memory foam mattress pad behind screen

[richdmb]

i got a memory foam mattress pad to put behind the screen, but am having trouble with it staying up. i tried to screw it into the wall, but it falls down after a week or so. any ideas on how to secure the memory foam to the wall? thanks!

I put a baton on the wall.
put mattress into a duvet cover
attach duvet cover to baton.
i put eyelets into duvet cover at top to connect to baton.
