KingCamp Self Inflating Sleeping Pad, R 7.9 Air & Foam Sleeping Pad for Camping, 3" Thick Single Camping Mattress with 3D Sidewalls & Wave Surface Cut for Outdoor Tent Cot Car, PVC Free (Black)

This mattress was too large for my purpose.... sleeping in my SUV when camping. There was no explanation regarding how to fill it. I struggled to get air in it and even used a pump... but nothing seemed to work. I finally found a video that showed a valve in the opening that swings around. In one direction the air will flow in.... push it with your finger and flip it around and then the air will flow out. Just a simple instruction sheet would have saved me a lot of frustration. It seemed sturdy and comfortable enough. The biggest reason I didn't want this camp pad may sound silly... but it was important to me... I wanted a black pad which it stated that it was. When I received it, it turned out to be brown, which I didn't want.

I took it out of the package for the first time today to use it camping and it wouldn't inflate so it’s basically worthless. (I should have tried it when i got it but it was new so i didn't think it was necessary). Now i am out the money and not going to sleep well.
