We have two of them. Over 20 days at a stretch USER! Almost as cozy as an original bed. Improper transport, I had a small hole in the side. It was found in 10 minutes and very easily repaired within 3 minutes with the included patches. If after 100% tightly held. The fleece on top is very pleasant.
Even better: If two people I recommend two mats of this size because it then it does not sway and can be a normal bed sheet over this evert. The measurements are adhered to.
