  • Not really thick enough to be comfortable

    Size is good but not really thick enough to be comfortable. I could feel the wood beneath it. But, kids would probably not notice. Ended up purchasing a regular memory foam mattress and cutting it to fit.

    • Hello William Brady, unfortunately this item is out of stock. We currently do not have inventory to check, and cannot guarantee the item will be restocked. Thank you for shopping with us.

  • My trailer bed accommodates a king size mattress. What does the term "3/4 bed size" mean? Queen? King?

  • I have a 1946 Tear drop with a "well" for the mattress that is only 47"x73". If I put it in before it has expanded do you think it will just expand as far as it can and work to fit the space?

  • 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.
