A patient support is provided. The patient support may include a plurality of inflatable members. The plurality of inflatable members may include a core including a resilient material. The patient support may be controlled with a first controller positioned within an envelope of the patient support. The patient support may include a detector to detect when an external controller is coupled to the patient support, the patient support being controlled by the second controller when the second controller is present.

A reduced outflow valve in fluid communication with an inflatable apparatus comprising a tubular body defining an inner bore and a plunger slidingly engaged in the bore. Inflation of the inflatable apparatus urges the plunger to a first position configured to allow rapid ingress of air into the cushion to inflate the cushion and deflation of the inflatable apparatus urges the plunger to a second position wherein the plunger is configured as a baffle to dampen or slow air egress during release of air.

A bed system includes microclimate control capabilities for providing quality sleep experience. The bed system can include a microclimate control subsystem configured to supply conditioned air (e.g., heated or cooled air) to a mattress, or draw ambient air from the mattress, to achieve a desired temperature at the top of the mattress. Utilizing supply of conditioned air to provide air at desired temperature to the mattress system, or utilizing air suction to drain heat away from the mattress system, can provide precise microclimate control at the mattress, thereby permitting conformable sleep.

There is provided a bed device comprising: a support plate; a spring mattress provided on the support plate; a mat provided on the spring mattress; and a hot-air supply device for supplying hot air into the spring mattress, wherein the hot-air supply device is received in the spring mattress, wherein the hot-air supply device includes: a hot-air generation unit for generating hot-air; a hot-air discharge tube protruding from the hot-air generation unit by a predetermined length to discharge the hot-air generated in the hot-air generation unit into the spring mattress; and two hot-air guide members symmetrically disposed about the hot-air discharge tube, wherein the two air guide members are configured to guide the hot-air such that the hot air discharged from the hot-air discharge tube is distributed uniformly over an entire area of the spring mattress.

Adjustable mattress assemblies are described in which a mattress incorporates regions where additional pressure reduction is adjustable via pliable fluid bladders filled with a gas or fluid. Such areas of the mattress where additional pressure reduction is desired may include regions of the mattress which support areas of the body which may be particularly susceptible to pressure ulcers such as the heels, sacral regions, etc.
