I put a zrest on top of my Helinox cot. Combo is a little heavier then your standard pad, but is more comfortable then my memory foam mattress at home. I run a quilt instead of a bag and get most of my weight savings back. The cot is one piece of kit I’d replace with another without hesitation if it comes to that.
That's a good combination. My cot is an Alps Mountaineering Ready Lite. It's slightly heavier but I pack with llamas so that's not an issue. Any cot with some insulation can turn a rock pile into a good bed.
