      It was a bit tricky to unwrap. It was easy to position on the loft bed. Light enough for 1 person to move. Perfect for a child's bed. Not designed for adults. My granddaughter was delighted with the hot air balloon designs on the cover.

    • Lightweight but comfortable

      The mattress is really comfortable. It's lightweight but also thin, just thick enough. My kids use it as a spare mattress to have sleep overs. So we have just used it on the floor and not a bed. It does look small so I am not sure about how it fits an actual frame, maybe it's the perfect size.

    • excellent support for the price
      Verified Purchase

      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
      Verified Purchase

      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.

    • Great!
      Verified Purchase

      It came as others said...all rolled up in a box. Once you unrolled it and lay it on the floor it literally "airs out" and rises to the right dimensions. I slept on it last night and it was very comfortable for my petite frame. Excellent for the little boy for whom it was purchased. Recommend.

    • Cute mattress, son happy!!!
      Verified Purchase

      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.
