    • InnerSpace 5.5-inch Full-size RV Foam Mattress

      If you are stuck like I was- needing an RV mattress for a full size space, this is a low profile mattress that works. After sleeping on it I believe it is as firm as you can get without sleeping on the floor. You'll wake up stiff but no kinks. As for 5.5"- they must be counting the bead that sticks up around the edge where the top is attached to the sides. The cover is very bold and I recommend dark sheets to cover it as it will show through any of the medium to light sheets. I had read the previous reviews and was excited about this since the air mattress was not working. I am not sure if there is a quality control issue here as the mattress cover is described as a nice damask in one of the reviews and that is what sold me on it. Not so. All in all it still beats that air mattress so I would buy it again- or maybe something like it a little plusher.

    • Great mattress for a porch bed

      We selected this mattress to go on an iron bed on our screened porch - we wanted something that would work in a humid environment and would drain if it got wet (the jury is still out on that part, but I plan to buy a waterproof cover for it). Because we did not want to put a box spring on the porch, we paired it with a slatted bed foundation from IKEA (Sultan Luroy - the slats are close together and arched to help absorb the weight of the user). I don't know if it's the foam or the slats, or the combination of both, but it's very comfortable so far. Another reason I selected this mattress is that I HATE exposing my family to flame retardants (which I personally think are more dangerous on a day-to-day basis than the low probability of being in a fire). When I was looking at mattresses for bunkbeds vs. RV's, from the same manufacturer, the RV mattresses clearly said they were not allowed for use in a home. My theory is that they aren't sprayed with a bunch of unnecessary chemicals. I don't know if I am correct, but this was the reason I selected this mattress over the same style/material in a bunkbed mattress. When we unpacked it, it did not smell at all. I think this mattress is probably a little thinner than advertised (closer to 4-5"). It is very lightweight. It was a good buy, and I'm glad I didn't pay $100 more for the 8" version.

    • Excellent value

      Item purchased for full/twin toddler trundle. We also purchased gel topper and has transformed a reasonably priced mattress into a cloud. Our daughter is so comfortable and loves her new bed!

    • Fair price for a decent product.

      Arrived on time. Mattress is good quality, but not 6 inches thick. Would consider ordering a thicker pad, if ordering again.

    • looks good

      The price seems fair and the shipping went well. I received it two days ago. The product looks good, but I have not yet slept on it, since the instructions say it will expand to it's full size in 24 to 48 hours, and so far it is just shy of 5" thick. ( it is advertised to be 6".) Also it has an odor, so I have it out in the sun hoping that the smell will dissipate.

    • made for the travel trailer

      We bought the used trailer less a matress and were using an air matress. The platform lifts for storage so we needed something that would lift for access. This was ideal weight and yet gave this 250 lb. body a good night sleep I could not attain with the air matress.

    • memory foam mattress

      I love this mattress! It was everything as described and more. It is really firm but having had a memory foam mattress for 15 years, they do soften up some with use. It's an incredible value for the money. I bought this for a vintage trailer I am restoring. I can't wait to sleep on it!!!

    • Is this a memory foam mattress, described as soy-based, high density foam mattress...does not say memory foam?

      • No, it is not a memory-foam mattress. It is a soy-based mattress designed for use in an RV.

    • I'm replacing a folding mattress in a travel trailer. Someone suggested a twin or full futon mattress, but the dimensions are not right. I'm interested in your 3/4 full mattress as it's the closest size size to fit into the 50" x 73" space. Can it be folded and be used as a ( futon) sofa?
