Rest Haven 2" 5-Zone Memory Foam Mattress Topper, King

The mattress topper is very soft. As you lay down onto the mattress with the topper, you feel like you sink in. It is memory foam, so as you move, it slowly rises. As you sleep the topper holds your shape. The topper is on my daughters bed, and she did say that she thinks it keeps her slightly warmer than without the topper. She feels like she sleeps better, which is great. There are crevices designed into the topper. It is 2 inches deep. The one we got fits a twin mattress. The depth of it is like having a pillow top mattress. We have deep fitted sheets, so our twin fitted sheet set still fit over the topper without any trouble. If you have sheets that are not deep, you may not be able to have them go around the corners. The topper comes packed tightly rolled in a plastic bag. It easily unrolls and expands to it's full size. I did not notice a smell or any issue with the foam. It is worth it to have this topper. It is so comfortable and even as my twin mattress ages, I will be able to get several more years out of it with this topper.
