The air mattress we got actually according to my kids was quite comfortable. It was only $45 at Academy. Also got 2 twin air mattress for $8 each. This came in handy and worked well for our family. I can easily let out the air and get my sewing room back. All the furniture moves easily on my hardwood floors along with a set of casters on the larger cabinet. The air mattress for the bedroom is a queen and was pretty firm.
