Since it is often desirable for greater padding under the hips and shoulders I have tried gluing layers of closed cell foam pad together. I found that this can be accomplished with contact cement purchased at the hardware store. It makes a very strong bond and you only need a few dots of it to hold things together. By overlapping pieces, I can now make myself a custom pad to my height and width with padding at just the spots I need. This way I eliminate a ground sheet, and have a warm full length pad with a surface that doesn't promote condensation. As weather turns colder, you can add additional layers of foam. One of my customers uses grommets and toggles in his hammock to keep the pad in place. Foam pads for sale.
