That's why I said "relative comfort".

I'm 5'11", 160. I can't stretch out, but at least it'll be more comfortable than if I DIDN'T have the pad!

I also have a king-size Tempurpedic bed at home. I'm spoiled now. Best bed I've ever slept in!

(Well...except maybe for that feather bed in Germany, but the two German college girls had more to do with those memories, I think...)
