Abstract: A mat includes a mat body defining an upper surface dimensioned for a user to stand on the upper surface. The upper surface is non-planar and includes at least one terrain feature defining the non-planarity. The terrain feature has a size that is on the order of magnitude of the size of the user's foot. Presenting this surface to the user may help remind him or her to move his or her feet to thereby adopt multiple poses, thereby preventing the user from maintaining any single pose for a fatigue-inducing duration.

Abstract: A desktop includes a first portion, a second portion, and a linkage assembly attached to the first and second portions. The first desktop portion has a first, substantially planar, upper surface, and an edge. The second desktop portion has a second, substantially planar, upper surface, a proximal edge, and a distal edge. The linkage assembly is configured such that the second desktop portion is movable between a first configuration and a second configuration. At the first configuration, the second desktop portion is substantially coplanar with the first desktop portion, and the proximal edge of the second desktop portion is adjacent the edge of the first desktop portion. At the second configuration, the proximal edge of the second desktop portion is beneath the edge of the first desktop portion, and the second desktop portion is not coplanar with the first desktop portion and is not parallel to the first desktop portion.

Abstract: An apparatus includes a platform and an actuator. The platform includes a first platform region with a first surface, and a second platform region with a second surface. The actuator is operatively coupled with the first platform region and with the second platform region, and moves the apparatus between a first and a second state. At the first state, the first surface defines a first orientation, and the second surface defines a second orientation, where the first and second orientations are substantially symmetric and the first and second surfaces are substantially at the same height as one another. At the second state, the first surface defines a third orientation, and the second surface defines the second orientation, where the third orientation is not symmetric with the second orientation. The availability of more than one platform configuration encourages a user standing on the platform to assume varied standing postures.
