Abstract: The bed includes a support structure and an actuatable mattress support platform, which actuatable mattress support platform has a reclinable back section and an actuatable leg section. The actuatable leg section includes a reclinable thigh section and a reclinable lower-leg section that are adapted to move in conjunction with one another. The reclinable back section and actuatable leg section are actuatable to adjust a configuration of the actuatable mattress support platform and change the configuration of the actuatable mattress support platform from a substantially flat configuration to a sitting configuration, or vice versa. During a first actuation phase, exclusively the actuatable leg section is actuated to raise the actuatable leg section with respect to the support structure, thereby bringing the actuatable leg section to a first intermediate position with respect to the support structure.
