After years of chasing various budget-friendly foam solutions in our truck shell, tent trailer, and Flippac, everything we tried, from firm to soft, left us with sore hips and shoulders. I finally bit the bullet and purchased an Exped Megamat Duo air/foam mattress, it’s really great. Inflate it less than you think and no more sore hips and shoulders. The only other solution I’d like to try is the Froli spring system + foam, but is not compatible with our Flippac.This is a great subject! What cushion, foam, or mattress should I get for the top bed? I would love to hear from our experienced audience. My top mattress needs to be about 48 to 50" x 75" (a 3/4 full, or RV mattress). I like the mattress below, but I need it cut into three pieces like the bottom picture.
