Product details
The LiberNovo Omni is the model in the range that gives you the motorised backrest. A 50 mm powered actuator drives the lumbar support in and out under a button on the armrest, so you change how firmly the chair holds your lower back without standing up or reaching behind you. The same motor runs OmniStretch, a five-minute cycle that walks the lumbar slowly through its full travel to move your lower back while you stay seated. That motor is the single thing that separates the Omni from the Omni SE, which does the same job with a manual screw dial and has no motor at all.
It is also the most flexible model to specify. Four colours — Starship Grey, Midnight Black, Space Grey and Moss Green — against the SE's one, and, on most colours, a choice of chair-only or chair plus the independent two-stage StepSync footrest. If you want the powered lumbar and the stretch cycle but do not need the Pro's ventilated seat or Danish Gabriel upholstery, the standard Omni is the one to buy.
- Motorised All-In-Fit lumbar — 50 mm of powered travel, driven from the armrest control
- OmniStretch — a five-minute powered cycle through the full lumbar range
- Bionic FlexFit backrest — eight linked flexible panels that articulate as you shift, rather than one rigid shell
- Four locking recline positions, 105° to 160° — Deep Focus (105°), Solo-Work (120°), Soft Recline (135°), Spine Flow (160°)
- 2,200 mAh 12 V battery, USB-C, about 3 hours 40 minutes to charge; one stretch cycle a day runs roughly 30 days between charges
- 4D armrests (height, depth, angle, width) and a height- and depth-adjustable headrest in hydrophilic memory foam
- 48 cm extended seat — 3 cm deeper than LiberNovo's 45 cm standard seat, and supplied with the full-size neck support. LiberNovo rates the chair to 136 kg (BIFMA; 110 kg under EN 1335)
- Chair weight about 21.8 kg; seat height roughly 44–55 cm; zoned multi-density foam seat
Aussie Chair is an official authorised LiberNovo dealer for Australia and New Zealand, so every Omni carries LiberNovo's manufacturer warranty — six years on the frame, two years on the motor and electronics — and every claim is handled by Aussie Chair locally, with parts held in Australia. Try it at our Sydney (South Granville) or Melbourne (Nunawading) showroom.
Omni vs Omni SE vs Omni Pro
All three share the same frame, Bionic FlexFit backrest, 4D arms and recline positions. The differences are in the lumbar drive and the seat:
| Model | Lumbar | Seat | Colours | Best for |
|---|---|---|---|---|
| Omni SE | Manual dial, no motor | Zoned foam, 48 cm | Obsidian only | The simplest way into the LiberNovo backrest |
| Omni (this chair) | Motorised, 50 mm travel, OmniStretch cycle | Zoned foam, 45 or 48 cm | Four | Most buyers — powered lumbar at the mid price |
| Omni Pro | Motorised, as Omni | Ventilated seat, Danish Gabriel fabric | Three | Hot rooms, long sessions, premium finish |
If you are torn between the three, our Omni vs SE vs Pro comparison walks through the differences and who each one suits. For a longer hands-on account of the standard Omni, read the Omni review, and to see how it stacks up against Sihoo's dynamic chairs, see Omni vs DORO S300 vs C300 Pro V2.
Seat depth: 45 cm or 48 cm?
Most colours ship with the 48 cm extended seat and the full-size neck support; Space Grey is also offered with the 45 cm standard seat. The rule of thumb: measure from the back of your knee to the back of your buttocks while seated and subtract about 5 cm. Under roughly 48 cm, take the 45 cm seat; over it, the 48 cm. If you are around 170 cm or shorter, the 45 cm seat usually fits better; taller users almost always prefer the 48 cm. Both depths are on the floor in Sydney and Melbourne, so sit in both if you are close to the line.
Bundles and accessories
- Basic Bundle — the chair with headrest, armrests and battery; no footrest.
- Standard Bundle — adds the independent two-stage StepSync footrest, which slides under the desk when you are not using it. It is the configuration most people pick for the 135° and 160° recline positions.
- StepSync Mat — protects timber floors under the footrest and stops it creeping.
- Spare battery pack — swap rather than wait if you run the stretch cycle several times a day.
- CloudSoft cover set and CoolTouch seat pad — made for the Omni and Maxis frames, for a colour change or a cooler seat in summer.
Two things worth knowing before you commit
The armrests move easily — helpful when you are setting them, mildly irritating when you knock them out of position and have to reset them. And the backrest spine projects roughly 20 cm behind the chair, so check your clearance if it backs onto a wall or a walkway. Assembly takes longer than an ordinary office chair: allow around 30–40 minutes, or ask for assembly when you pick up from a showroom.
Stock and delivery
Current pricing for the Basic Bundle and the Standard Bundle with the footrest is shown above on this page. Stock is held in Australia and ships Australia-wide and to New Zealand; same-day pickup is available from both showrooms.
FAQ
What is the difference between the LiberNovo Omni and the Omni SE?
The motor. The Omni has a powered lumbar with 50 mm of travel and the OmniStretch cycle, controlled from the armrest; the SE uses a manual dial and has no motor or battery. The frame, backrest, arms and recline positions are the same.
How long does the Omni battery last?
About 30 days between charges if you run one five-minute stretch cycle a day. It charges over USB-C in roughly 3 hours 40 minutes, and the lumbar position holds without power.
Should I choose the 45 cm or 48 cm seat?
Most people over about 170 cm are better in the 48 cm seat; shorter users usually prefer 45 cm so the front edge does not press behind the knee. Both are on the showroom floor to compare.
What warranty does the Omni have?
Five years on the frame and two years on the motor and electronics, as set by LiberNovo. Aussie Chair is an authorised LiberNovo dealer, and every claim is handled by us in Australia with parts held locally.
Does the Omni come assembled?
It ships partly assembled. Allow 30–40 minutes with the included tools, or ask us to assemble it when you collect from a showroom.
Can I try the Omni before buying?
Yes. All four colours and both seat depths are on the floor at our Sydney and Melbourne showrooms, with the SE and Pro alongside for comparison.
Love the chair. Has back support all in the right places and the footstool is a dream. Awesome for those long days at the desk.
I’m extremely happy with both the product and the service. The guys here are incredibly friendly, helpful, Overall, a very smooth experience from start to finish. I would definitely recommend this store if you’re looking for a good ergonomic chair in Australia.
good chair
Amazing chair, fast delivery and great service.
Fantastic value and comfort. The chair cushioning and lumber support is incredible. The electric adjustment works very well. Some of the toggles and adjustment points are on the lighter side material wise. But the bones of the chair are really solid. Would also recommend the foot stool if you have the space, it is great for mixing up your seating position during the day.
