I've had the deep sleep solo mattress for a bit over a year and used it on multiple camping trips. It's incredibly comfortable and fits the Jeep perfectly. It self inflates so that's a huge plus. I got this product because my other air mattress was simply too big for the back of the Jeep.
But you do have to use the pump to deflate as it's to difficult to try to roll up and get all the air without the pump. That's really not a big deal as the pump gets out almost all the air and the last bit can be rolled out easily.
There is a second valve which supposedly can be used to adjust the firmness during use. I've not used.
I'd heartily recommend this product to any other Jeep owners.
