I’m 100 sold on these beds. We renovated our new to us home and I bought 4 of these for my 4 boys. I was unsure if it was a wise decision because of the many comments about them not rising. All 4 were inflated within 24hrs, but I did let them sit untouched for a full 72. This bed is definitely worth it. It is more of a medium-firm for an adult. For my kids with less body weight, it is a firm mattress and doesn’t mold around them at all.
