while big and wide seat is nice this chair has just seemed off since i got it, it seems like it only reclines part way and it feels like it is leaning forward in normal sitting position and one of the wheels fell off the mini ball bearings fell out of the swivel part of the wheel and left the wheel unstable only to fall off. while the actual seat of this chair is big and wide (not so comfy) the mount seems off and cant recline all the way back like in old chairs, the wheel thing suck but i can replace a wheel could have been much higher quality for what i paid for the chair. UPDATE: over the past few weeks customer service reached out to me about the chair and fully addressed all of my concerns, to my surprise they offered to replace the chair at no cost to me. The new chair is much better than the old one everything seems good to go and i got upgraded wheels that dont have that same type of ball bearing, so i dont think these wheels will be an issue. Thanks to the customer support member Luka that reached out to me and made everything correct.

Nice Chair but it does not work for long.

Color: Black

This is a very good chair when you buy it. Comfortable and fits bigger people well. The issue is that you only get to enjoy it for one year. After one year of very light use the main seat piston that adjusts high has already failed leaving my chair stuck at the lowest height. I could not imagine how fast it would have failed if I used it a lot. I did not even sit in this chair more than 3 days a week for 2 hrs. I am nowhere near the weight limit for the chair. It just does not last.

Ergonomic Office Chair

Color: Nori Black (Pu Leather Seat), Color: Nori Black (Pu Leather Seat)

I’ve been using this ergonomic office chair for about a week now and honestly it’s one of the best upgrades I’ve made to my workspace. The chair was easy to assemble, feels very sturdy, and the mesh back keeps it breathable during long work sessions. The lumbar support is surprisingly comfortable and actually helps with posture, especially if you sit at a desk for hours every day. The seat cushion has the right balance of firmness and comfort, and I like that the armrests and height are adjustable to fit different setups. The wheels roll smoothly and the chair feels stable even when leaning back. Pros: ✔️ Comfortable for long hours ✔️ Great lumbar support ✔️ Breathable mesh back ✔️ Smooth rolling wheels ✔️ Modern clean look
