The fact that you can get a really comfortable mattress shipped to your house with a great price is so cool! I read a lot of mattress reviews, this one was the best reviews. Got it home, super heavy of course. Open with plenty of space for it to fold open, it‘s kind of bent like a taco lol When you open it, it springs open it like a angry butterfly ?? almost got me in the face lol my fault of course! Glad we didn't do a how to video! We let it rest for 24 hours so it can breathe and the foam can expand, seemed like it was done by mid day but we let it sit the full 24 hours. First night of sleep without my husbands shoulder hurting, he's a side sleeper, I'm also a side sleeper so my lower back is always hurting. Woke up with no hip or lower back pain! It's very comfortable, not too hard, not too soft. No smell to it. The grand kids jumped on it to test out the springs, it held up just fine lol I like that I don't need a box spring for it and it's high enough without being too skinny of a mattress.
