  • Great to go with Bunk Beads in previous review

    Fit perfectly in the Bunk Beds previously reviewed. They are firm and comfortable. The Grandkids love them.

  • good for bunks_cover on pad tore a bit

    Working well for our bunks (that have a large number of slats rather than a solid surface). the only thing I'd say is make sure the length will work for you. it takes awhile for the pad to spread out after coming in the box. the cover on the mattress/the seam isn't way will it last years (it tore as my kids jumped on it uncovered) but it will stay in a zippered mattress cover that I bought separately so not a big deal.

  • Bunk Beds

    Bed is wonderful, delivered when stated. Their where no instructions, but retrieved them on line. One problem is the slats provided for the lower bunk are not sufficient to keep the bodies from falling through. I was required to buy thin box springs to alleviate the problem.

  • excellent support for the price

    I purchased this for on top of my son's box springs as they were still in good condition. It fit perfectly & provided fresh comfort for my son. The sheets fit over the 2 mattresses together as if made for them. I would surely buy this product again. It is a great help that the mattress is hypoallergenic & will not shred like other foam products.

  • 5-inch Twin Size Foam Mattress

    The mattress arrived in a small box, which I carefully opened, as it was going to pop to size once released. Placed it on the twin mattress frame and it looked too short, but in 48-hrs it sized to exactly the size of the bed frame. It is extremely comfortable. The quality of the stitching is excellent, as is the cover of the mattress. The odor disappeared in about 3-days, but until then, I found it quite stinky! I would recommend to anyone who needs a twin mattress that does not go on top of a box spring. You can use it with either slats or a metal frame. I think everyone who is the right size to fit on a twin bed will be most comfortable and have a good nights sleep.

  • Cute mattress, son happy!!!

    I got this product about 2 months ago.Just like most of the other reviews, I did smell the chemical smell when first un-packaging the mattress. I let it air out in a spare bedroom for 2 day before using it for my son's new bed. A couple of days later, I asked my 6 year old if he smelled anything funny about his bed and he said "No". I asked him if he felt comfortable in his bed and he said "Yes". I recently laid on his bed and it felt firm to my taste but my little one has not complained about his bed.

  • Foam mattress

    I purchased the foam mattresses because we could not get an ordinary mattress through the hatch on the boat. When they arrived we could not believe there were TWO mattresses in that tiny box until we opened it. All the air had been pressed out of them and they were rolled into a tight cylinder. It actually made them very easy to handle and move around. Once they were in place I cut off the shrink-wrap and watched them grow, and grow, and GROW, like some b-grade Sci-fi movie. If you have kids, let them watch, they'll get a charge out of it! Once they finished growing, I tried one out. It was very comfortable even though it was on a plywood bunk with no springs. I'm quite happy with them.
