Before purchasing I was a bit skeptical of foldable mattresses and their overall support. After reading the reviews I decided to purchase a Queen Size for my Hybrid Camper Bed End. Followed the setup directions, and allowing it a few days to fully expand, we finally tested it while on our weekend camper outing. I was amazed at the overall support is gives, and very satisfied to have a great nights sleep. What also sold me on this mattress was the ability to tri-fold it. PERFECT for a Hybrid Bed end for those who know about Hybrid campers. And light weight too. We are very HAPPY CAMPERS with our new mattress.
