A layered cushion that may be fully disassembled for easy cleaning is disclosed herein. The sleep system is durable and fire retardant. The layered cushion may include a foam layer, a layer of void cells, and a cover. The foam permits fluids to move freely there through and contours to a user's body to maximize comfort and reduce interface pressure. The reticulated foam layer resists compression set and thermosetting. The layer of void cells also permits fluids to move freely there through and provide additional support to the user's body. The individual void cells of the void cell layer are perforated to allow the transmission of fluids there through. The cover couples the other layers together to form the layered cushion and prevents the layers from deteriorating. The cover is removable to permit cleaning each of the layers independently.

A chair assembly includes a seat support structure, a back support structure, a back tensioning assembly adjustable between low and high tension positions, an actuator assembly adapted to adjust the back tensioning assembly between the low and high tension positions, a control input assembly actuable by rotating the portion of the control input assembly, and a control link assembly operably coupling the control input assembly with the actuator assembly to adjust the back tensioning assembly between the low and high tension positions upon rotation of the portion of the control assembly by a seated user, wherein a number of rotations of the portion of the control input assembly is not limited by the control link.

Filament winding or another technique can be used to create composite parts having various layers of pigmented fibers. The composite parts can then be milled to form one or more flat surfaces on the composite part. Due to the layering of pigmented fibers, the flat surfaces can have a pattern that resembles wood grain or another pattern. These milled composite parts can then be used as components for furniture or other items.

A method for the production of a piece of furniture such as a seat, a bed, a table, the piece of furniture including at least one furniture component (10), the method including the steps of making a blank (11) of expanded polystyrene (EPS) with density between 15 and 25 kg/me, the blank (11) being configured to act as a core for the furniture component (10); providing an interface surface (12) in the blank (11); making a rigid insert (13) in rigid material having an engagement portion (14) configured to engage with the interface surface (12) of the blank (11) and a first connection portion (15) opposite the engagement portion; joining the rigid insert (13) and the interface surface (12) so that the engagement portion (14) is engaged with the interface surface (12) and the first connection portion (15) faces aside opposite to the blank (11); coating the blank (11) and the rigid insert (13) by at least one coating layer (30) of polyurethane material, so that the coating layer (30) completely covers the blank (11) and the insert (13), with the exception of at least one part (16) of the first connection portion (15).
