Expansion was immediate. No waiting at all. If you want extra firm this is it folks. That's what I wanted. The only thing I would change is the covering. Even waterproof does not protect. But I found fabulous waterpad on Amazon to solve that problem. I do not want any expensive spring loaded mattress ever again.

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!
