Thermarest luxury map if you’re not on too much of a budget- you can get it for a hundred. They’ve got a big budget sleep system to go with it, which will cost you a fortune, too.
else the Alpkit Dozer linked above, but that looks out of stock.
I’ve got an aerobed with rechargeable pump which is super comfortable. On the downside, there’s a lot of air in it and it can feel a bit cold on chillier nights. A nice thick sleeping bag should resolve that though!
