So I read most of the reviews about uneven legs on this chair. This is a DIY project, so level of install differs for each person. The issue with uneven legs is with the installer and uneven flooring in our homes. On average each chair took me 30 mins, only because I am a perfectionist and would not settle for an unbalanced chair and had plenty of times on my hands  So I screwed and unscrewed the legs until it was just right. The last chair took me over a day to install  It just won't balance right.

In summary this is a fun DIY, not one to rush. I am sure a paid professional would complete a chair in 10mins. So for all you DIY that have uneven chairs right now, take it apart and start all over ..lol
