Height-adjustable support surface and system for encouraging human movement and promoting wellness

A sit-stand desk for use by a user, comprising:

• a frame;
• a panel having an upper work surface, said panel being vertically slidably attached to said frame and selectively vertically displaceable;
• at least one electrically-powered vertical-displacement drive mechanism mechanically connected between said frame and said panel, said drive mechanism being arranged to selectively vertically displace said panel with respect to said frame when said drive mechanism is activated;
• a control circuit connected to said drive mechanism for selectively activating said drive mechanism to vertically displace said panel according to prescribed oscillatory displacement instructions in response to receipt of a trigger signal;
• and
• a temperature sensor connected to said control circuit and configured to determine a body temperature of said user, wherein said control circuit is configured to generate said trigger signal based on changes in said body temperature.

• a panel having an upper work surface, said panel being vertically slidably attached to said frame;
• at least one electrically-powered vertical-displacement drive mechanism mechanically connected between said frame and said panel and configured to selectively vertically displace said panel with respect to said frame;
• a control circuit connected to said drive mechanism and configured to activate said drive mechanism to vertically displace said panel following a height-adjustment schedule;
• and
• a pressure mat comprising a pressure sensor connected to said control circuit and configured to determine a frequency of user movement between positions on the pressure mat,
• wherein said height-adjustment schedule is automatically adjusted by said control circuit in response to changes in said frequency.
