The invention relates to a flexible member with adjustable stiffness for lying and/or sitting furniture. This member includes one or more inner spring(s) oriented along a central axis, one or more pair(s) of outer helical springs about the central axis, and a rotating part able to rotate, about the central axis, between a blocking position and an unblocking position. Each pair of outer helical springs includes an upper outer helical spring and a lower outer helical spring, connected by a corresponding hinge, which has a pivot axis orthogonal to the central axis. In the blocking position, the rails engage the corresponding hinges of the pairs of the outer helical spring, so as to prevent radial displacement, relative to the central axis, of the corresponding hinges, while the unblocking position allows the radial displacement of each corresponding hinge.

A polymeric material mixture comprising a fluorine-containing polymer, a siloxane polymer, and at least two polymer processing additives (PPA), wherein the at least two polymer processing additives have different chemistries. For example, there can be a flexible coextruded pipe for providing a protective housing for cables, fluids, sludge or solids, the pipe comprising a pair of telescopically related inner and outer layers, where said inner layer is lubricated with the polymeric material mixture.

An apparatus has a bed with bedding; an air mover; and an air outlet defined by the air mover to direct air into a sleep zone of the bed. A method includes operating an air mover to direct air into a sleep zone defined between a bed and bedding.

A pocket spring unit comprising a plurality of pocket springs each comprising a coil spring and a pocket. Each of the pockets comprise top portion and bottom portions. Each of the pockets are formed from a continuous top piece of fabric attached to a continuous bottom piece of fabric to form a bond having a plane perpendicular to the longitudinal axis of each coil spring. The pocket spring unit further comprises an attachment layer comprising a top portion comprising an inner and outer surface. The pocket spring unit further comprises a plurality of first cushion elements engaged with the outer surface of the top portion of the attachment layer. The inner surface of the top portion of the attachment element is engaged with the top portion of the pockets of the pocket springs such that each of the first cushion elements act only upon one of the pocket springs.

A self-adaption breathable cushion comprises a fixed base and a plurality of self-adaptive units integrated side by side and disposed on the fixed base; each of the adaptive units comprises a strap and an elastic member, the elastic member supports the strap to tension above the fixing, base, when the strap is pressed by the pressure and recessed downwards, the strap pulls the elastic member to be deformed, so that the self-adaptive unit moves downwards in a whole; when the pressure is removed, the elastic member is reset under its own elasticity, and the strap is also reset. The self-adaption breathable cushion can be self-adaptive deformed according to the weight of a human body to be borne, so as to be attached to the human body, making the human body more comfortable, ventilated and breathable, easy to clean, and inexpensive.

There is provided a bed device comprising: a support plate; a spring mattress provided on the support plate; a mat provided on the spring mattress; and a hot-air supply device for supplying hot air into the spring mattress, wherein the hot-air supply device is received in the spring mattress, wherein the hot-air supply device includes: a hot-air generation unit for generating hot-air; a hot-air discharge tube protruding from the hot-air generation unit by a predetermined length to discharge the hot-air generated in the hot-air generation unit into the spring mattress; and two hot-air guide members symmetrically disposed about the hot-air discharge tube, wherein the two air guide members are configured to guide the hot-air such that the hot air discharged from the hot-air discharge tube is distributed uniformly over an entire area of the spring mattress.

Mattresses and improved fabric covers for providing mattresses that have smooth surfaces. Additionally, methods for manufacturing non-quilted mattress covers and for manufacturing mattresses employing non-quilted mattress covers. The systems and methods described herein include mattress panels that can be manufactured separate from the inner core construction, and laid over the inner core to be fastened in place as a sleeping surface for the mattress. Optionally, these mattress panels can include a layer of fire retardant material, that may be added as a layer of material or that may be incorporated into one or more of the layers, such as a filler layer, in the mattress panel.
