The mattress is a great deal. It’s memory foam, so it’s on the firmer side. Your body still sinks into the bed a bit. I bought one for each of my kids and they love them. They come in a relatively small box and when you open them, they almost immediately swell to size. Great find. I would recommend. I laid on the bed just to leave an honest review. Definitely worth the money. Especially since they’re 12” thick.
