You'll want to have a few of these risers on hand to help you safely navigate your exterior stairs in the rain, sleet, or snow, and so much more to make mobility a little easier. The Support Plus medical step stool is just 3 1/2" high, so the low stool is an excellent solution for anyone who has difficulty lifting their legs or feet to take a full step up. Use it indoors as a bath or bed step stool, garage stool, or even as a low-profile step up exercise platform. With a non-slip top featuring drainage holes that reduce standing water in rain or sleet, it's ideal for use outdoors on a porch or deck, and works great on-the-go as a car step stool or RV step stool. Sturdy single step stool is crafted from tough plastic with wide rubber feet for stability, and makes a useful gift for seniors and disabled or injured loved ones.
