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.

Bedding components generally include a desiccant applied or infused into a selected bedding component. The desiccant can be microencapsulated, applied as a topical solution, and/or provided within a container including a moisture permeable membrane.

Aspects herein are directed to systems and methods for synchronization of actuators to reposition furniture units. Specifically, a master control box receives input to reposition a furniture unit from one position to another and communicates the input to a plurality of control boxes. Then, each of the plurality of control boxes assigns a virtual axis to each of a plurality of actuators attached to each associated control box. Furthermore, each of the plurality of control boxes assigns a transfer function to each of the plurality of actuators. The transfer function is used by the actuators to transform an output of the virtual axis to determine a target position. In this way, the plurality of actuators can reference the same virtual axis for synchronization purposes, but use different transfer functions to maintain complex relationships between the positions of each actuator. Based on the target position, the actuators reposition the furniture unit.

A bed device includes: an operation section that receives an operation input; a controller that controls a movement of the bed in accordance with the operation input; a detector that detects a position of a patient on the bed; and, a limitation table that stores a limitation area set on the bed in association with a limitation content, wherein when the position of the patient detected by the detector is included in the limitation area, the limitation content is read out from the limitation table so as to control the controller in accordance with the limitation content. With this configuration, it is possible to provide a higher safety bed device which can not only notify the danger based on the bed movement but also limit the movement of the bed in accordance with the status of the patient or the bed device.

A method of installing an array of linear foam strips designed to be vertically stacked with their linear axes parallel and vertically aligned under a region of a mattress that requires a raised contour on its top face to alleviate a medical condition or to repair a sag in the mattress. The foam strip arrays come in 24 or 32 inch lengths to correspond to the width of standard mattress. Each linear foam strip has a different width but none of the strips are within 25% of the width of any other foam strip. The widths of the four different foam strips in the array has been carefully sized to allow the best possible combinations to develop the proper height and side slope of the contour developed in the mattress's top face.

The invention relates to an electromotive furniture drive for adjusting movable furniture parts (5, 6) of an item of functional furniture (1), having a control device (9), at least one adjusting drive (7, 8) with an electric motor, and at least one evaluation circuit (10) with an input (11, 12), which evaluation circuit can be electrically conductively connected to a sensor, which is attached to the item of functional furniture (1), and forms a proximity and/or contact detector together with said sensor. The electromotive furniture drive is distinguished in that at least two proximity and/or contact detectors are formed by in each case one sensor or a group of sensors together with the at least one evaluation circuit (10), it being possible for said proximity and/or contact detectors to be assigned to different moving furniture parts (5, 6) of the item of functional furniture (1). The invention further relates to an item of functional furniture (1) having at least two groups of movable furniture parts (5, 6) and an electromotive furniture drive of this kind.

An antimicrobial article in the form of a portable hygiene mat. The mat includes a lightweight, flexible incorporated with an antimicrobial agent. The mat is readily configurable to a compact size. A fastener secures the mat in the compact configuration.

An operating system (10) for operating an article of furniture (12), the article of furniture (12) comprising a support structure, at least one component displaceably arranged relative to the support structure and a receiver. The operating system (10) includes a (controller 34) which communicates wirelessly with the article of furniture (12), the controller (34) outputting operating signals (46) containing operating instructions. A signal processing module communicates with the wireless controller (34) via a routing arrangement (48), the signal processing module receiving the operating signals (46) and converting the operating signals into control signals to be provided to the receiver to effect displacement of the at least one component of the article of furniture (12) relative to the support structure under the control of a user.

A modular furniture assembly includes: a base member having a frame assembly, a transverse member having a frame assembly, a foot configured to contact a support surface, and a mounting platform having a plurality of apertures therethrough. The mounting platform is configured to be mounted on the base member frame assembly and the transverse member frame assembly, thereby connecting the frame assemblies. The foot is selectively mounted on the mounting platform, such that the foot is configured to contact the support surface when the modular furniture assembly is in an upright configuration. The mounting platform connects the base and transverse member frame assemblies together and also acts as a platform for receiving a variety of different types of feet.
