Some of my answer would depend on the material the frame is. If wood that you
can sink screws into, or plastic or metal that screws or bolts can be put
through would secure the board, plywood. If you can secure the board around
the edge a thinner material can be used. Even one fourth would work if you
have at least one inch of material past the hole where the screws would go. If
you don't intend to fasten it down half inch will work unless someone is very
overweight.

Subject: [BlindHandyMan] outdoor love seat?
We have an outdoor love seat which is not comfortable because the
straps either stretch and move or break. they seem to be made of a
solid plastic stuff about a 32nd of an inch thick. I'm thinking of
putting a piece of plywood under the cushion. What thickness of wood
should I use?
