This is a simple one. For many people, sleeping in a hammock is more comfortable -- MUCH more comfortable -- than sleeping on the ground. An Amazonas Traveller hammock is cheap -- less than $20. Grab one and set it up in the back yard or at a park, take a nap. If you are one of those "many people" above, then buy a camping hammock suitable to the use to which you'll put it. Don't forget a good tarp. There's enough info on the pros and cons of the various manufacturers in threads on this site for you to make an informed decision once you take that nap -- and sell yourself (or not).
