The chair was easy to assemble with the instructions provided. I needed one extra tool a clamping pliers as the back tension knob was to hard to turn by hand. However the tension knob works fine. The chair is very comfortable. I hope the the chair material holds up under wear.
This is the best chair I’ve ever owned for work. It supports your back and most importantly your butt while I am doing support. I recommend this chair without any hesitation.
I ordered this because my chair at work was killing my back due to no lumbar support. Now having used it just sitting in it I instantly noticed a difference! If you like me need good lumbar support this chair is for you! Order it & you will not be disappointed!
