I too decided to go the route of the cot. I just didn't want to be "that Guy" who's air mattress went flat in the middle of the night and left me on the ground. I still use my Big Agnes Insulated air mattress on top of the cot, have a Thermarest pillow and use a Cabela's Alaskan Guide Series Down Bag. It's a great setup and IF my mattress goes flat, I'm at least on the cot. It is a great and very comfortable setup which I highly recommend. One thing to consider is that a small tent with the door on the end is easy to slip the cot into after it's setup. My tent with the door on the side does not allow the Cot to fit in after it's setup. I did try (as others mentioned) putting it under the tent floor and it works great that way. It also won't ruin the floor of the tent. Two thumbs up on the cot!
