Young bucks who can sleep on granite and wake up feeling sporty.............. GFY!
At 50+ years old my trusty 80's thermarest just isn't getting it done. I get a poor night's sleep due to hip and shoulder pressure points. Digging depressions for them helps but isn't always practical.
Cost no object and it doesn't need to be the lightest- if it really works.
Wife has a NeoAir and it might work... seems awefully fragile though.
