I had problems with the foam wedge since I often end up sleeping on my stomach. I purchased a tapered topper from Pennys (I believe this is the same one available at Walmart
). I built my own mattress from a folding gym mat, the tapered version & a standard 2" topper and used it for 2 years. The 2" topper started getting a bit soft, so this year I put two tapered toppers together; lighter, more comfortable, and provides plenty of slope. I purchased the full size version & used an electric carving knife to trim it to fit the Escape 17 bed.
