Please also consider custommattressfactory.com for your replacement mattress. They can make any size you want. Other places for this kind of work are charging $800+ for a mattress for our Diamond-in-the-Rough. The one we are having made for us is only $495 from this place and its 6" think!. 3-4 week lead times with the foam industry shortage. I will post an update later with pictures and how it sleeps. We go camping mid June.
