Opened it up and the mattress immediately started to expand. 3 hours later we were sleeping on it. It was perfect, very comfortable, both soft and firm. The foam mattress we purchased 3 years ago would make it a bit of a struggle when I needed to turn over. The new mattress doesn't have that problem. In fact, a new queen size bed with a bed frame is less than $400! Now I'm going to buy the same set of furniture for my mom's house, she has a guest room for us to use and needs a king size bed. Highly recommended!
