The LiberNovo Maxis is LiberNovo's big-and-tall ergonomic chair: sized for 178–200 cm, rated to 181 kg, with a fixed 52 cm seat and a wider Bionic FlexFit backrest. It suits sitters who are tall and broad. Australia gets two configurations, the Maxis Manual and the Maxis Airflow, both in stock and on our Sydney and Melbourne showroom floors.
- LiberNovo recommends the Maxis for people 178–200 cm tall and up to 181 kg (399 lb), and certifies it to BIFMA X5.11, the US standard for large-occupant office chairs.
- The seat is fixed at 52 cm deep, with a cushion about 58 cm wide and 7 cm thick per LiberNovo's FAQ; the deepest Omni seat is 48 cm.
- The backrest spans about 43 cm at the shoulders and 52 cm at the waist, and the headrest travels about 140 mm vertically.
- The Maxis Manual sets lumbar support with a hand-turned dial and has no battery; the Maxis Airflow adds motorised lumbar, OmniStretch and a fan-ventilated seat on a 3,000 mAh battery.
- LiberNovo's own pages quote the Airflow fan at anywhere from 24 to 36 hours per charge on low and 9 to 10 hours on high, depending on which product page you read.
- Every Maxis has five recline positions from 105° to 160°, a reinforced aluminium base and a Class 4 gas lift tested to 20,000 cycles.
- Aussie Chair is the authorised LiberNovo retailer for Australia and New Zealand; the Maxis Electric sold overseas is not part of the Australian range.

What is the LiberNovo Maxis?
The LiberNovo Maxis is LiberNovo's big-and-tall chair: the Omni's Bionic FlexFit backrest and linked recline, rebuilt around a wider, deeper seat. LiberNovo's FAQ says it is not the Omni scaled up; the seat, backrest, armrests, neck support and recline were all redesigned for larger bodies.
Its weight rating comes from BIFMA X5.11, the large-occupant standard whose test basis is a 181 kg (400 lb) sitter. That standard also requires a seat at least 55.9 cm (22 in) wide, which the Maxis cushion clears at about 58 cm. LiberNovo rates the chair to 181 kg; one launch report printed 188 kg, but every LiberNovo page says 181 kg.

Who does the LiberNovo Maxis fit?
The LiberNovo Maxis fits people 178–200 cm tall who are also broad or heavy. LiberNovo's FAQ says sitters under 178 cm may find the 52 cm seat deep and should add a footrest, and that above 200 cm it cannot guarantee a fit.
Testers bear this out. BTOD's tester at about 178 cm and 136 kg had no problem with seat height or depth, and Geeky Gadgets' 196 cm reviewer found the headrest reached his neck rather than his upper shoulders.
The mismatch is the tall, slim sitter. Gadget Review's 188 cm, 82 kg tester called the Maxis Airflow "the better-built chair and the worse fit" for him: his back never filled the backrest, so the lumbar did less.
For weight, a common retailer rule of thumb is a rating at least 25% above body weight, which puts the Maxis at sitters up to about 145 kg. Australian heavy-duty chairs are often rated under AFRDI 142, whose classes are 135, 160 and 185 kg; the Maxis's BIFMA rating sits between the top two, though the standards differ.

Maxis Manual or Maxis Airflow: which should you choose?
Choose the LiberNovo Maxis Airflow if you run hot or want powered lumbar adjustment; choose the Maxis Manual if you want nothing to charge and a softer seat. Both share the frame, seat, backrest, recline, aluminium base and 181 kg rating, so the fit is identical.
| Configuration | Lumbar | Extras | Battery | Upholstery | Colours |
|---|---|---|---|---|---|
| LiberNovo Maxis Manual | Manual dial | None | None | Micro-elastic fabric, over 60,000 rubs | Graphite |
| LiberNovo Maxis Airflow | Motorised | OmniStretch; Active AirFlow ventilated seat, two speeds | 3,000 mAh, removable, USB-C | Gabriel Atlantic, over 100,000 rubs | Graphite, Glacier |
The Airflow's centrifugal fan sits beneath a layered cushion and moves air through the seat at about 40–41 dB on low, per LiberNovo. LiberNovo's Maxis page quotes up to 24 hours per charge on low and 10 hours on high, its Omni Pro page 36 and 9 hours for what it says is the same fan and battery, and a seat sensor pauses the fan when you stand. Basic Tutorials and GameRevolution, using the fan regularly, charged about weekly.
The Manual's case is simplicity and cushion feel: LiberNovo describes its seat as softer, and the Airflow's as firmer because of the structure around the air channels. Sleek Setups' reviewer preferred the Manual's dial lumbar; BTOD recommends the Airflow for most buyers.

