At first I was concerned because I had to put the passenger seat quite a bit up in order for the mattress to lay flat. But it turned out to be ok, and the mattress is comfortable. The valve was difficult to release but I finally got it. Obviously not made for elder hands.
I like absolutely everything about this product. It's amazing.
Love all the products. Do need instructions on how to use the vacuum to deflate the mat back to its original size
I sleep on mine 3 days a week while out climbing. Super comfy and tough. I just leave it set up and pack around it.
