excellent product probably for seasoned campers/hikers but for occasional campers staying in a cabin with no mattresses this didn't work for me. I weigh 180 and this item didn't give me much comfort..but if your a seasoned hiker/camper it may be perfect for you..very light to carry, easy to inflate and deflate..
