Had trouble putting the head rest on. Excess plastic from the mold had to be cut off and filed down. The chair is OK but not the one I was expecting. Hard to adjust the tension for the back of the chair. Hard plastic arm rests are a bit uncomfortable. The chair I thought I was ordering has padded arm rests and a better headrest - but did not come in blue - I got confused with so many similar chairs with small differences. Would return it and buy the one I want but it is no longer on sale!
Headrest does not fit properly to align the holes so that you can actually attach it. Not happy I paid for a piece I will probably have to zip tie to the chair to potential use it.
