Disclosed herein is a dynamic pendula stool possessing a foot, a leg secured to the foot, and a seat secured to the top end of the leg. The leg has a telescopic column that includes a lower part secured to a spherical foot with a diameter of 20-cm or less and an upper part with a free end having an articulation. The articulation has three degrees of freedom and is secured to the underside of the seat so that when a user rests against the seat, the leg forms an angle between 30 and 90 degrees with respect to the horizontal, thereby allowing an isometric contraction of the muscle groups of the lower limbs and of the abdominal girdle in the seated position. The stool is further provided with one or more sensors configured to send data signals to a remote electronic device.

A dry and wet land gear holder for supporting equipment for a hunter or wildlife observation enthusiasts. The holder includes an upper and lower support members that are telescopically extensible and retractable relative one another. The lower support member has a plurality of outwardly extending legs supporting the holder in a vertical orientation. A plurality of pegs for supporting the user's gear. The holder may be configured with an accessory that is received within a top end of the holder. The accessory may include a camera mount, a sighting rest, and a horizontal support platform, which may be configured as a work surface or a seat. The legs and bottom end of the lower support member may have ground penetrating tips to secure the holder in an upright position relative a ground surface.

A pelvic tilt detecting chair is provided to a user to sit and configured to detect a pelvic angle of the pelvis of the user in sitting position. The pelvic tilt detecting chair comprises a base, a supporting component, a carrying component and a detector. The base has a horizontal surface. The supporting component comprises a first end connected to the base and a second end. The carrying component is moveably configured and comprises an installing surface coupled to the second end and a chair surface configured to contact the pelvis of the user. The chair surface and the horizontal surface form a tilt angle when the user sits on the carrying component. The detector stores a tilt angle threshold value and is configured to the carrying component to detect the tilt angle. The detector generates a warning signal when the tilt angle is not matched up with the tilt angle threshold value.

The invention relates to a platform for a variably adaptable piece of furniture and to a piece of furniture with such a platform. The platform has a base, a column and a mounting bracket for mounting interchangeable accessory modules. The universal mounting bracket has a mechanical mounting interface for mounting and dismounting interchangeable accessory modules. The platform has electrical functionality. The platform also has an identification interface for identifying an accessory module mounted on the platform and a control unit. The control unit is adapted to receive identification information about an accessory module mounted on the platform from the identification interface and to control an adaptation of the electrical functionality of the platform depending on the received identification information.

A removable swim-up dock bar is described. The dock bar is removably attachable to a submerged foundation of an existing dock and may have adjustable seats or adjustable legs to ensure proper height and stability.

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.

Storage of chairs when not in use, for instance in halls used by various groups, is a common problem which has been addressed by providing chairs that are stackable upon one another. Usually, this requires the chair to be composed of sloping legs and a sloping backrest, such that the seat of a lower chair can fit between the legs of an upper chair, and the backrest of the upper chair can rest on the backrest of the lower chair. It is desirable to be able to stack chairs with as small a vertical displacement as possible, usually limited by the depth of the seat, which is typically substantially horizontal. For instance, the base of an upper seat may sit (when stacked) on the upper portion of a lower seat. However, these chairs are usually mass produced and so designed to fit the average shape, which is not accommodating for a lot of people. The present invention provides a chair where seat 13 height, back 3 angle, seat 13 tilt and seat 13 roll are adjustable.
