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

Highly recommended for a home office
