I originally had the cheapest chair on the market and this chair was difficult to get used to. Trust me when I say this I thought I wasted my money and I was disappointed for a few days. After a week I am very comfortable with this chair and I am getting more accustomed to it. The back rest can be adjusted along with a multitude of other things my overall posture is a lot better and this chair is breaking my bad habits. After you get acclimated with the small back rest and the head rest you'll learn to love this chair. I give it 5 stars it was a solid addition to my work space.
i am 5'7" tall. I never had backpain. after using this chair for couple of days I started having backpain and headache. the lumber support is pinching all the time. There is no way to remove lumber support plastic thingi.
bought this chair as recommended by a colleague and found it very sturdy and comfortable. Its heavy stuff which need to assembly with other person. Can’t do alone as its heavy chair but good quality one. very recommended to buy.
