An office-type chair includes a base, a height-adjustable pedestal extending upward from the base, a seat assembly including a rear seat part and a front seat part, and a linkage system connecting the pedestal to the seat assembly. The linkage system is adapted to pivot the seat assembly between a lowered position to serve as a task chair and an elevated position to serve as an elevated sitting support. A backrest arrangement may extend from the seat assembly. In the lowered position, the front and rear seat parts are both generally horizontally oriented. In the elevated position, the rear seat part may have a slight forward tilt and be positioned higher than in the lowered position, and the front seat part may extend at a downward angle relative to the rear seat part.

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 seating assembly for athletes includes seats having a back and seat portion, a base, an adjustable element, a user interface device, and a controller. The back portion includes a back heating member that provides heat to a user's torso. The seat portion includes a lower limb heating member that provides heat to the user's lower limbs. The base supports each seat. The adjustable element is coupled to the base and one of the seats and adjusts height of the seat. The user interface device receives an input regarding a desired temperature of the back heating member and the lower limb heating member. The controller receives the input and adjusts an operation of the back heating member and the lower limb heating member to achieve the desired temperature. The user interface device receives a second input to adjust the a height of the seat relative to the floor surface.
