Subsequently, question is, can a sofa bed be comfortable? In general, a wall bed is more comfortable than a sleeper sofa, and it all comes down to the mattress.

How do I keep my couch cushions from sinking?

Cut square sections of foam to fit inside the cushions. Unzip the cushions and add the foam sections to fatten up the cushions and reduce sinking. Use a 1/2-inch foam; you can add a second layer if one layer is not enough. Rezip the cushions and place them on the sofa.
