A humidity sensing sheet may be provided to sense a humidity level at different regions or areas of the bed, and the dryer may be controlled to supply hot air to regions of the bed having a higher humidity level than a predetermined humidity level or humidity range.

A bed according to an embodiment may include a topper, at least one firmness adjuster provided under the topper, and a bedframe configured to have an adjustable position and to support the firmness adjuster. There may be a plurality of firmness adjusters corresponding to a plurality of areas of the bed, and each firmness adjuster may include a plurality of cushions provided in a cushion case and a drive to adjust the firmness of the plurality of cushions. The drive may change a position of a first spring relative to a second spring in each of the cushions to change a perceived firmness by a user lying on top of the topper and the firmness adjusters. A dryer may be provided under the bedframe to keep the cushions and topper dry.

A spring module includes a spring and a spring bracket for accommodating the spring. The spring bracket may have a base, an end cover and a flexible connecting part connecting the base and the end cover. The spring may be fixed in the spring bracket with a predetermined initial pressure. The spring module may be used in a spring cushion for furniture.

A piezoelectric adaptive mesh includes multiple piezoelectric fibers that include piezoelectric structures that can act as sensor and/or actuators to enhance a person's comfort. The piezoelectric structures communicate with a controller and/or a software processing system and may identify the position of a user and make adjustments through the actuators to increase user comfort by providing support, assistance, treatment, and/or temperature adjustment.

A bed includes a mattress set, an adjustable bedframe to adjust a position or orientation of the mattress, and a dryer to dry the mattress set. The dryer includes a fan, a filter, and a heater to discharge filtered hot air toward the dryer. A humidity sensing sheet may be provided to sense a humidity level at different regions or areas of the bed, and the dryer may be controlled to supply hot air to regions of the bed having a higher humidity level than a predetermined humidity level or humidity range.

Adjustable sleeping system with massage function. At least one example embodiment is a method of operating a sleeping system, the method including massaging a person residing on a sleeping surface of the sleeping system, the massaging by driving a plurality of adjustable spring assemblies, the plurality of adjustable spring assemblies part of an array of adjustable spring assemblies arranged such that a top of each adjustable spring assembly defines an upper surface parallel to the sleeping surface.

A method of assembly and a product upon which a person may lie down that includes a mattress cover fitted onto a mattress cover to envelop same. The underside of the mattress cover has a projecting lip that bounds a recessed cavity that accommodates an adjustable mechanism, which is actuated to raise of lower head or foot portions of the mattress. The lip contains filler material such a foam and overlaps sides of the adjustable mechanism to conceal same.

A sofa bed includes: a plurality of elastic modules; a body frame having slide rails arranged thereon; and armrest frames disposed at two sides of the body frame along a longitudinal direction of the body frame, respectively. The slide rails on the body frame are configured to enable the plurality of elastic modules to be mounted on the body frame from an outside of the body frame and to slide thereon to predetermined mounting positions, such that the body frame at one side facing the user is provided with the plurality of elastic modules. The angle between the seat and the backrest portion can be locked for improved operation. The elastic modules, which can be easily installed and uninstalled, can improve the comfort of the sofa bed.

A three dimensional mattress system with environment control is provided which may be configured to provide three dimensional body support to a user. In some embodiments, the system may include a rigid frame that may form a frame cavity. Optionally, the system may include one or more temperature regulators. A plurality of pillows may be positioned within the frame cavity, and a user may be supported by the plurality of pillows. Optionally, one or more air moving devices may be configured to move air external to the frame through the plurality of pillows, and one or more air filters may be configured to filter air moved by the air moving devices.
