An air-supply device (1) for supplying breathing air into a breathing-air region (2) has at least one inflow opening (4, 6) for supplying breathing air, and also has an interior (10) and at least one outflow region (11), via which breathing air flows out into the breathing-air region (2). The inflow opening (4, 6) is connected to the outflow region (11) via the interior (10). The outflow region (11) is connected to the outflow region (11) via the interior (10). The outflow region (11) is formed on a flexible, air-permeable material (12). In order to provide for flexible use of the air-supply device (1) and to avoid any significant adverse effect to a user, provision is made for the air-supply device (1) to have a sheet-like, flexible portion (16), which has a first flat side (7) and a second flat side (8), located opposite the first. The outflow region (11) is arranged on the first flat side (7). The interior (10) is formed between the first flat side (7) and the second flat side (8). In the interior (10), at least the outflow region (11) has arranged on it at least one spacer, which prevents the outflow region (11) from butting against the second flat side (8).

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.

A mattress core includes sandwiched layer of coils that includes coils disposed between a first spacer fabric layer and a second spacer fabric layer. The mattress core also includes a viscoelastic foam disposed beneath the sandwiched layer of coils. A top surface of the first spacer fabric layer is disposed at or adjacent to a top surface of the mattress core. The first spacer fabric layer defines or more first air channels and the second spacer fabric layer defines one or more second air channels. The one or more first air channels extend above the coils included in the sandwiched layer of coils and the one or more second air channels extends below coils.

A combined and/or composite resting structure comprising a mattress suitable to be normally disposed on a net anchored to a support structure to define a bed on which a person sleeps or rests and at least one mattress cover coupled on top of the mattress through a connector. In particular, the mattress cover comprises at least two padded linen items, facing and opposite each other and mutually connected through a main junction in such a way as to define between the linen items at least one hygroscopic interstitial air chamber which identifies a free volume and is suitable for imparting breathability and thermoregulation to the combined resting structure.

A speaker system includes a cushion body with which a person comes into contact when sitting therein, and a speaker, a front of which is covered by the cushion body. The cushion body includes: a three-dimensional mesh-like elastic part that is formed by a three-dimensionally entangled fiber and bears a load of the person; and a cover member that covers surroundings of the three-dimensional mesh-like elastic part. The cover member includes a first cover member that covers the part of the surroundings of the three-dimensional mesh-like elastic part located at the front of the speaker, and a second cover member that is a remainder of the cover member excluding the first cover member. The first cover member has a higher acoustic transmissivity than the second cover member.

A bedding includes: a cushion layer which is formed with a filament three-dimensional bonded member and which is breathable; a breathable water-repellent layer which is provided on the upper side of the cushion layer and which is breathable and water-repellent; and a breathable water-retentive layer which is provided on the upper side of the breathable water-repellent layer and which is water-retentive and is breathable during water retention.

A body support cushion is provided with layered foam which receives airflow and allows passage in predefined areas through the body support cushion. Additionally, a cover is provided including a spacer fabric that allows air movement from the body support cushion to improve ventilation of the user of the cushion.

A body support structure including a backrest, a seat connected to the backrest, and a suspension material connected to the backrest or the seat. The suspension material includes elastomeric filaments with monofilaments and multifilaments. The suspension material further includes a first zone with a first stiffness, a second zone with a second stiffness greater than the first stiffness, and a transition zone positioned between the first zone and the second zone.

A mattress topper for providing improved comfort to a sleeper comprises a pressure distribution layer defining an interior volume. The pressure distribution layer has substantially air-impermeable side walls and a substantially air-impermeable base, and a top surface having at least a region that is air permeable. Support material is contained within the interior volume. The mattress topper includes at least one electrically powered air circulation device for drawing air into the interior volume of the pressure distribution layer via at least one air inlet port. A lateral air-flow layer is disposed above the pressure distribution layer and is configured to provide substantially unimpeded air flow both upwardly and laterally.

A bedding includes a surface cushion member which has air permeability in the thickness direction and the plane direction and whose surface side is a contact surface, and thereunder, a bed internal environment control means which forms a stream of air in the surface cushion member. In the surface cushion member, air passes through the thickness direction and quickly spreads in the plane direction, and an air layer in the surface cushion member is controlled to a predetermined temperature, humidity, or air flow, to generate the temperature gradient, the humidity gradient, or the air flow gradient between an air layer supported by the surface cushion member and the air layer in the surface cushion member.
