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 bed includes components to control pressure of a sleep surface, for example based on sleep position and sleep stages of a user. In some embodiments target pressures for the sleep surface are iteratively adjusted over multiple sleep sessions so to achieve improvements in sleep states and/or sleep quality for the user.

In some embodiments, a support structures can be formed from a support structure matrix comprising a plurality of spring structures embedded within the support structure matrix. The plurality of spring structures can be formed from the same material or a different material, and can have the same or different durometers. The plurality of spring structures can be configured to deform and return to its original shape after deformation. The orientation and structure of the spring structures can vary depending on a desired durometer and/or function within the support structure.

According to the present invention, we present a system employed in the manufacture of furniture requiring plastic fabric rotary assembly meshes comprising a plurality of parts that can be used repeatedly, as all of them are made up of first male locking elements and second female locking elements that do not require extraneous fastening elements for their placement.

A sofa bed has a seat portion, a backrest portion and a hinge mechanism including a first section, a second section and a third section sequentially and pivotably connected. The first section is fixed to a side of the seat portion. The second section is fixed to a side of the backrest portion. A protruding portion is provided at a position where the first section is connected with the second section. Each of the armrest frames is formed with a slideway for receiving and guiding the protruding portion. An end of the third section opposite to the second section is pivotally connected to the armrest. The first section and the second section are be lockable to place the main body frame into a sofa configuration. The sofa bed can be easily switched between sofa and bed positions.

A cellular furniture construction system that includes: a set of voxels, that form a lattice providing the shape and structure of the furniture construction, wherein regions of the furniture construction comprise distinct three-dimensional lattice arrangements of different types of voxels, providing distinct stress/strain properties to the regions; wherein each voxel comprises: a voxel type, defined by the stress and strain property of the voxel, and a discrete cellular three-dimensional structure, enabled to connect with other voxels along any one of the voxel interface surfaces. The system functions as a lightweight, modular, furniture construction system, wherein the system leverages arrangements of different voxel types to construct a furniture structure with desired stress/strain properties to regions of the structure.

A bed includes a mattress set on which a user's body is placed, an adjustable bedframe to adjust a position or orientation of the mattress set for various sitting and sleeping positions, and a dryer to dry the mattress set. The dryer includes a fan, a filter, and a heater to discharge filtered hot air toward the dryer to reduce mildew and mites. A humidity sensing sheet may be provided to sense a humidity level at different regions or areas of the bed, and the dryer may be controlled to supply hot air to regions of the bed having a higher humidity level than a predetermined humidity level or humidity range.
