Abstract: An adjustable seating solution that enables users to adjust several seating characteristics is disclosed. In a relatively low sitting position, the disclosed device provides some support if the user leans back, but predominately supports the user's weight and requires the user to engage core muscles to maintain good posture. The disclosed apparatus enables the user to adjust the seat upward to a leaning position. A platform extends forward under the user's feet to ensure that when the user leans against the seat, the apparatus remains stable. The apparatus enables the seat portion to be tilted, such that varying contours can be selected to engage the user's body in a desired way. At low heights, the user can tilt the seat portion forward to require the user to further engage core muscles while seated. At higher heights, the user can customize the contour of the seat that engages the user's body.

Abstract: The invention discloses a pedestal apparatus for an article of furniture. The pedestal apparatus has an elongate post formation defining a first end and a second end and having a longitudinal axis. The post formation immovably supports a fixed foot arrangement and also movably supports a variable foot arrangement. The variable foot arrangement is selectively movable along and around the longitudinal axis for varying a longitudinal and angular proximity between the variable foot arrangement and the fixed foot arrangement. Biasing means are provided for controlling movement of the variable foot arrangement whereby, in use, the biasing means causes both the fixed foot arrangement and the variable foot arrangement to abut an underlying surface and thereby provide a substantial stabilization of the pedestal apparatus.

Abstract translation: 本发明公开了一种家具用基座装置。 基座装置具有限定第一端和第二端并且具有纵向轴线的细长柱形结构。 柱形结构不可移动地支撑固定脚布置并且还可移动地支撑可变脚布置。 可变脚布置可选择性地沿着纵向轴线移动，以改变可变脚布置和固定脚布置之间的纵向和角度接近。 提供了用于控制可变脚部装置的移动的偏压装置，由此在使用中，偏置装置使得固定脚布置和可变脚布置都抵靠下面的表面，从而提供基座装置的实质稳定。
