This is very comfortable on my child's bed. It has been in constant use for 2 years now and is holding up perfectly. Great product!

  • Great memory foam.
Style: 3 Inch Color: Blue Size: Full
I bought this because it was less expensive than dog bed inserts. We've had a brand name dog bed for about five years and the foam inserts were toast, so I purchased this to cut up and replace the inserts. I'll tell you what, our dog sleeps in now and I really think she likes it a lot. I laid down on it while it was on the ground, and while I sunk to the floor, I was pretty comfortable. If you want a nice thick topper, that you can sink into and have it form to your body, I think this will do a nice job. It had very little smell to it, which is my alarm bells for plastic product, and the three inch thickness seemed just about right if I were using this for my bed. Enough to sink into but not too much to make sheets not fit. If you want to cut this foam up into dog beds, this one is perfect. The size is about an inch shy of stated dimension. ... show more

  • Very Comfortable
Quite good, it does cool and very comfortable. When you open it you have to let it sit out for some time to basically inflate.
