A baby sleeping cushion and method of use thereof, wherein the cushion is wedge-shaped and comprises two principal layers, a top layer and a bottom layer. The bottom high-density foam provides a firm backing or support and the selected elevation from head end to foot end. The viscoelastic or visio memory foam top layer molds to the body form of a baby, retarding lateral movement of the baby, and preventing the baby from rolling from side-to-side. In addition to the two-layer wedge-shaped cushion, a separate cushioning device, generally hemispherical in shape, is removably secured to the wedge-shaped cushion, and supports the baby's legs and buttocks; thereby preventing movement of the baby in response to the inclined slope of the wedge-shaped cushion. An additional embodiment provides a support pillow to restrain the baby's head from movement removably-secured to the wedge-shaped cushion.

An inflatable bed assembly having a plurality of inflatable cushion cells disposed on the top of the inflatable bed. Each cushion cell has a vent fluidly interconnecting the interior volume of the cushion cell with a main air chamber of the bed. When the bed is inflated, the cushion cells inflate and form raised projections on the top of the bed. The cushion cells provide a pressure sensitive surface which molds to the user's body for increased comfort. The vents are sized to allow the cushion cells to inflate upon inflation of the main air chamber, partially deflate when pressure is applied, and re-inflate when the pressure is removed. The size of the vents dampens the rate that air passes through the vent. The controlled inflation and deflation of the cells softens the impact caused by application of a body thereon and simulates the dampened response of “memory-foam”.

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.
