Sleeping on dinette, cushions slipping

Rubbery rug underlay

Some of mine have Velcro under them, but assuming the table top is part of the platform it may depend on your layout if that would work.

Carpet underlay works well. I used the 1/2" foam type once for dinette seating and no more slipping. IIRC, foam underlay is somewhat slippy on one side and I seem to remember using spray contact cement to glue it down to the plywood. Would have to store a piece for when the table is used for sleeping on and would be bulky.

A yoga mat might work even better, only about 1/4" thick too. Just used some in our under-bed storage and am surprised how well it works at stopping things from moving around. Rolls up into a fairly tight bundle. Can be found cheap on CL.

Great suggestions! I was also thinking of a memory foam mattress cover.

After folding the dinette down my cushions are such a tight fit they can not move around. Are you sure you are putting them down the right way ?

Maybe other campers are different from mine.

I have this same issue, and fixed it just this past weekend. It seems that I have a couple of inches of play in the cushions when laid down in bed mode, causing whomever is sleeping there to slip down a bit.

I take the armrest cushions from the sofa (really anything will work) and jam them into the crack at the head, causing the cushions to have no play, and not slip. Problem solved.

Caveman - They are all going in the correct way; they fit snugly but separate when slept upon.

Wishbone - I don't have any other cushions to use, perhaps I'll try a pillow.

We stapled some antislip shelving material on top of the seat boxes and that worked for us. Sounds like you need a filler block, how about a pool noodle?

A pool noodle would be perfect... I think I'll try that next time.

Fitted sheet? It is what we use.
