Abstract
A sheet material sling is supported on a horseshoe-shaped device mounted on three casters which forms a vehicle to support a knee of a user. Two such supports are used, unconnected to each other by users who must kneel in their work and must scoot along a support surface. Provisions are made for the supports to be interconnected by a flexible connector or by a rigid table like sheet.
