Definitely happy with this purchase!
Color: Nori Black (Pu Leather Seat), Color: Nori Black (Pu Leather Seat)
I’m really impressed with the MUXX.STIL Office Chair. I wanted something comfortable for long work days but also stylish enough to fit nicely into my space, and this chair ended up being exactly what I was looking for.
The PU leather looks sleek and elegant, and the chair feels much more premium than I expected. It’s comfortable even after sitting for hours, with great back support and a soft cushion that doesn’t flatten out quickly. I also love how smoothly it rolls and adjusts.
As someone who spends a lot of time working, editing content, and answering messages at my desk, having a comfortable chair truly makes a difference — and this one does. It made my workspace feel more put together and cozy at the same time. Definitely happy with this purchase!

Nice-ish chair but not what I expected.
Color: Grey
Nice chair basically, good looking, and assembly went well, the wheels roll very nicely, lumbar support is good too, with comfy seat back. However, the "seat cushion" design itself is very odd, because the seat cushion is much thicker at the rear than it is at the front, thus you're constantly slipping off forward, always needing repeatedly to lift up and get back on the seat up further where you belong; while the seat tilt adjustments are of no help with this problem, no matter what setting you will be slipping off forward. The lever for adjusting reclining ability is very cumbersome and awkward to use. The arm rests are ok, comfy, but lack the ability to raise or lower, all you can do if flip it up totally out of your way. I wish I could return and exchange this chair for something better but there is no way this could easily be disassembled and returned in the box that is long since gone. This came in a box really super efficiently and very tightly packed, give them credit and kudos for the great packing design. Maybe, hopefully, the manufacturer has some suggestions for replacement when they see this review.

Surprisingly Comfortable for Long Hours
I was honestly expecting one of those oversized chairs that look comfortable in pictures but feel cheap in person. This one actually feels solid. The seat is wide without feeling awkward, and the cushion is thick enough that I don’t feel the frame underneath after sitting for a while.
The armrests being adjustable was a bigger deal than I thought, especially for working at a desk for hours. It also rolls much smoother and quieter than my old office chair.
Assembly took some time, but nothing complicated. Once put together, it feels sturdy and doesn’t wobble. The reclining function is nice too when taking breaks or watching videos.
Overall it feels more “heavy duty” than most chairs in this price range.

Big Guy Approved – No More Chair Drama
Finally found a big and tall office chair that doesn’t quit on me. The 600lbs support feels rock solid, and that wide spring cushion? Like sitting on a couch at my desk. I use it for work, gaming, even late-night scrolling—still comfy. Smooth wheels, adjustable arms, ergonomic back… it just works. If you’re tired of chairs tapping out early, this one’s built different.

Worth every penny.
This chair is exactly what I need for working from home. Its spacious seat and high weight capacity make it incredibly comfortable and reliable. The ergonomic design provides excellent back support, preventing fatigue even after long periods of sitting. The adjustable armrests are convenient and add extra comfort. The PU leather material gives it a premium feel while maintaining practicality for everyday use. I am very satisfied with this purchase and will definitely buy from them again.
