I tried the velcro with no such luck..... the velcro won't stick to the back of the cushions very well.
I like Ladywendolyn's idea of snaps. There's always duct tape.
As for the fridge, ours kept freezing my beer.... now I don't mind very cold beverages but frozen beersicles was getting to be a bit much. Anyhow found out from Jayco there is a knob in the back of the fridge ( as mentioned from Samque ) top right hand side that you can adjust... there is an actual cutout in the wood panel to get your hand in there to adjust it.
