I am using the guest bed, it wasn't comfortable enough so I added this. I thought there would be 2 inches of foam, then the eggcrate but it was 1/2 inch foam then the eggcrate. Didn't make a difference at all. I bought my daughters 4" memory foam, WOW, those are great. If it was 2 solid inches it would be good enough for a guest bed. I was dissappointed.
