Multilayer mattress.

The mattress system provides adjustability for individuals. A stack of individual mattress elements includes separation sheets to allow the mattress elements to flex and compress separately. In a side by side arrangement for adjusting the mattress between sides for each of two users, modulator foam panels and a movement isolation foam block can be provided to reduce disturbance between sides and to make the centerline between sides more comfortable. Between side by side mattresses or between the mattress and a surrounding foam frame, edge separation sheets allow the mattresses to move up and down without catching or wearing at the interfaces.
