Now, from what other people said, I was expecting a solid bed! This mattress has exceded my expectations by far! It is super comfortable, trust me. I put it on top of an idea bed frame with slats under it. It feels great. I was so surprised to see how the mattress was packed though. It comes in a very small box for the size of your item, get ready to be surprised. Overall, a great buy, get this and you won't be sorry.
