A lumbar traction device for treating a lower back of a user includes a shell that is coupled to and extends from a rear edge of a panel. The shell and the panel are configured to position on a seat and in abutment a backrest of a chair, respectively. A coupling means that extends through a front of the shell is coupled to a plate positioned in the shell. The coupling means is configured to couple to a torso of the user to couple the user to the plate. An actuator, which is positioned in the shell and operationally coupled to the plate, is positioned to selectively raise the plate relative to the seat of the chair. The coupling means is configured to transmit an upward force from the actuator to the torso of the user to place a lumbar region of a spine of the user in traction.

There is provided a tactile presentation device capable of realizing easier wearing/removal and contact of a tactile stimulation unit in an appropriate position. The tactile presentation device is provided with an attaching unit to a back plate of a chair, and a wearing belt portion to a body provided so as to be extendable and contractable on the attaching unit, in which one or more first tactile stimulation units are provided on the attaching unit, and one or more second tactile stimulation units are provided on the wearing belt portion.

The invention relates to outdoor furniture having a seat cushion having a cover material on the bottom and back sides so that the seat cushion that can be turned over and flipped front to back to protect the cushion from weather outdoors. The frame includes a seat pan support for supporting a seat assembly. The seat cushion assembly has a cushioned first surface and a covered second surface. In use, the seat cushion assembly may be configured for protection or may be configured for seating by a user by flipping the seat cushion assembly over and by flipping the seat cushion assembly from front to back.

A backrest having features that support proper sitting posture of a user to improve back health and posture may be utilized. The backrest may include a front wall with wings extending to the left and right and diagonally forward to reduce Kyphosis of a user when sitting against the backrest. A combination of the front wall and wings may causing the user's (i) back ribs to be raised and gently tilted forward and (ii) thoracic spine region to be gently thrusted forward. By thrusting the thoracic spine region and raising and tilting the back ribs, a user's abdominal cavity may be expanded, and thereby reinforcing the ideal positioning of the cervical spine so that the user's head naturally positions on axis and does not “dump” forward.

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 buttocks elevating auxiliary seat cushioning system includes a chair having a seat and a backrest that is attached to and extends upwardly from the seat. The seat has an upper surface angled downwardly toward the backrest. A cushion assembly is positioned on the upper surface of the seat and abuts the backrest. The cushioning assembly has a top side, a front side, a rear side, a first lateral side, a second lateral side and a bottom side. The top side is angled upwardly from the front side to the rear side when the bottom side is abutted against the seat and the rear side is abutted against the backrest. The cushion assembly is resiliently compressible.

The present disclosure relates to configurable stacking chairs having a standard seat base frame design to which different interchangeable seat backs can be quickly and easily attached. The seat base frames and the interchangeable seat backs may include corresponding quick-connect features that allow selective attachment therebetween. The interchangeable seat backs may be attached to a standard seat base frame via a magnetic connection. Each interchangeable seat back can have a different unique design allowing for a quick change of appearance by exchanging one interchangeable seat back design for another. The interchangeable seat backs and the standard seat base frames can be stored separately and take up less space than completely assembled or fixed back chairs.

The present invention relates to a lumbar support for fastening to a backrest of a seat, comprising or consisting of a lumbar support body and a fastening strap fastened to at least two points on the lumbar support body, the fastening strap being of substantially inelastic form in a bracing direction, and the bracing length of the fastening strap being adjustable using at least one bracing means. The invention furthermore relates to the use of the lumbar support according to the invention with a backrest of a seat.

A rollable, lightweight compact cushion that may be attached to an object of different dimensions using the adjustable attachment apparatus. The outer covering of the cushion has a pocket incorporated in the outer covering that provides the user a small storage space to store objects. A loop is attached in a predetermined position to allow the user to hang small objects from the loop. An elasticized loop allows the user to easily roll up and secure the cushion in a compact position for ease of transport and storage. The stuffing material for the cushion is a biodegradable natural rubber latex foam free of added fillers and/or petroleum products.
