An In-Depth Look at the LiberNovo Omni SE

Two months, one chair, and a cushion that had to be replaced – twice. This isn’t a review in the strict sense. The only other chair I’ve used long-term is an IKEA Nominell, so I can’t offer broad comparisons. What I can offer is an honest account of living with the Omni SE – plus a few observations most reviews skip.

Where I’m coming from

My background shapes what I look for in a chair, so it’s worth stating up front.

I never had back problems with my old IKEA chair, but I credit that to regular exercise rather than to the chair. In my experience, exercise is by far the most effective way to prevent back pain – closely followed by changing posture throughout the day: standing up now and then and putting your leg muscles to work.

The upshot: for me, the specific chair matters less than people assume. What I value instead are quality-of-life features – freedom to move and the ability to recline deeply for a quick moment of relaxation. That’s the lens I judged the Omni SE through.

The Omni chairs hardly need an introduction; they’re among the most aggressively marketed chairs on social media. So rather than rehash the spec sheet (Dan Ahn’s YouTube channel covers that well), I’ll stick to my own experience.

Ordering

I paid the 10€ deposit, ordered on 16 June for 589€, and received the chair on 23 June – so about two months of use at the time of writing.

The 10€ “deposit” turned out to be a one-year warranty extension rather than a deposit. Fine by me.

The seat cushion problem

The downside of ordering early and cheap: at least the first batch shipped with foam that was too soft in the seat cushion.

The Omni cushion combines three foam densities, with the firmest section only near the backrest. Even that section wasn’t firm enough – once the foam warmed up, you’d sink through to the plastic pan. Steve, the Anthros CEO, summarises the issue neatly – keep in mind though, that this is coming from a rival.

If you’re reading this in a seemingly fine Omni and wonder what this feels like, sit on the front edge for a few minutes: the softer foam lets you bottom out. Sit with your lumbar against the backrest and you’re on the firm section, where it should feel comfortable.

Customer support assured me that batches produced after early May went through improved firmness testing – which means my chair was made before that. At the time of writing, it’s still unclear whether all new deliveries ship with the updated cushion. So if you’d rather not go through the hassle of getting a replacement, wait until that’s confirmed.

How support handled it

Sitting with my lumbar against the backrest was exactly where the problem showed up for me, so after a few uncomfortable weeks I contacted support via email. They replied within 24 hours, and their first suggestion was that I should sit closer to the backrest. Once I confirmed I already was, they promised a revised cushion – and noted that my return window would restart on the day the replacement arrived.

A week later a new cushion arrived – the Pro version, sent by mistake. Since the correct replacement was another month out, I used the Pro cushion in the meantime; its firmer foam didn’t bottom out. I also received a small compensation package for the inconvenience, including the StepSync Mat, which turned out to be surprisingly handy – more on that below.

The correct SE cushion arrived at the end of August, so at the time of writing I’ve used the Pro cushion for about a month and the revised SE cushion for three days.

On the two replacement cushions

The revised SE cushion is noticeably stiffer than the one my chair originally shipped with, across all three foam zones.

The Pro uses Gabriel Atlantic fabric, which the active ventilation requires because it allows more airflow. It’s also more durable. The trade-off is the coarser weave: less soft and slightly scratchy compared to the standard fabric.

In terms of firmness, the two replacement cushions feel about the same to me – the fabric is the main difference. Upgrading to the Pro just for the fabric isn’t worth it in my view.

Backrest and recline

The backrest is what LiberNovo builds its marketing around, and deservedly so. Sitting down for the first time, it was the most noticeable difference to my IKEA chair: it hugs you around the lumbar region and you immediately feel supported, without limiting your range of motion.

The second standout is the recline. If you’ve ever wanted to lie back for a moment of relaxation and quick back relief, that’s what the 160° position gives you. Even at maximum recline the chair feels stable – but to be genuinely comfortable, you’ll want to raise your legs. Whether that calls for the official footrest is up to you; I put the StepSync Mat on the subwoofer under my desk and called it a day.

Day to day, though, I keep the chair locked at 135° with the tension tightened up – that lets me move freely back and forth while still getting the back support.

Armrests

These get called out as a weak point, so I’ll say plainly that I like them. Yes, they slide forward and backward very easily – but for me that’s an advantage: I can pull up to the desk and the armrests simply move out of the way. If you prefer them to stay put, I can see it being annoying.

The one real drawback: at the two narrowest width settings they collide with the backrest unless fully extended forward.

Material-wise, the firmness and smooth surface are pleasant. Keep in mind, though, that my old chair had no armrests at all.

The standout: parts availability

The cushion swap points to what I consider LiberNovo’s real strength – not the chair itself, but what you can do with it after you buy it.

Competing brands may advertise a 12-year warranty instead of six, but their spare-parts selection is very limited. With LiberNovo you can order every individual component – and, unusually, at fair prices: building an Omni SE from parts comes to €681, against €679 for the finished chair (current price). Most brands price their spares steeply enough to make that comparison absurd.

What that enables is customization: want a headrest in a different colour? Order that spare part. Worried about the motorized lumbar? Swap in the manual one from the SE.

Verdict

After two months, I’m happy with the upgrade. The Omni SE is far more comfortable than my IKEA chair, and I use the recline often – reading a book, or just taking the load off my back.

The biggest drawback is probably the fixed seat depth. You can change it later by buying the 45 cm / 48 cm cushion replacement, but that still doesn’t let different people share the same chair.

LiberNovo recently extended the warranty to six years for everyone, which makes seven with my deposit. Since the SE has no electronic components, that covers the whole chair in my case.

My cushion wasn’t right out of the box, and it still took two months and two shipments to sort out. But the parts availability and the support response mean you’re not stuck with a problem you can’t fix – and that, more than any spec, is what won me over.

I’ll update this post if anything changes.
