Nice Chair
I’ve never seen a chair this good-looking. It’s not just stylish — it actually looks even better in person. The moment I saw it, I knew I had to get it. Now that it’s in my room, it steals the spotlight from everything else — even the stuff in my display case.

Black Panther Vibes with a Personal Back Massager
I’m obsessed! I bought this executive chair purely for the looks—that S-shape aluminum spine and polished back is just stunning. But the comfort is the real shocker. The adaptive lumbar system is genius; it adjusts to my back as I shift, so I get support whether I'm sitting straight or fully reclined. Plus, the 4D adjustable armrests are perfect for my work/gaming setup. It’s an investment, but my spine is sending me thank-you notes.

Finally, an executive chair that looks like a sculpture but supports you like a personal physical therapist—the adaptive lumbar is pure luxury.

It's truly worth the purchase.
I almost passed on this because I expected genuine leather at this price, but the breathable material is a real bargain for long workdays. The polished back and S-shaped spine are so beautiful that I finally decided on it, but upon receiving it, the adaptive lumbar support and adjustable headrest are the real highlights—it feels like it's custom-made for my upper body.

Pictures Don't Do It Justice
It looks ten times better in person. That S-curve aluminum spine on the back catches the light in a way the camera just can't capture—it's incredibly sharp and high-end.
Beyond the aesthetics, the support is just unbelievable. Just sit, and the chair adapts to you, keeping your back perfectly cradled even when you tilt back. It’s an investment, but this is the kind of support and style you keep for years.
The Difference Is in the Details
Multifunctional headrest
The hidden headrest has a lifting function and can adapt to the angle as your neck moves.
Tracking lumbar support
The lumbar support automatically adjusts its angle as you lean back.
Soft PU adjustable armrests
The armrests can be raised and lowered, angle adjustment, and rotated 360° around the central axis.
Dimension
It's digging into my back right now. I don't know how to adjust it back.
Everything else about the chair is great, but this one setting is ruining the chair for me right now.
Hi brandon,
Thank you for reaching out, and we’re very sorry for the discomfort you’re experiencing.
To clarify, the lumbar support on this chair does not adjust forward or backward. It is a self-adaptive lumbar support, designed to slightly change its angle when you lean back, helping maintain contact and prevent your lower back from losing support — but it does not retract away from the body.
If the lumbar feels too far forward or too firm for your body type, we understand how that can affect comfort, and we sincerely apologize that this is impacting your experience. Please contact us so we can better understand your situation and discuss possible solutions.
Please feel free to contact us at 1-844-416-2060 or customerservice@eurekaergonomic.com
if you need any further assistance.
Best regards,
Eureka Ergonomic
I used to get back pain after sitting for long periods, but this chair has completely changed that. The support is fantastic!
My old chair scratched my floor constantly. This one rolls quietly and smoothly—big upgrade.
The pictures don't do justice to the sheer awesomeness of this chair. The all-aluminum alloy frame and the metallic feel of the back panel are just so cool. I initially considered buying a gaming chair to match my gaming desk, but thankfully I didn't. This chair is a hundred times cooler than a gaming chair, and it's just as comfortable as an ergonomic chair. The designer is absolutely brilliant!
I use it for both work and gaming, and it handles both perfectly. The adjustable angles let me switch positions easily.
