They are very comfortable specially for my back, they are stirring after I place a little felt pad under one of the legs before it was a tiny bit shorter , ( you can see it on the photo it did not sit right that’s why I gave it 4 stars.   I did not feel  strong enough to send it back just for that.  When the check them they should make sure they are all the same. I would buy more if I had room for another, but maybe I will later the Christmas are over.
