Chair was very easy to assemble. It is a lightweight chair but not cheap. I find it comfortable and the controls work well. Extra bolts are provided which is a great feature. I find the adjustable back support excellent, the head rest moves a little to easily, but it is easy to adjust while sitting.

Overall good chair for a good price

Number of Items: 1

Comfortable chair, but there's a very slight lean. I haven't yet managed to track down what's causing it, but as I slowly spin around, I find myself tilting slightly forward, then left, then back, then right... I've removed the casters and then removed/reinstalled the "ring" of legs, so the next place to check is the connection between the post and seat.

The best office chair!!!

Number of Items: 1

The chair is great quality, sturdy, and was easy to put together. Looks just like the photos and video. It is SUPER comfortable - the most comfortable chair ever! If you’re looking to purchase an office chair/ desk chair - this is the one! The price was reasonable and I would 100% recommend!
