I can't say enough good things about both the product and my interactions with the company. I checked the seat out on line a few times before ordering. All of my queries were answered immediately. We had a discussion on chat abut the hight of my desk, how much time I spend sitting, compared to standing at the desk, and I scrambled around with a tape measure during the chat. As a result, I now have the perfect seat for my desk. I couldn't wait for it to arrive, and I couldn't be happier with the end product. My sitting bones are delighted. Thanks Salli.
