitting in each.

What do the LiberNovo Maxis and Omni Pro have in common?
The LiberNovo Maxis and LiberNovo Omni Pro are built on one platform. Both use the Bionic FlexFit backrest, eight flexible panels that reshape as you move, and the Dynamic Support System, which links seat, backrest and armrests so they recline together. Both offer five recline stops: 105°, 115°, 125°, 135° and 160°. Both stand on a reinforced aluminium alloy base.
The Omni Pro and the Maxis Airflow also share motorised lumbar, OmniStretch and Active AirFlow seat ventilation, which LiberNovo describes as the same 4,000 rpm fan on a 3,000 mAh battery, and both are upholstered in Danish Gabriel Atlantic fabric. Choose the Maxis Airflow and the feature list matches the Omni Pro almost line for line, so what you are really choosing is a size and a load rating.
The Omni Pro's aluminium alloy base. Every Maxis stands on aluminium too; the Omni SE and Omni Gen use nylon.
How do the Maxis and Omni Pro differ, spec by spec?
They differ in size, load rating and configuration. Every row below is a difference; figures are LiberNovo's unless another source is named.
| Specification | LiberNovo Maxis | LiberNovo Omni Pro |
|---|---|---|
| Recommended height | 178–200 cm | 153–186 cm |
| Maximum user weight | 181 kg, BIFMA X5.11 (large-occupant) | 136 kg under BIFMA X5.1; 110 kg under EN 1335 |
| Seat depth | 52 cm, fixed | 45 cm or 48 cm, chosen at purchase |
| Seat width | About 58 cm | About 54 cm (Tom's Guide) |
| Backrest width | About 43 cm at the shoulders, 52 cm at the waist | About 34 cm at the shoulders (Tom's Hardware) |
| Armrest width range | 40–60 cm, with a width lock | 32–47 cm (PCMag, original Omni) |
| Headrest travel | 140 mm vertical, 120 mm fore and aft | 120 mm vertical, 89 mm fore and aft |
| Configurations in Australia | Maxis Manual (manual lumbar dial, no electronics) or Maxis Airflow (motorised lumbar, OmniStretch, Active AirFlow); the Maxis Electric is not sold here | One configuration: motorised lumbar, OmniStretch and Active AirFlow standard |
| Fan runtime per charge | Maxis Airflow: up to 24 h on low, 10 h on high (Maxis product page); no fan on the Manual | Up to 36 h on low, 9 h on high (Omni Pro product page) |
| Colours at Aussie Chair | Graphite, Glacier (Maxis Manual in Graphite only) | Graphite, Glacier |
The fan figures are a quirk, not a real gap: LiberNovo says both chairs use the same fan and battery, but each product page quotes its own runtime. The Maxis also gets a six-spring Controlled Recline System and a Class 4 gas lift that LiberNovo says TÜV Rheinland tested through 20,000 cycles. The full specification is in our LiberNovo Maxis big and tall guide, and how it sits is in our LiberNovo Maxis review.
LiberNovo's Maxis render: the Omni Pro's backrest idea on a broader frame and a 52 cm seat.
Why is size the whole question?
Because the two chairs overlap only between 178 and 186 cm, and inside that band the seat decides. The mistake we watch weekly in the showrooms is choosing on feature lists when the real question is whether the chair fits you. Our counter rule: under 178 cm and 136 kg the Omni Pro is your chair, and over 186 cm, or above 136 kg, the Maxis is.
Seat depth settles most of the overlap. Tom's Hardware's long-legged 180 cm tester found the Omni Pro's 48 cm seat a little short, and a 178 cm, 96 kg Omni Pro owner on Reddit felt slightly pushed forward on it. On the Maxis, a long-legged 187 cm owner measured about 52 cm of usable depth and lost the pushed-forward feeling he had on his Omni, and a 188 cm owner called it the first chair to support his full thigh length.
The Maxis can also be too much chair. Gadget Review's 188 cm, 82 kg tester called it "the better-built chair and the worse fit": he floated in the backrest and the lumbar did less. A slim 191 cm owner found the armrests set too wide. Height alone does not make you a Maxis buyer; breadth and weight count as much.
Below 178 cm, LiberNovo itself says the 52 cm Maxis seat may feel deep and suggests a footrest. That leaves shorter people above 136 kg as the one group neither chair fits cleanly, so for them a sit-test is not optional.

How much does body weight change the answer?
Often more than height does. The Omni Pro is rated 136 kg under BIFMA X5.1 and 110 kg under the European EN 1335 test. The Maxis is rated 181 kg under BIFMA X5.11, the large-occupant standard, which is built around a 181 kg (400 lb) user and requires a seat at least 55.9 cm wide; the Maxis cushion, at about 58 cm, clears it.
A common retailer rule of thumb, not a standard, is to choose a chair rated about 25% above your body weight, because dropping in, leaning and pushing off the armrests load a chair dynamically. On that rule the Omni Pro suits sitters up to about 109 kg and the Maxis up to about 145 kg. So a 180 cm buyer at 120 kg is a Maxis buyer even though the Omni Pro's height range covers them. BTOD's 178 cm, roughly 136 kg tester had no trouble with the Maxis seat height or depth.
Should you buy the Maxis, the Omni Pro or another LiberNovo?
Buy the LiberNovo Omni Pro if
- You are under 178 cm and comfortably under 136 kg, which covers most of the people we fit in our showrooms.
- You are 178–186 cm with average-length thighs, and the 48 cm seat feels long enough when you sit fully back.
- You want the full powered stack without choosing a configuration. See the LiberNovo Omni Pro.
Buy the LiberNovo Maxis if
- You are over 186 cm. Nothing in the Omni line is specified for you, and force-fitting is how tall buyers end up with a backrest at mid-shoulder and a headrest touching air.
- You are above 136 kg, or close enough that the margin bothers you.
- You are 178–186 cm with long thighs, or broad enough to want armrests that open to 60 cm. Pick the Maxis Airflow for powered lumbar and the fan, or the Maxis Manual for nothing to charge. See the LiberNovo Maxis.
Consider the Omni Gen or Omni SE if
- You fit the Omni range but do not need seat ventilation: the LiberNovo Omni Gen keeps motorised lumbar and OmniStretch on a nylon base.
- You want no electronics at all: the LiberNovo Omni SE uses a manual lumbar dial. Our LiberNovo Omni SE vs Omni Gen vs Omni Pro comparison covers all three trims.

