I had to sleep on the mattress that came in our RV for one night. Thankfully this mattress came the next day. I love it! I think it's very comfortable. My husband likes a firm mattress and thought it would be way too soft. After the first night he agreed that it is a comfortable sleeping mattress. It is different with the shorter length. Many nights I wake up with my feet hanging off, but I guess it's the price you pay when you don't have the room for a full sized mattress. I would absolutely recommend this to anyone with an RV.
