Oh, my aching back! I sat on new cushion, instead of sportaseat and slept on too soft cushions and wow what a lower back ache I've had this week!
Quarterberth cushion did have a thermarest pad on top; no real help there.
I have a plan to fix quarterberths cushions by cutting out the top 4' and replacing with higher density foam. I figure my head shoulders and butt are what need the help.
If that works, I won't have spent too much money for a solution.
Oh, and make sure the sportaseat is handy next time too!
I know the feeling...love my Sportaseat.
