I’m shocked and appalled by the design of this chair, it’s impossible to sit in. I put the base on as shown in the picture, sat in it and the base of the chair touches the floor, I was tipped back in shock, which then gave me severe pain in my stomach as I had a hernia through the unexpected shock... I was in agony and could not get out of the chair ... it’s a shocking design flaw... my 9 year old child sits in it and it’s around 2 inches off the floor at the back..and she is very slim. I’m absolutely devastated and have not sat in it since and I’m too scared too and I never want that pain again!!! I DO NOT RECOMMEND THIS CHAIR.
