A posture improvement assembly includes a base that has a top side and a bottom side and is elongated from a first lateral edge to a second lateral edge. A panel has a top edge and a bottom edge wherein the bottom edge is attached to the top side of the base and extends upwardly therefrom. The bottom edge is oriented parallel to a longitudinal axis extending through the first and second lateral edges. The panel lies in a plane orientated perpendicular to a plane of the bottom side of the base. The panel is telescopic and has an adjustable height. A locking member is mechanically coupled to the panel and releasably locks the panel at a selected height. A cushion is attached to and covers the top edge. The base is positioned on a chair to allow a person to place their back against the panel.

A system and method of use for a portable backrest that is collapsible having a frame supported by a base with adjustable backrest portions pivotally attached to the chair whereby when a user's wishes to use the backrest in an inclined position with their supported, they incline the backrest members which will position the user in the most optimal position relative to the sun for sun bathing whereby the user may collapse the backrest and then move it to another location with an attached strap. The backrest may also have other uses such as a table or platform while at the beach.

A portable mattress seating apparatus attachable to a mattress. The portable mattress seating apparatus clips onto a location on the peripheral of any conventional mattress. The apparatus has a retaining member that is retained under a mattress and above the box spring. The retaining member is attached to a vertical member adjacent to the side of the mattress. The vertical member is attached to another seating member that is oriented parallel to the top of the mattress face. The seat member is attached to a back-rest member. The back-rest member is attached to the seating member distal to the side of the mattress. The back-rest member is adjustable, allowing the back rest to be at acute, obtuse or 90-degree angles to the seating member. Further, the apparatus includes supporting members to spread the weight of a seated person.

The lumbar support assistive device includes a plastic rigid main member having a half-fusiform whose front side curves in accordance with human spine. A trough is provided along the front side extended in an axial direction to a bottom side of the main member. A number of forward bulging semi-ellipsoidal elements are arranged at intervals in two columns along lateral sides of the trough. The semi-ellipsoidal elements closer to a bottom of the main member are wider and higher; and the semi-ellipsoidal elements closer to a top of the main member are narrower and lower, and they are closer to the semi-ellipsoidal elements in the other column These semi-ellipsoidal elements provide massaging effect and support to corresponding intervertebral discs of the spine. The semi-ellipsoidal elements also raise the lumbar support assistive device to provide enhanced ventilation so that wearing the lumbar support assistive device would not feel sultry.

A side pillow support device is provided which utilizes a bottom surface having a front planar bottom surface and a rear planar bottom surface. The front planar bottom surface is separated from the rear planar bottom surface by a beveled bottom surface. The rear planar bottom surface is entirely disposed above the front planar bottom surface and the front planar bottom surface terminates into a front lip. The device further utilizes an inner support surface disposed between left and right side cushions. The inner support surface utilizes a concave shape and a front portion of the inner support surface terminates into the front lip.

A backsaving device having a main body sized and shaped to corresponding to the height of an under-sink cabinet, such that when the backsaving device is disposed adjacent the under-sink cabinet, a top surface of said main body is generally coplanar with a bottom interior of said under-sink cabinet. This allows a worker working under the sink to lay back on the device comfortably without the edge of the cabinet digging into the back or shoulders. A rotatably flip may be used to bridge the gap between the device and sink to prevent pinching.

The self-adjustable backrest device supplements a seat surface such that said seat surface is a previously existing one and what is covered by the object of this invention adds a backrest or improves the existing one, for which purpose it comprises a mobile plate on which the user rests, wherein said plate swivels on a horizontal shaft that passes through a first set of hubs connected to the plate, that shaft being associated with a second set of hubs connected to a support that may be the backrest itself of the chair or easy chair on which the self-adjustable backrest is going to be used, in which case it will be referred to as pre-existing backrest, or it may be a fixed backrest which forms part of the device, in which case it will be referred to as backrest of the device. The device may include fixing elements to prevent its movement, such as legs, pegs, or a flap.

A rebounding device includes a front member, a rear member, and a spring mechanism including a first biasing element and force adjustment assembly. The force adjustment assembly includes a spring element including a front planar surface and a rear planar surface connected at a rounded portion, wherein the front planar surface contacts an inner surface of the front member; a screw housing secured to an inner surface of the rear member, wherein the screw housing includes a longitudinal channel and a bore on an upper surface; a drive screw positioned through the bore and along the longitudinal channel of the screw housing; a threaded block positioned within the longitudinal channel of the screw housing, wherein the threaded block is configured to move vertically along the longitudinal channel, and wherein the rear planar surface of the spring element is secured to the threaded block.

A back support apparatus for applying a support force to a user's back by using the user's knees while in a seated position including a back support member having a first end and an opposing second end, a pair of adjustable strap members coupled to and extending from the first and second ends of the back support member, and a pair of force distributing knee pads slidably coupled to the pair of adjustable strap members, the force distributing knee pads configured to receive the user's knees and to distribute a force applied by the pair of adjustable strap members along both horizontal and vertical planes, wherein a first adjustable strap member and a first force distributing knee pad is placed around the user's first knee, and a second adjustable strap member and a second force distributing knee pad is placed around the user's second knee, and wherein the support force applied by the back support member onto the user's back is generated by adjusting a length of the first and second adjustable strap members.

A rebounding device includes a front member, a rear member, and a spring mechanism including a first biasing element and force adjustment assembly. The force adjustment assembly includes a spring element including a front planar surface and a rear planar surface connected at a rounded portion, wherein the front planar surface contacts an inner surface of the front member; a screw housing secured to an inner surface of the rear member, wherein the screw housing includes a longitudinal channel and a bore on an upper surface; a drive screw positioned through the bore and along the longitudinal channel of the screw housing; a threaded block positioned within the longitudinal channel of the screw housing, wherein the threaded block is configured to move vertically along the longitudinal channel, and wherein the rear planar surface of the spring element is secured to the threaded block.
