We purchased these twin mattresses for our 3 and 5 year old grandsons. We also have a queen size in our camper and 2 in our family summer cottage, anyone who sleeps on them gets a really good night sleep. We change them out every 5 years (probably) could go longer, but that's our choice.

Great mattress

I was a little skeptical at first when we took it out of the box. It took a few hours to fully form and seemed like it would be too short to fit in a bunkbed by several inches, but it eventually fit perfectly. Our toddler really likes it and it's a great product. Would recommend this mattress 10/10.

Comfortable to Make You Want to Sleep In

I purchased these for the grandkids ages 4 and 5. They slept so well on these beds. It was finally nice for the to sleep in on the weekend until 7/8am, instead of getting up at 5am. LOL! They totally enjoyed their sleep. As an adult laying on the matress, I felt that it was comfortable and contours; with my weight (168), however, I'm thinking the matress would last about 2 years before I would need to buy a new one. For the kids, though, it will last much longer. For the price and comfort, It's great!
