An assembly of a highchair having a smooth seat, and a thin, flat, compliant pad freely covering the seat surface. The pad is made from one piece of solid, rubbery material providing a high coefficeint of friction, and it has a matrix of apertures formed through it, each defined by a sharp peripheral edge at its juncture with the faces of the pad. The pad conforms to the seat in an anti-slip relationship, and it provides good mechanical interengagement with the diaper or garment of a baby seated upon it, despite the lightness of the baby\s body.

A chair assembly comprising, in combination: a chair, including a seat portion having a smooth upper surface; and a thin, flat, compliant pad dimensioned and configured to substantially cover said upper surface of said seat portion, said pad being freely disposed upon said seat portion surface with one face thereof lying in direct contact therewith, said pad being about 0.06 to 0.125 inch thick, and being devoid of covering layers and integrally formed, as a single piece, from a solid, rubbery material having a durometer value of about 30 to 50, a tensile strength of at least about 2000 pounds per square inch, and a coefficient of friction of at least about unity, as determined in combination with a smooth surface of wood, said pad having an array of apertures formed therethrough and arranged substantially entirely thereover, each of said apertures being defined by a sharp peripheral edge at the juncture thereof with the other face of said pad, and providing an opening of about 0.05 to 0.3 square inch, said apertures cumulatively defining an open area constituting about 20 to 30 percent of the total area of said pad, whereby said pad inherently exhibits high levels of conformability to, and slip resistance with, said seat portion surface, good mechanical interengagability with supple members pressed upon said other face thereof, and good strength and durability characteristics.
