    • very comfortable

      We spent 2 weeks sleeping on this mattress in our camper. No backaches or soreness, so it was a good buy.

    • Good night's rest!

      This thing fits in the back of the truck and it rocks. Never slept so well. Prefer it to my dreaded pillow top indoors! Works great for big guys too because it doesn't squish!

    • Excellent mattress for boat

      I bought this mattress to replace the worn-out foam in the aft berth of my 27' Hunter sailboat. The mattress is incredibly comfortable even compared to my mattress on my bed at home. Makes for a wonderful sleeping experience on the boat at anchor. So far it has handle the humid environment just fine. Also, haven't had any problems in regards to smell.

    • Good Value

      I bought this mattress for a three-quarter size bed that I use in my study for guests and TV viewing. I had been planning to spend about $600 to get a custom-made mattress, saw this on Overstock and decided to take a chance. It arrived very promptly and was easy to unpack. The mattress has already reached its full size and appears to be a very good value for the price ($*** including shipping). Thanks, Overstock!

    • Just what I was looking for!

      Was looking for a mattress to fit a 1974 pop-up camper. Was worried that this might be a bit too long at 75", but took the gamble, hoping I could squeeze it into the 72" bunk frame or have it altered. When I first unrolled it, it was a few inches short of the 72" frame. After a couple days, it expanded to 'almost' fill the frame. If you need a 75" mattress, this may be a bit short, but was perfect for what we needed. And much more comfortable than the 3" thick 37-yr-old foam mattress that came with the camper!

    • Best mattress for the money that we could find

      We have a camper that needed a new mattress and looked extensively for a replacement. The camping stores mattress STARTED at about $400 and other places on the internet were not much better. I was a little concerned that since this mattress came rolled up in a box that we may not like it. Even as we opened the box, the concern was still there. After rolling it out on the bed in the camper and a couple of days passes, we realized that it was as described by Overstock. I will however put a matress pad on it for a little more softness (but then I have them on all my beds) and look forwards to getting lots of use from it. I highly recommend it!

    • I am looking for a replacement mattress for our Sleeper Sofa in our camper. Do these mattresses fold up as a sofa bed mattres would?

      • Hello shereedavid, foam mattresses need to expand and remain

      • Hello shereedavid, Yes, this mattress can fold up into a sleeper sofa. However, InnerSpace does have mattresses specifically designed for sleeper sofas. I would recommend using one of those because they feature the most commonly used dimensions for sleeper sofas and this is what they were designed for. We have included the link for InnerSpace mattress. Thank you for checking with us.,/brand,/2019/subcat.html?sort=top+sellers&TID=PRODPG:BRAND:TX:COLLECTIONS

    • Your ad say not for home or mobile home use. That seems very odd.

      • Thank you for your inquiry for the InnerSpace 6-inch 3/4-size RV Foam Mattress. This item is made for a RV because there is less space but you can use it in a camper trailer or a mobile home.

    • how are these shipped? i will be ordering 2 for my pop-up camper

      • They came rolled up in a box. After you take it out and remove the plastic it flattens out. It came quickly. I put it in another room overnight because I didn't like the fumes. Smells fine now, though.

      • Mine came rolled up in a long box, wrapped tightly in plastic. No smell for me when I left it to expand.

    • Looking for mattress 47 by 73 Will this work?

      • This mattress is 48 inches wide by 75 inches long, making it one inch longer in each dimension than you specified.

      • The size of the bed I would like to buy is 45 x 72, but I am thinking 47 x 73 may be workable.

      • This is 48 x75 so you would have to squash it a bit. but it should work because it is foam
