What was the most comfortable foam bedroll you have used and how much did it weigh?

Switched to a Z-Rest and seeing what's out there.

Thanks

Ridgerest and Z-rest are my two favourites. I found the Z-rest wears out pretty quickly compared to the Thermarest, so not as good for a longer term investment, but it does pack smaller. I also find the thermarest to be slightly warmer.
