I have AS so getting and staying comfortable is very tough for me.  I use Wayfair... a lot..... and read all the reviews on everything. I make my decision based on weighing and balancing those reviews.  That being said, PLEASE trust me when I say, get this chair. You won't regret it! I have a very glam apartment and it fits in well. Beautiful, comfortable and glides like no other! Its a must have.  This is the ONLY chair that I can get comfortable in and am pain-free. I now understand why I had to wait months after I purchased it just to receive the chair but I am so glad I did.  I'm SO in love and am trying to find space for a second one!!!!
