A pair of leg supports are pivotally coupled at first ends thereof to a pivot point on the chair attachment assembly. Each leg support is independently moveable between a contracted position and an extended position. A leg holder is coupled to each leg support near a second end thereof. A resistance element is pivotally coupled between each leg support and the chair attachment assembly. Each resistance element is configured to provide resistance against both outward movement of the associated leg support from the contracted position to the extended position and inward movement of the associated leg support from the extended position to the contracted position.
