a good choice
Color: Black, Size: Pack of 1, Color: Black, Size: Pack of 1
Assembled chair only to find that the lift cylinder was faulty. Would have preferred to be able to just get a replacement cylinder but calling China didn't seem like a viable option. Guessing which one & buying it online would involve paying for a good portion of what the chair cost. Customer service could only offer a replacement or refund. We're disassembling (so much fun?!) to send it back. The chair itself was very comfortable, assembled fairly easily and instructions pretty clear. Again, if we could only have asked the seller for the replacement part......**Update**...Or if the instructions that seemed so clear were clearer!, as we started to disassemble, we decided to see what would happen if the tension knob (see photo) was loosened. IT ALLOWED THE LIFT CYLINDER TO WORK. Not at all what the instructions say. At any rate, we're keeping the chair.

This chair is amazing

⭐⭐⭐⭐⭐
Absolutely love this chair! It was super easy to assemble—I had it set up in no time with clear instructions and minimal effort. The comfort level is fantastic; the seat cushion is just right and the back support makes it great for longer sitting sessions.
The color is beautiful in person—clean, modern, and adds a fresh pop to the room without being overwhelming. I also really like the smooth wheels and sturdy build; it feels stable and well-made.
Overall, this is a great combination of style, comfort, and value. Highly recommend!

Easy instructions, comfortable cushions
Color: Pink
I just put it together and I love it!!! It's so comfortable and it was easy to put together. You can rock it back and forth which helps your back. The seat is very wide and the cushion is thick. Pink is my favorite color, and this chair satisfies my pink obsession.