How is the LiberNovo Maxis related to the Omni?
The LiberNovo Maxis is the Omni platform on a bigger chassis. It shares the Bionic FlexFit backrest of eight flexible panels, the Dynamic Support System that links seat, backrest and armrests, and the five recline positions with the Omni SE, Omni Gen and Omni Pro. What changes is size and load.
The Omni line fits 153–186 cm and is rated to 136 kg under BIFMA testing and 110 kg under EN 1335, with a 45 or 48 cm seat chosen at purchase. The Maxis moves to 178–200 cm, 181 kg and a fixed 52 cm seat, with about 20 mm more vertical headrest travel than the Omni Pro and an armrest width lock the Omni lacks.
The Maxis Manual mirrors the Omni SE's dial lumbar; the Maxis Airflow mirrors the Omni Pro's fan system, 3,000 mAh capacity, Gabriel Atlantic fabric and aluminium base, though one buyer was told by LiberNovo that the Omni Pro spare battery does not fit the Maxis.
The ranges overlap from 178 to 186 cm, where build decides: BTOD does not recommend the Omni above about 188 cm, while slim sitters may float in the Maxis. Our LiberNovo Maxis vs Omni Pro guide works through that band, and LiberNovo Omni SE vs Omni Gen vs Omni Pro covers the smaller chairs.

