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.

A beam seating assembly has a frame supporting a seating surface. A beam secures to a first support and extends in a longitudinal direction. A channel is located the beam free of the first support. The frame has a lower portion with a connector that is insertable into the channel transverse to the longitudinal direction and the connector, once inserted into the channel, is retained from removal out of the channel in a direction. The connector is insertable into a first portion of the channel and a second portion of the connector rotatable into a second portion of the channel and then slidable away from the first portion such that the first and second portions of the connector are retained within the channel but are slidable in the longitudinal direction until the connector is fixedly secured to the beam. The frame is made in certain aspects from a flat plate.

A medical chair with height adjustable armrest comprises a lifting mechanism, a base coupled to a bottom side of the lifting mechanism, a sitting part coupled to an upper side of the lifting mechanism, and a backrest part coupled rotatably to the upper side of the lifting mechanism. An armrest comprises an armrest stop with the armrest rotatably coupled to the backrest part adjustable to an upper position and a bottom position, where, in the bottom position, the armrest stop bears on the first stop coupled to the backrest part, and in the upper position, the armrest stop does not bear on the first stop. A latch system movably attached to the backrest part comprises a latch with back surface and a second stop where the latch system is adjustable into a first position of the latch mechanism and into a second position of the latch system where in the first position of the latch system, the latch is located between the first stop and the armrest stop and in the second position of the latch system, the latch is not located between the first stop and the armrest stop, and where an upper position of the armrest is a position where the armrest stop bears on the second stop or any other position where the armrest is higher than in case when the armrest stop bears on the second stop.

A convertible seat including: a support frame; and a user support having a support surface on one side defining a rounded periphery, the user support being movable from a first configuration supported by the support frame with the rounded periphery presented upwardly, to a second configuration supported by the support frame such that a seat or seat base is presented upwardly, the seat or seat base being substantially flat or at least less rounded than the rounded periphery, with the support surface being stowed substantially below the seat or seat base in the second configuration.

The seat allows the attainment in a single unit both the healthy balance/core-strengthening of a fitness chair and a conventional chair.

A body support structure includes a frame and a membrane attached to the frame. The membrane includes elastomeric filaments. The membrane includes different regions with different stiffness. The membrane may form a part of a seat or a backrest.

An armrest includes a gear assembly with a crown gear directly coupled to the armrest that imparts rotational motion to the armrest, a planetary gear engaged with the crown gear, and a pinion gear coupled to the crown gear that imparts vertical motion of the entire gear assembly, and the armrest, along a rack.

A folding chair includes front and rear supports that fold and/or retract into central beams to reduce the space occupied by the chair in a folded configuration. A backrest is coupled to the central beams with a hub that allows an angle of the backrest relative to the central beams to be selected and for the backrest to be folded flat relative to the central beams. One or more actuators and pin actuators may control the relative movements of the backrest, front support, rear support, and central beams.

The present invention relates to a chair for supporting a person feeding a baby. The chair includes a seat. The chair includes an armrest operatively connected to the seat. The armrest is selectively rotatable about a vertical axis, and moveable forward/rearward, laterally inward/outward and vertically relative to the seat. The armrest is shaped to receive a baby thereon.
