Ive had this air mattress over 2 years now and have used it a lot.  For the money I don't think there is a better one for camping.  There is no insulation like many camping pads have but as far as comfort and durability,  you cant spend $10 on a better investment.  Its not heavy,  its plenty big enough for one person and doesnt take up too much room in a tent.  Blowing it up manually takes a little time and patience,  its basically a thick pool float but a little bigger than the standard size pool float.
