ABSTRACT:
Disclosed is an improved kneeling apparatus for cement masons which allows substantially unencumbered movement across large expanses of unset cement surfaces while simultaneously providing ample support to eliminate marring and pocking of finished surfaces. The apparatus includes a pair of spaced-apart platforms, each containing peripherally disposed upstanding side walls and an extending handle. Each platform surface is adapted to interchangeably accept the knees or the feet of the user. A mason, while working wet unfinished cement, can shift and otherwise distribute his weight such that one or the other of the surfaces can be lifted and moved by means of the handle, without upsetting or divoting the unset surface.
