Hi trixieb239,
The Dreamfoam 12 in 1 customizable mattress is a new mattress so there isn’t a lot of feedback on the forum about it yet but you can see some comments about it in this thread and in this thread.
It uses higher quality and more durable foam than the Crazy Quilt (which uses 1.5 lb polyfoam while the 12 in 1 uses 2 lb polyfoam) and has more options to customize the mattress both before and after a purchase.
