A chair includes a base structure, a seat support structure, a back frame comprising a front surface, a rear surface and a forwardly extending bottom portion pivotably connected to the base, a biasing member biasing the back frame from a reclined position toward an upright position, wherein the biasing member is located entirely forward a rearward most edge of the seat support structure, and a back shell comprising a forwardly extending bottom portion connected to the seat support structure, a front surface, a rear surface positioned in front of the front surface of the back frame, a pair of laterally spaced side portions defining an opening therebetween, and a top portion extending laterally between and connected to the side portions, wherein each of the side portions are exclusively connected to the back frame at a first location.

A body support assembly includes a seat assembly and backrest assembly supported by tilt control assembly. Methods of using and assembling the body support assembly are provided.

A toting apparatus can include a bucket, a combination lid and seat cushion, and a harness for carrying the apparatus while the lid covers the top opening of the bucket and the cushion is in the inflated or deflated configuration. The cushion can be formed by a drop-stitch type bladder inflatable using a common hand-operated bicycle pump. The harness can include a belt that wraps around the bucket and a pair or diametrically spaced-apart straps that adjustably and snuggly attach to a central handle structure atop the lid. Various corresponding patches of hook-and-vane style fabric fasteners allow for releasable affixation of various components of the apparatus. Thus the harness can be made of durable flexible fabric.

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.

A bag includes a main compartment configured to accommodate equipment, and a foldable chair compartment disposed adjacent to the main compartment. The foldable chair compartment is configured to accommodate a foldable chair in a folded configuration.

An adjustable support for differentially adjusting the height of a user's ischial tuberosity to relieve pain from sitting is disclosed. The support includes an adjustable left and right platform, each including at least one stackable lift having a stiffness sufficient to provide pressure to lift the sitz bone(s). Each lift is shaped and sized so that it can be securely stacked on top of the other. The stackable lifts may be connected along an inner edge in a hinged manner or can be received within at least one pouch and movable between the left and right platforms. To lift the height of the lower sitz bone the right and left platforms have a differential height between them, determined by the amount of adjustment needed. The differential adjustable seating height creates a counterbalancing repositioning of the sitz bones relieving the asymmetrical pressure of the sacral/lumbar complex caused by misalignment.

The present invention relates to seat systems, and more specifically to seat systems suitable for supporting users sitting in a cross-legged or kneeling position during activities such as meditation. Sitting closer to the ground, cross-legged, and/or kneeling enables the brain to easily enter a parasympathetic mode, providing users of the seat system a greater sense of calmness. The Multi-Angle Knee blocks (MAKs) offer a greater level of hip support for users.
