So is this" pillow' supportive? My wife got an inflatable matrice for a familly / car camping trip we took with the little kids a while back and the sag and sqishey softness of it all almost killed me.   I'm (almost) "funni'n now, ... but I still can't stand up straight.   For most of my life I've used either a folded up wool blanket or a 3 quarter length ,1(?) inch thermo rest self inflating pad I got in the early eighties. I'm always going to wake up "stiff" now but I think I should be able to not be freezing and crippled by dawn   Would the ThermoRest product (I don't know which one would be best) give me some needed "support"that the "comfy" pillow from Agnes would not?. I'd really appreciate some experienced comment on this. 100 to 150 $ plus shipping is saddly", huge!'  right now. If I have to, I'll stick withthe folded up wool blanket...   ...I'll just briing alot more 'rumatiz' meds. (12yr kentucky sippin' types_) :dankk2
