Basically you would create geometry in two states. One is deformed and the other is not. Once you have that, you can use a BlendShapes node to cross-fade between them. Add a little bounce using keyframes or CHOPs on the cross-fade control.
To make the deformed state, you could try the the technique in this video. (not vellum).

Here's a simple vellum setup. The cloth constraints make the mattress surface act like cloth, obvriously, the struts give it internal strength and a bit of fake pressure, so pushing down on one end will make it bulge elsewhere.
To get the memory foam effect I used ‘damping ratio’ on the bend and stretch sections of the cloth constraints. Higher numbers will make it restore to the original state even more slowly.
