Revising review after Customer Service Help
NRG® Rolling Stool with Removable Backrest - Massage Rolling Stool
I bought this same chair a couple of years ago and loved it so much, and used it so much that it needed replacing. This one arrived, and while the seat part isn't quite as soft and comfy it will definitely be a good chair. And I'm so glad that your customer service was able to help me, as my chair seemed to endure a really rough ride in shipping, so she offered a partial credit.
