Disclosed are connectors and collapsible bed frames. A collapsible bed frame includes lateral and longitudinal bar units. Between each of two adjacent lateral bar units, a first longitudinal bar unit is disposed at a first side of the collapsible bed frame and a second longitudinal bar unit is disposed at a second side of the collapsible bed frame. The first and second longitudinal bar units and the two adjacent lateral bar units are rotatably connected with each other by connectors that enable the collapsible bed frame to contract and expand while the lateral and longitudinal bar units are connected with each other.

Disclosed are collapsible beds and bed frames. A collapsible bed frame includes first and frame units disposed side by side and connected with each other at their proximal sides. Each of the first and second frame units comprises a plurality of bar units. Adjacent bar units are connected with each other and rotatable with respect to each other along one or more axes each substantially perpendicular to a first plane defined by a top surface of the collapsible bed frame when it is expanded. The first and second frame units can contract and expand while remaining on the first plane and while connected with each other.

A collapsible bed frame includes a first lateral bar unit, a second lateral bar unit, and a longitudinal supporting bar unit. The first and second lateral bar units are disposed substantially parallel to each other. The first lateral bar unit includes a first coupler to removably couple with a first end of the longitudinal supporting bar unit. The second lateral bar unit includes a second coupler to removably couple with a second end of the longitudinal supporting bar unit. The collapsible bed frame also includes first and second longitudinal bar units. The first longitudinal bar unit is rotatably connected with the first ends of the first and second lateral bar units. The second longitudinal bar unit is rotatably connected with the second ends of the first and second lateral bar units.

A collapsible bed frame includes a plurality of lateral bar units, a plurality of first longitudinal bar units, and a plurality of second longitudinal bar units. The plurality of lateral bar units includes first and second outer lateral bar units and at least one inner lateral bar unit. A collapsible bed frame also includes a plurality of first connectors, each having a body and a supporting piece. The body is fixedly connected with an end of the first or second outer lateral bar unit, and the supporting piece is rotatably connected with an adjacent first or second longitudinal bar unit. The collapsible bed frame can contract and expand while the lateral and longitudinal bar units are connected with each other.

Disclosed are connectors and collapsible bed frames. A collapsible bed frame includes first and second frame units disposed side by side. Each of the first and second frame units comprises a plurality of bar units with adjacent bar units rotatably connected with each other. A collapsible bed frame also includes an inner lateral bar unit disposed between the first and second frame units, and rotatably connected with the first and second frame units. During contraction and expansion, the first frame unit, the second frame unit and the inner lateral bar unit remain substantially on a first plane defined by a top surface of the collapsible bed frame when it is expanded.

A metal seat stretcher that is configured for easy mounting to the seat box, and furniture items including the same. The disclosed stretcher may be mounted in such a way so as not be directly mounted to the forward or rearward rails, thus preserving the strength and integrity of the rails by not subjecting them to perforation from a multitude of staples. Instead, the front end of the metal seat stretcher mounts to a clip rail that is secured to the inside of the front rail, and back end of the stretcher is secured to a seat back upright. In some embodiments, securing of the disclosed seat stretcher is done with a single screw at the front end and a single self-tapping bolt at the back end (though more fasteners may also be utilized). This provides for rapid and easy assembly of the furniture item.

A bed system includes microclimate control capabilities for providing quality sleep experience. The bed system can include a microclimate control subsystem configured to supply conditioned air (e.g., heated or cooled air) to a mattress, or draw ambient air from the mattress, to achieve a desired temperature at the top of the mattress. Utilizing supply of conditioned air to provide air at desired temperature to the mattress system, or utilizing air suction to drain heat away from the mattress system, can provide precise microclimate control at the mattress, thereby permitting conformable sleep.

Reinforcement straps are used to hold a mattress system in place and keep it from bowing outwards when used. The mattress system can include a layer and a rail structure attached to the layer. The layer can have a layer top and a layer bottom opposite to the layer top. The layer can extend between a first layer edge and a second layer edge.

Devices and methods for determining item-specific information for single or multiple items on one or multiple substrates are described. The method includes generating multiple sensor multiple dimensions array (MSMDA) data from multiple sensors, where each of the multiple sensors capture sensor data for one or more items in relation to a substrate. For each item, the method includes determining relationships between the multiple sensors based on characteristics of the MSMDA data, determining a location of the item on the substrate based on at least the determined relationships between the multiple sensors, determining an angular orientation of the item on the substrate based on at least the determined relationships between the multiple sensors, and determining a body position of the subject on the substrate based at least the determined relationships between the multiple sensors, the location of the subject, and the angular orientation of the item.
