Don't buy this! I followed instructions, let it expand for a full week. It never did look anything like the pictures, appears about 3/4 full. Because of this there is a lot of excess cover that is just a wrinkled mess. Comfortable when you sit down but since it is not full you sink into a hole. It is just a disappointment. It's huge and heavy. I roll it around everyday some but I am one person so I can't push it around long. They want $55.00 shipping to return it. However it comes with the foam compacted in a box. It is no longer compacted so the thing is huge( not going back in the box for sure) so impossible to ship. How could you pack this huge heavy thing and couldn't carry it anyway. So I'm stuck with it. It was my 1st and last purchase from Wayfair. It looks nothing like the picture. I don't mind the shape being different but it's just an ugly wrinkled mess and I'm out $230.00.
