I've reviewed a number of products from Eureka Ergonomic - office chairs, standing desks - and each one always has a certain style to them that goes beyond the usual office furniture designs. So, when I had the chance to review the Nox genuine leather office chair, I had to check it out.

It doesn't fit the mold of most of the best office chairs I've reviewed, and maybe that's just what makes it a space in the market. This chair has a distinct vibe that will be an absolute dream - if you don't mind the executive price-tag.

The Eureka Serene Nox is an upgrade to the Standard Serene chair that I have reviewed in the past. The Nox is made of genuine leather and, like the Model T Ford, is offered in only one color: black.

It's currently available direct from Eureka Ergonomic's website, retailing for $750 - although at the time of review, it's down to $600.

Eureka Ergonomic Nox: Unboxing and First Impressions

The Eureka Nox came in quality packaging, nice protective material and a quality box. The setup was quick and painless, only taking about 20 minutes by myself to build. While most chairs have a handful of colorway options, by very nature of the name itself, the Nox comes in black, and only black.

This, paired with the sleek metal frame makes this chair look stunning. The lumbar has a slight pattern to it which is super interesting to look at, and other than that, the angular armrests are artistic over functionality, though they are fine most of the time.

This chair doesn't scream but confidently whispers high-end, professional office chair. Whether that is a top-tier executive or Bondian super-villain, I cannot tell yet. It's a bold design, all about strong lines gently tapering at the lumbar support, sweeping padded armrests that glide around the chair to the seat base. It's striking in all the right ways.

The chair has simple, yet capable controls, offering tilt and lock options, height adjustments, and tension control. The lumbar section of the chair provides a good amount of support, but doesn't affect that silhouette, remaining cool, calm, unobtrusive. One part that I noticed even more than the lumbar is the waterfall-style seat, caressing the sides of my legs and alleviating pressure at the same time.

All around, this chair is supportive, firm, yet comfortable, and minimal, all while looking beautiful. It’s perfect for a professional office, an executive suite, the Batcave.

Eureka Ergonomic Nox: In use

I’ve had this chair in my rotation for my team for 100 days. Member of my team and I have spent entire days in this chair, all without any discomfort or need to switch to another chair. The lumbar support is not the most aggressive, but that’s okay, not every chair needs to have intense lumbar protrusions.

Even after a full work day, we have not had any complaints of back pain, so I’d be willing to say that lumbar support is a strong suit of this chair. Another interesting note is that even though these armrests are not adjustable, I have yet to have a team member complain. Perhaps that is because when you sit in this chair you don’t expect it to be something that it’s not, you sit in this chair and you feel like an executive.

You could be sitting in this chair in your office with literally nothing to do, no power, on your first day and you’ll feel like you are starting with a leg up due to this chair. That’s just how this chair makes you feel when you sit in it.

There are some scenarios where these armrests may not be ideal, but for most, they’ll be fine, or worth the lack of adjustment if you like the style and overall aesthetic and feel of this chair.

Some chairs you give up look and design for overall comfort and features. The Nox is the exact opposite, you give up highly adjustable armrests and lumbar for the overall aesthetic.

That’s another element of this chair that you should probably know. You’re not going to want to use this chair with a cheap folding desk, nor at the kitchen table, where your temporary workspace is, you won’t even want to use this chair in a bullpen, you want to use this chair in offices, in executive corner suites, you want this chair at the reception desk of a high end corporation so that it can look the part and still provide comfort.

Eureka Ergonomic Nox: Final verdict

The Eureka Serene sits in a very specific niche. It’s for professionals, it’s for executives, its for those who want something that looks the part, looks professional, looks high end, and looks luxury. This chair isn’t the kind you’d see at a budget operation, but one that you would see at a highly successful firm.

And, as a result, this kind of chair makes anywhere that it is feel a bit elevated. If you are looking for a quality chair that fits an aesthetic first and foremost, then you should absolutely consider the Eureka Ergonomic Nox. But if you’re on a budget, or want something that is more lumbar supportive, than this may not be the best chair for you, maybe send the link to your boss.
