Kara 5 Bought this instead of a futon mattress. So glad that I did, because it’s so much more comfortable than the 2 futons that I was stacking on top of each other that my 2 year old and I sleep on daily. I lay it right on the floor like a futon. It’s right against my real bed so I can roll up and down to my daughter as she needs me in the middle of the night.No smell. Inflates to it’s fullest capacity within 2 days. It’s also very affordable!!
