  • Slip-resistant step stool and a method of manufacturing the same
    Patent number: 6886660
    Abstract: A slip resistant step stool includes a step surface with four legs extending downward. A slip resistant surface is bonded to the step surface. The slip resistant surface may be disposed in a pocket and have a ridge surrounding it. The slip resistant surface can be a thermoplastic elastomer. The stool can be manufactured by inserting the slip resistant surface in a mold adapted to form a step stool, then injecting molten resin into the mold, thereby bonding the resin to the slip resistant step stool.
