An adjustable bed includes a frame structure; a plurality of platforms disposed on the frame structure; and an adjustable assembly coupled with the frame structure and the plurality of platforms for operably adjusting one or more of the plurality of platforms in desired positions; and an aromatherapy system attached onto the one or more platforms for producing desired fragrance in a surrounding space of the adjustable bed so as to promote health and well-being of a user. Each aromatherapy device is configured to produce a fragrance when said aromatherapy device is turned on, and one or more working modes. The fragrance is identical to or different from that produced by other aromatherapy device of the one or more aromatherapy devices.

An upholstered comfort member, comprising a resilient comfort material and a cover fabric. The resilient comfort material comprises lignocellulosic fibres, which provides resilient properties to the resilient comfort material, and a binder at a concentration of between 1 and 30 wt %. The binder binds the lignocellulosic fibres together. The invention further relates to a method for manufacturing of such an upholstered comfort member.

A seat back for an office chair includes a knit material for extending over a structural frame. The knit material can be formed in a single knitting operation to include cushioning characteristics that vary across different regions of the knit material. The knit material may be a weft knit material having a first layer, a second layer, and a third layer, wherein the third layer is inlayed between the first and second layers and the inlay material is different from at least the first and second layers and provides a degree of cushioning between the first and second layers. The first and second layers are knit according to a predetermined pattern, the predetermined pattern determining crossing lines where the first and second layers cross one another and fix the third layer in position with respect to the first and second layers. The predetermined pattern is differentiated between regions of the back support, such that a first region of the back support has a higher density of crossing lines than a second region of the back support, the first region providing a different degree of cushioning than the second region.

An assembly for removing liquid from bedding, including a liquid impermeable layer portion, a padding portion disposed adjacent the liquid impermeable layer portion, and a suction conduit array portion operationally connected to the liquid impermeable pad portion and disposed between the liquid impermeable layer portion and the padding portion. A vacuum source is operationally connected to the suction conduit array portion. A liquid trap portion is operationally connected between suction conduit array portion and the vacuum source portion. A urine sensor and an electronic controller may be operationally connected between the suction conduit array and the vacuum source.

Mattress assemblies that provide user comfort and increased airflow generally include a viscoelastic thermally conductive infused polyurethane foam top layer; a composite comprising a bottom layer, a molded viscoelastic middle foam layer, and a perforated top viscoelastic foam layer, wherein the molded viscoelastic middle foam layer comprises a plurality of interconnected substantially parallelpipedal bodies, wherein each parallelpipedal body includes an opening extending from a bottom surface to a top surface and is separated from an adjacent parallelpipedal body by a V-shaped notch, and wherein the perforated top viscoelastic foam layer comprises a plurality of perforations extending from a bottom surface to a top surface thereof, wherein at least a portion of the perforations overlies the opening in the parallelpipedal bodies; and a base core layer, wherein the composite overlies the base core layer.

The present invention discloses a multifunctional motion simulation bed which has multiple segments and simulates preprogrammed motions. The segments are articulately connected to form a motion platform. In one embodiment, the segments are disposed above a base. Actuators are mounted on the base and pivotally coupled with the base and the segments. A microprocessor drives the actuators individually and causes the motion platform to simulate motions. In another embodiment, the segments are disposed above a frame which is arranged above a base. One segment is fixed on the frame. Some actuators are pivotally coupled with the frame and some of the segments. Other actuators are pivotally coupled with the frame and the base. A microprocessor drives the actuators individually and causes the frame and motion platform to simulate motions.

A bed includes a mattress set on which a user's body is placed, an adjustable bedframe to adjust a position or orientation of the mattress set for various sitting and sleeping positions, 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 to reduce mildew and mites. 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 chair foot attachment for improving focus is a flexible hollow member having a height with side walls defining bottom edges of the hollow member and having an upper wall with a cavity extending downwardly into the hollow member from the upper wall. The cavity extends only partially into the hollow member and defines a cavity height that is less than the height of the hollow member. The cavity has an upwardly facing bottom surface for abutting a bottom of a chair foot when the chair foot is installed in the cavity. When a chair foot is positioned in the cavity, it permits an associated chair to wobble.
