Abstract
A mattress converts from a crib mattress with side walls and end walls surrounding an infant sleeping surface on a central mattress section therebetween to a twin mattress with a substantially planar sleeping surface to support a reclining child or adult. The end walls and side walls are tethered or hingedly connected to the central mattress section and are moveable from an upright position (crib mattress) to an open position (twin mattress). Sidewall extensions are hingedly connected to the side walls and are pivotably moveable from a first position above the side walls to a second position axially aligned with the side walls when the side walls are in the open position.
