I'm 5'3" so I have a difficult finding a chair that's comfortable with head/back support that won't make my legs go numb after a while since my feet hang and don't touch the floor. This chair fits me. I also like the under seat lock that locks the tilt function. I can see how a taller or heavier person would not like this chair but for those of us under 5'6" it works great.
I will say I have been very pleased with this chair so far. From how comfortable it is to the ease of assembly. Instructions were fairly easy to follow and the only time I need a second pair of hands was when attaching the head rest. The positioning is pretty easy to get right to meet my sitting needs. I would recommend this chair to anyone. Very Pleased!
