Abstract: A novel apparatus for at least carrying and supporting the lower back of a supine oriented user engaged in plumbing related activities, at least includes: a substrate member; a padding layer coupled to the substrate member and adapted to cushion the support of the user; and at least three caster wheel members coupled to the side of the substrate member opposite the side of the padding layer. The effective height of the apparatus is adapted to substantially match the height of vanity or kitchen cabinets.
