Abstract
A chair mat especially designed for use in both a sitting and standing position can have a substantially rigid base including a fold line separating a first portion of the base from a second portion. A resilient cushion can positioned on only the second portion lower surface of the base. The second portion can be movable about the fold line relative to the first portion between a first position where the cushion is downwardly facing and a second position where the cushion is upwardly facing. When the second portion is in the first position, the substantially rigid base can present a substantially continuously smooth upper surface providing for easy movement of any casters or rollers supporting a desk chair spider. When the second portion is in the second position, the cushion can provide a compressible yet resilient portion that facilitates a comfortable standing working position for prolonged periods of time.
