I'd probably use a piece of plywood, about 3/8" thick.  Any thinner and it might crack.  Round the corners and edges so it doesn't rip the upholstery.

 

Or you can try...I haven't used it so I can't tell you if it works.

Usually there is already some form of spring support under the base of the couch. Sometimes just a tightly attached fabric is all that supports the cushions.

 

In your situation I would recommend using a 1/2 - 3/4 inch smooth finished plywood panel.

 

If the panel is too thin then you run the risk of sagging or warping. Using any other material will yield the same results of sagging over time.

 

Just lay the panel on top of the base support (below the cushions). You may want to add some double sided carpet tape to the bottom of the panel to prevent it from sliding out.  Also, consider the possibility of the cushions sliding over the surface of the panel. Maybe adding some rubber backed contact paper will help.
