I went on a four night trip and used this and another extremely similar (and expensive) pad from a large outdoor retailer. The first night I used the larger retailers pad and could feel he ground under me when I re-positioned throughout the night. The next night I used this pad and never felt the ground and slept wonderfully ( I am 250 pds). My 9 year old got to use the other companies pad the remainder of the trip. I was sold on this one! Get this: This one was $35 cheaper and easier to inflate than the other one. That is a deal!

I did not know until the next morning, but I was sleeping on my side all night and this pad was so comfortable that I did not notice the rock that was under my tent.

I was a little on edge buying an air mattress going to Philmont Scout Ranch, but it worked out great! Cheap and Comfortable I could sleep great after hiking 10+ miles a day, over 100 miles.
