A mattress includes features that improve support and comfort. The mattress may include one or more of a head section positioned to support a user's head, a torso section coupled with the head section via a first multi-plane bond, and a foot section coupled with the torso section via a second multi-plane bond. The foot section may be retractable, and the torso section may include a cross-linked foam part and a seat ledge. The seat ledge is positioned to define a catch point for the user upon articulation of the mattress.
