Stability is one of the main features to look for in an adult step stool. It must be strong enough to support the weight of the individual but easy enough to move to other locations if needed.
If an adult needs extra support when getting into bed, a step stool with a handle or sidebar is advisable. Step stools need nonslip bottoms and a wide base. The stool should have wide enough platforms for large feet. Height is an important factor, and some stools are made with adjustable height control. There should be covering on the step platforms to avoid slippage.
