A spine-protecting and spine-correcting multi-functional health-care seat device employing gravity to achieve embrace-like support, pressure reduction, fixing, and correction, including a seat frame and a gravity embrace-like support and sitting device. The gravity embrace-like support and sitting device includes a sitting plate (1), sitting plate support rods (8) symmetrically arranged on two sides of a bottom of the sitting plate (1), rotating bearings (1101) symmetrically arranged on two sides of the seat frame, embrace-like support levers cooperatively arranged on the rotating bearings (1101), and embrace-like support palms (2) arranged at top ends of the embrace-like support levers. One end of each sitting plate support rod (8) is hinged to a bottom of the sitting plate (1), and the other end is hinged to a bottom of each embrace-like support lever through a support rod rotating shaft (15).

A seating arrangement includes a base, a seat assembly operably coupled to the base, and a back assembly that includes a substantially rigid back frame including a pair of side portions spaced from one another and extending upward from the base, and a substantially flexible back shell including a front surface and a rear surface opposite the front surface, a plurality of laterally-extending slots that extend between the front surface and the rear surface and that cooperate to define a plurality of laterally-extending ribs therebetween, where a pair of laterally-extending ribs of the plurality of laterally-extending ribs are connected to one another via a vertically-extending rib located at a substantial midpoint across a width of the back shell, and wherein the back shell is coupled to each of the side portions of the back frame at locations above the plurality of laterally-extending slots.

An article of furniture has retractable and extendable wheels secured beneath each leg. The mechanism for retraction and extension is accomplished by an activation means in mechanical communication with each wheel.

A seating apparatus for supporting a portion of a user, the seating apparatus comprising a reorientable seat portion including a seat platform and a cutout, wherein the seat selectively underlies a first ischial tuberosity of the user but not the second ischial tuberosity, the selection of which is determined by the orientation of the reorientable seat portion.

An apparatus that supports a user in a variety of positions to comfortably perform tasks, such as applying one or more tattoos to skin of a subject is herein disclosed. The apparatus can be reconfigured to optimally position and support the arms and/or chest of the user. A method for using a stool can involve rotating armrests of the apparatus from a stowed position to a deployed position. The armrests can support the user's forearms while supporting the user's chest such that the user can comfortably perform tasks in front of a chest support of the stool.
