I got the foam for my WilderNest mattress from a place up in Boulder called The Foam Source. Had all kinds of foam, any size, thickness and could sew new covers if you need it. They do plenty of RV and boat stuff, so they weren't phased by what I was asking for.alia176 said:I was curious as to the best place for acquiring memory foam or high quality foam pad for sleeping. This could be for a roof top tent or a trailer based camper where 3" to 5" of foam would fit. Would these be in the usual Michael's or similar craft store type of place?
