An adjustable seat cushion. The adjustable seat cushion provides a frame defining an interface. The interface receives a plurality of dynamic supports and a plurality of static supports. The plurality of dynamic supports is disposed alternatingly between the plurality of static supports upon the interface. A handle is in operable connection with the plurality of dynamic supports. Rotation of the handle in a first direction elevates the plurality of dynamic supports relative to the plurality of static supports. Rotation of the handle in a second direction depresses the plurality of dynamic supports relative to the plurality of static supports.

An adjustable chair frame with a back and seating surfaces that flex to conform to the shape, weight and movement of an occupant is disclosed. The chair form and proportions provide for a recumbent position that disperses the weight of the occupant more evenly, thereby reducing external and internal physiological point loading. The form also provides ergonomic articulation to minimize internal physiological stresses such as neck/back vertebral compression. Eccentric connections driven by a motor assembly allow positioning adjustment of the components of the chair. Additionally, an air pump assembly may be included to automatically adjust one or more air bladders provided on the interior of the chair frame.

A method of using a seating device including a base, a plurality of roller mechanisms, a seat operably associated with the base via the plurality of roller mechanisms for movement relative thereto, the seat including a leading edge in a direction of travel, comprises receiving a user's sitting area on the seat of the seating device with the seat in a position centered over the base; and based on user input the seat moving toward the leading edge in the direction of travel away from the seat centered over the base while the user's muscles are engaged to maintain an upright posture, helping to improve the user's motor control, stability and strength over time.

A re-configurable item of furniture is provided, and includes at least a first reconfigurable portion having in turn a plurality of deformable cells, each having electrically operated valves to control a gas inflow to the respective cells from a gas inflow source, and a gas outflow from the respective cells, to thereby modify the pressure within respective cells. The gas inflow source includes a high-pressure reservoir cell among the plurality of deformable cells. The item of furniture also includes a control unit arranged to transmit control signals to a plurality of the electrically operated valves, including a valve of the high-pressure reservoir cell, to modify the pressure within a plurality of the cells in a coordinated manner selected to generate a new configuration of support for a user of the furniture.

A motion seat is described that includes a chassis, a seat frame, a seat cushion, a backrest, and a resilient hinge. The seat frame is attached to the chassis and the seat cushion and the backrest are each attached to the seat frame. The resilient hinge formed as a unitary body and may be formed from a resilient polymer. The seat cushion and/or the backrest is pivotably attached to the seat frame with the resilient hinge.

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 lounge having a matrix mat and a plurality of modules capable of being inserted into the matrix mat. The lounge may include a frame configured as a rigid frame, a modular frame, and combinations thereof. The modular frame may further include a tri-cable suspension. The tri-cable suspension may be attached to a dilator retractor mechanism. The modules may be a mushroom cap module, a spider spring module, a web module, a lighting module, an electronics module, and combinations thereof.
