This is a very serious mattress! It was easy to remove it from its packing and it puffed up quickly and easily, I let it sit for a couple of days before attempting to put the cover on it. The cover that it came with would have been good as it was quite substantial. It definitely took two of us to find the hinge and get it to bend into the upright position but once we got it there all was well! The reason I took off one star was because it is VERY firm and I can tell right now I'll have to get a topper for it to make it sleep-able. I'm sure it'll relax some with use but this is our bonus room which only gets occasional use. Nonetheless, we are very pleased!
