Really like the chair the instructions were very clear and all the hardware was separated and labelled. Chair not as cushy as a leather one but I like the breathable mesh and is easily adjustable. Good lumbar support also adjustable.
The head rest is way too low to be of any use or function the arm rests and back of the chair come lose even after making sure they were tight the mesh is starting to become lose a couple weeks later and to top it off the reason I got this chair was for my lower back problems and it doesn't help at all. The price was the main appeal.
I replaced a much more expensive chair that had reached "end of life". The Hykenchair is as comfortable and seems to give me the same back support as the old chair for about half the price. A good product that does the job.
