Review on Experience Ultimate Comfort On The Go With QDH SUV Air Mattress - Portable Car Bed For Travel & Camping In Blue And Black by Jesse Wells

I purchased for a mini road trip. I have slept in my car before (a RAV4) and wanted to be able to create a similar ability in my more efficient Prius. This mattress fit perfectly in the space and was surprisingly comfortable. Unlike an air mattress in a room where you can roll off, the mattress is nestled in the car. The entire back area is filled with air mattress. No weak areas to sink off into. That is great support.Some suggestions: Like all air mattresses, it will lose air over time. Be ready to 'top it off' just before bed. If possible, inflate it mostly, but not fully before you arrive at your intended place to sleep. That means less to do when you are tired and just want to rest. Don't fill it fully because heat from sitting in sun in the back of the car may expand the air too much causing some air loss, then cool air at night will make the mattress feel too soft.For reference I am 6'3 230lbs. I did not have to share the space with anyone. My only issue was the mattress gives some additional height to the back so I had to watch my knees on the ceiling of the car. That was something I was not accustomed to in my RAV4 but just had to be adjusted for in the Prius.
