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!

Great chair, only one issue.

Number of Items: 1

As someone who is exactly 6ft tall, this chair is just about perfect for my height and body type. High quality materials, adjustable lumbar support, very ergonomic. Visually, it works well with my desk setup. It has already helped me improve my posture ten-fold. My only complaint might be that the tension on the recline joint is too much. Twisting it to the loosest setting doesn’t feel loose enough, you’ll need to put your feet up on something to recline comfortably and stay in that position. Other than that, great chair. I don’t see myself returning this one.
