Abstract: A foam seating article includes an outer layer of molded foam surrounding a solid inner core of molded foam or expanded polystyrene. The rigid foam of the inner core is made from polyurethane polyol and methylene diphenyl diisocyanate (MDI). The inner core has a hardness greater than 25 Shore A and a density less than two pounds per cubic foot. The polymer material of the solid core has a hardness that is greater than that of the outer foam. The outer layer of molded foam is high density (HD) foam, memory foam or latex foam. A fabric covering encloses the inner core and molded outer foam layer. The foam seating article can be a chair, stool, sofa, chaise lounge, bench or Ottoman. The seating article includes no wood or metal. Molding foam around a solid inner core is simpler and less costly than making conventional metal or wood framed furniture.

Abstract: A foam seating article includes a layer of molded foam surrounding a hollow shell made of hard plastic. A fabric covering encloses the shell and molded foam. The foam seating article can take the form of a chair, stool, sofa, chaise lounge, bench or Ottoman. The hollow shell can be formed using blow molding, injection molding or by capping both ends of a tube with disks. Air pressure inside the airtight hollow shell prevents the shell from collapsing inwards under the weight of an occupant. Alternatively, the hollow shell of the seating article can be accessed through a removable lid. The seating article includes no wood or metal. The layer of molded foam includes sections of different foam types, such as high density (HD) foam, memory foam and latex foam. Molding foam around a hard plastic shell is simpler and less costly than making conventional metal or wood framed furniture.

Abstract: A collapsible beach chair includes upper tubes, leg tubes, a central tube connector, a seat back and a fabric support base. Lower ends of the upper tubes fit into upper holes in the tube connector, and upper ends of the leg tubes fit into lower holes in the tube connector. Upper ends of the upper tubes fit into first tube receptacles in the seat back, and ground ends of the leg tubes bit into second tube receptacles in the support base. The upper holes are disposed in an upper portion of the tube connector that swivels over a lower portion into which the lower holes are bored. The upper portion and the attached upper tubes swivel about a shaft that passes through the upper and lower portions but does not extend above or below the tube connector. The fabric support base prevents the leg tubes from sinking into the sand.

Abstract: A compact collapsible chair includes upper tubes, leg tubes, a central tube connector and a seat back. The upper tubes are formed from detachable sections. Lower ends of the upper tubes are inserted into upper holes in the central tube connector, and upper ends of the leg tubes are inserted into lower holes in the central tube connector. Upper ends of the upper tubes fit into tube receptacles in the seat back. No part of the upper tubes other than the upper and lower ends contacts any part of the collapsible chair. The upper holes are disposed in an upper portion of the central tube connector that swivels over a lower portion into which the lower holes are bored. The upper portion and the attached upper tubes swivel about a cylinder that passes through the upper and lower portions but does not extend above or below the central tube connector.

Abstract: An adjustable, collapsible mattress support for a box spring has cross bars with slidably connected sections. A first section of each cross bar is fixedly attached to a band that folds around the second section and slides along the second section. A bolt that passes through holes in the second section slides into a slot in the band. By aligning the slot over one of the holes through which the bolt passes, the length of the cross bars can be adjusted to accommodate the widths of different sized box springs and mattresses. The first section is fixedly attached to a hinge plate. First and second bars are pivotally attached to the plate. The first and second bars pivot about parallel axes that pass through the plate at separate fixed locations and that are orthogonal to the plate. The mattress support accommodates full, Queen, California King and Eastern King sized mattresses.

Abstract: A physiological sensor apparatus comprises a physiological sensor, a headband and an eye mask. In one example, the physiological sensor includes a plurality of electroencephalography (EEG) electrodes that are used to sense a signal indicative of a sleep stage (e.g., REM sleep or non-REM sleep) of a user. Each end of the headband attaches to respective ends of the sensor and eye mask such that when the sensor is disposed on the forehead of the user, the eye mask shields the eyes of the user from visible light. The diameter of the headband is adjustable by the user to secure the sensor to the forehead of the user. The sensor accurately determines the sleep stages of the user over a period of sleep of the user because the adjustable headband and eye mask prevent the electrodes from being displaced from the forehead of the user during the period of sleep.

Abstract: A method of making foam imparts antimicrobial and antiodorant qualities to the foam. Green tea powder is added to the polyol raw materials for making memory foam. The green tea memory foam is used to make pillows, cushions and mattresses. Green tea foam in the top layer of a mattress acts as an antiodorant such that less of the chemical smell of the memory foam is perceived by the user. In addition, the bacteria and mold that would otherwise develop in the moist warmer sleeping environment on memory foam are killed by the green tea additive to the foam. Measurable antimicrobial and antiodorant qualities in the green tea foam are achievable by adding green tea powder constituting less than 2% of the weight of the resulting green tea foam. A neck-support contour pillow is made using memory foam that contains green tea and a green dye.

Abstract: An assemblable mattress support can be shipped with all of its components compactly packed into the headboard. The mattress support includes a foldable longitudinal bar, a lateral bar, side panels, wooden slats, block legs and a footboard, all of which fit inside a compartment in the headboard. In an assembled state of the mattress support, a first connector at one end of the longitudinal bar attaches to a third connector on the outside of the headboard. A second connector at the other end of the longitudinal bar attaches to a fourth connector on the footboard. The middle of the lateral bar connects to the middle of the longitudinal bar. The block legs are attached to the bottom sides of the headboard and footboard. The slats are attached to one another by fabric ribbons and are placed in parallel over the longitudinal bar and support ledges on the side panels.

Abstract: A foldable mattress support has an adjustable inner frame with a ratchet support for raising the head of a mattress. Legs are incorporated into the side and end bars of the mattress support. Upper and lower bars of the support are pivotally attached to the vertical plate of a hinge. Bolts oriented along axes of rotation pass through the bars and through the vertical plate. A first upper bar pivots about a first axis; a second upper bar pivots about a second axis; a first lower bar pivots about a third axis; and a second lower bar pivots about a fourth axis. Each of the axes is orthogonal to the vertical plate, and the third axis is spaced farther apart from the fourth axis than the first axis is spaced apart from the second axis. The distal ends of the upper and lower bars are pivotally attached to end bars.

Abstract: A massaging floor mat includes a layer of gel that penetrates into the cells of a layer of memory foam. The layer of foam sits on a foundation layer of hard plastic. A plurality of protrusions are distributed over the upper surface of the foundation layer. The protrusions provide a massaging sensation to the user of the mat. The protrusions also hold the layer of foam in place obviating the need to glue the foam to the foundation layer. The gel is spread over the foam as the foam moves along a conveyor belt. The gel is then cured using hot air. The foundation layer is held in place in an indentation of a bottom cover of flexible plastic without using any glue. A top cover is placed over the layer of gel, and the peripheries of the top and bottom covers are attached to each other using high-frequency welding.