What are the honest risks of each chair?
LiberNovo Maxis: a firm seat and armrests that can move. LiberNovo says the Maxis Airflow cushion is noticeably firmer than the Manual's. A 187 cm owner put it at 10–15% firmer than he would like, with sore thighs at the front edge after several hours. The armrests lock for width, but BTOD and Basic Tutorials both found the pads shift when you push on them, and one 188 cm owner, whose armrests slid every time he pushed back, returned his Maxis Manual citing back pain and went back to his Aeron Size C. The recline stops are limits, not locks, and Gadget Review found it heavier to move than the Omni.
LiberNovo Omni Pro: depth runs out at the top of its range. Near 186 cm or 136 kg the Omni Pro is at its limits, and long-legged sitters notice the 48 cm seat first. Its lumbar adjusts in depth only, with no height setting, and some owners on LiberNovo's own product page report armrests that pivot too easily.
Both: a young brand. Neither chair has a long ownership record. LiberNovo's Trustpilot score was 3.0 out of 5 at our last check, with complaints mostly about direct-shipping delays and returns, and some about wobbly armrests and missing parts. Buying locally removes the shipping and returns part: an Australian retailer, Australian consumer guarantees, chairs already in the country.
Should a tall buyer consider the Herman Miller Aeron Size C instead?
Consider it if you are tall but not broad. The Herman Miller Aeron Size C covers 178–200 cm, the same band as the Maxis, on a mesh seat 47 cm deep per Herman Miller's Australian specifications. Its weight rating is quoted two ways: 181 kg per Herman Miller's 2026 EMEA product sheet and 159 kg on Herman Miller's size chart and Australian retailer materials; we plan around the conservative figure. That makes the Aeron Size C the mesh option for a tall, lean frame, and the Maxis the one for a tall, heavy or broad frame. We sell the Aeron brand-new and 100% genuine; our Aeron size guide explains Sizes A, B and C.
FAQ
Is LiberNovo a good brand?
LiberNovo is a young brand whose chairs reviewers rate highly: BTOD calls the Omni top-tier for comfort, GamesRadar gave the Omni Pro 5/5 and GameRevolution gave the Maxis Airflow 10/10. Its Trustpilot score was 3.0 out of 5 at our last check, mostly over direct shipping and returns. Aussie Chair is the authorised LiberNovo retailer for Australia and New Zealand.
What is the weight limit of the LiberNovo Maxis?
The LiberNovo Maxis is rated for users up to 181 kg (399 lb) and certified to BIFMA X5.11, the US standard for large-occupant office chairs, with a Class 4 gas lift. The LiberNovo Omni Pro, by comparison, is rated 136 kg under BIFMA X5.1 and 110 kg under the European EN 1335 standard.
Which LiberNovo Maxis configuration is sold in Australia?
Aussie Chair sells two LiberNovo Maxis configurations. The Maxis Manual has a manual lumbar dial and no electronics, in Graphite. The Maxis Airflow adds motorised lumbar, OmniStretch and Active AirFlow seat ventilation, in Graphite or Glacier. Both are on the floor in Sydney and Melbourne; the Maxis Electric sold overseas is not part of the Australian range.
Is the LiberNovo Omni Pro worth it?
The LiberNovo Omni Pro is worth it if you are 153–186 cm, comfortably under its 136 kg rating, and want everything in one configuration: motorised lumbar, OmniStretch, Active AirFlow seat ventilation, Gabriel Atlantic fabric and an aluminium base. If you do not need the fan, the LiberNovo Omni Gen keeps the motorised lumbar and OmniStretch.
Can I try the LiberNovo Maxis and Omni Pro side by side?
Yes. The LiberNovo Maxis and LiberNovo Omni Pro are both on the floor at Aussie Chair's Sydney showroom in South Granville and Melbourne showroom in Nunawading, with visits by appointment. Sit in each for twenty minutes, fully back in the seat, and check where each seat ends against the back of your knee.
Sit in both before you choose
Both chairs are on the floor at our Sydney showroom (Unit 11, 46-50 Wellington Rd, South Granville NSW) and our Melbourne showroom (Shop 1a/280 Whitehorse Rd, Nunawading VIC), with visits by appointment through our showrooms page. Give each one twenty minutes. If your thighs hang past the Omni Pro's seat or its ratings read thin, the LiberNovo Maxis is your chair; if the Maxis feels like more chair than you fill, the LiberNovo Omni Pro is. We deliver across Australia and New Zealand.
