+1 on the Thermarest. It seems to be filled with lots of walnut-sized chunks of foam. You roll it up to compress it into a significantly smaller bundle but then it snaps back into shape once you open it back up. The fabric cover tends to cling to the hammock fabric pretty well so it stays put once you're laying on it.
I've had mine for years and it just goes through the washer every few trips. Maybe make your own as already mentioned. Chop one of those fancy foam pillows in half and make a cotton or fleece cover.
