We have just now had the opportunity to try our DeepSleep mattresses in the Subaru Impreza. We were hesitant the first night to comment but the second night of our camping expedition .Oh here we go . .Reason first night to adjust air pressure. The second night we slept superbly well .Slept in even till 8:45 am , witch never happens. We appreciate the quality and versatility of your mattresses. Thank you.
