Excellent Office Chair
Color: Black+white, Size: Pack of 1
I just received my TRALT Office Chair. First of all, I was impressed with the packaging of this item. When I opened the box each piece of the chair was wrapped in plastic or bubble wrap. Everything in the box arrived safely and without damage. Secondly, the instructions to assemble the chair were very each to follow. I was impressed with the Allen wrench which had a handle attached to it. This made screwing in the screws very easy. I was able to assemble the chair without any difficulty. Lastly, the look of the chair and the comfort is exceptional. I ordered the black/white chair which looks amazing. The comfort of the chair is really excellent. My back is supported by the lumbar seat and having the armrests being able to go up when not needed is wonderful. The quality of the chair is definitely worth the price.

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.

⭐⭐⭐⭐⭐
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!