LiberNovo Maxis vs Herman Miller Aeron Size C: which suits big and tall?
Both chairs are sized for 178–200 cm, so the difference is load and seat. Herman Miller's 2026 EMEA product sheet rates the Aeron Size C to 181 kg, while Herman Miller's size chart and Australian retailer materials give 159 kg; we plan around the conservative figure. On the 25% rule of thumb, 159 kg suits sitters up to about 127 kg, against about 145 kg for the LiberNovo Maxis.
| Chair | Recommended height | Maximum user weight | Seat depth | Seat height |
|---|---|---|---|---|
| LiberNovo Maxis | 178–200 cm | 181 kg (BIFMA X5.11) | 52 cm, fixed | Not published by LiberNovo |
| LiberNovo Omni Pro | 153–186 cm | 136 kg (BIFMA), 110 kg (EN 1335) | 45 or 48 cm, chosen at purchase | About 48.5–59.5 cm (Tom's Hardware) |
| Herman Miller Aeron Size C | 178–200 cm | 159 kg (Herman Miller size chart, Australian retailer materials); 181 kg (Herman Miller 2026 EMEA sheet) | 47 cm | 40.1–57.9 cm |
The seat is 47 cm deep on the Size C and 52 cm on the Maxis. Sleek Setups describes the Aeron's three sizes as one design scaled, whereas LiberNovo redesigned the Maxis around its larger seat. One owner notes that both use recline limits rather than a lock.
The Aeron's advantage is its long service record, and fit stays personal: one Reddit owner at 188 cm and 95 kg returned his Maxis Manual for his Aeron Size C, citing sliding armrests and back pain. We stock brand-new, 100% genuine Aerons alongside the Maxis. Our Herman Miller Aeron size guide covers Sizes A, B and C, and best big and tall office chairs in Australia widens the field.
What are the downsides of the LiberNovo Maxis?
Reviewers and owners keep raising five LiberNovo Maxis drawbacks, each worth checking in person.
- Firm seat on the Airflow. LiberNovo itself describes the Airflow cushion as noticeably firmer than the Manual's, BTOD found the Maxis firmer than the Omni, and a 187 cm Reddit tester rated an Airflow 10–15% firmer than he wanted, with sore thighs at the front edge after several hours. Manual owners describe the cushion as plush.
- Armrest drift. The armrests lock for width, but BTOD, Basic Tutorials and several owners report the pads sliding as you shift or push off them.
- Lumbar strike point. Sleek Setups found the motorised lumbar rises at an angle as it extends and can press into the mid-back.
- Battery on the Airflow. The fan, lumbar motor and OmniStretch share one battery, Basic Tutorials found no battery-level indicator, and LiberNovo's FAQ notes heavier sitters draw more from the motor.
- A young brand. The Maxis is LiberNovo's newest chair and has no long-term track record, and BTOD reported slower LiberNovo customer service as demand grew.
Also: the recline positions are limits, not locks, and Gadget Review found the Maxis heavier to move than an Omni.
FAQ
Is the LiberNovo Maxis available in Australia?
Yes. The LiberNovo Maxis is in stock in Australia in two configurations: the Maxis Manual in Graphite and the Maxis Airflow in Graphite or Glacier. It is on the floor at our Sydney and Melbourne showrooms, with delivery across Australia and New Zealand. The overseas Maxis Electric is not sold here.
What is the weight limit of the LiberNovo Maxis?
The LiberNovo Maxis is rated to 181 kg (399 lb) and certified to BIFMA X5.11, the US standard for large-occupant office chairs, whose minimum seat width its 58 cm cushion clears. On a common rule of thumb of choosing a rating 25% above body weight, it suits sitters up to about 145 kg.
How tall do you need to be for the LiberNovo Maxis?
The LiberNovo Maxis is sized for people 178–200 cm tall. Below 178 cm the fixed 52 cm seat can feel deep, and LiberNovo suggests adding a footrest. Above 200 cm LiberNovo does not guarantee a fit and recommends checking seated shoulder height, leg length and headrest reach in person before buying.
Should I buy the LiberNovo Maxis Manual or the Maxis Airflow?
Buy the LiberNovo Maxis Airflow if you run hot or want motorised lumbar and OmniStretch; LiberNovo's pages quote 24 to 36 hours of fan use per charge on low. Buy the Maxis Manual if you want no battery, fewer parts and, by LiberNovo's description, a softer cushion. Fit, frame and the 181 kg rating are identical.
Is the LiberNovo Maxis better than the Herman Miller Aeron Size C for big and tall?
For heavier, broader sitters the LiberNovo Maxis gives more margin against the figure we plan around: it is rated 181 kg with a 52 cm seat, while Herman Miller rates the Aeron Size C at 159 kg on its size chart and Australian retailer materials (181 kg on its 2026 EMEA sheet). The Aeron has the longer track record.
What is the difference between the LiberNovo Maxis and the LiberNovo Omni?
The LiberNovo Maxis is the big-and-tall version of the Omni platform. Both use the Bionic FlexFit backrest and five recline positions, but the Maxis fits 178–200 cm and 181 kg with a fixed 52 cm seat, while the Omni SE, Gen and Pro fit 153–186 cm and 136 kg under BIFMA (110 kg under EN 1335) with a 45 or 48 cm seat.
Can you adjust the seat depth on the LiberNovo Maxis?
No. The LiberNovo Maxis seat is fixed at 52 cm deep with no slider; LiberNovo says sliding would shift its three foam-density zones out of position under the thighs. Long-legged sitters get full thigh support, while people under 178 cm may find it deep, and LiberNovo suggests pairing the chair with a footrest.
Where can you sit-test the LiberNovo Maxis in Australia?
You can sit in the LiberNovo Maxis at our Sydney showroom (Unit 11, 46-50 Wellington Rd, South Granville NSW) and our Melbourne showroom (Shop 1a/280 Whitehorse Rd, Nunawading VIC), alongside the Omni range and the Herman Miller Aeron.
