We purchased these mattresses for our kids bunk beds several years ago in Twin size and were very pleased. Foam expanded as it should and very comfortable. Purchased this mattress in Twin XL size, and two weeks later both ends are still hard and compact where the foam has not fully expanded. This makes it uncomfortable to sleep when the top of bed is angled down.
