Bathing becomes dangerous when standing is unsteady, and a stool only helps if it cannot slip or sink. Six height settings from 14.2 to 19.09 inches step in one inch increments, and each locks with a spring loaded push button, so the legs cannot creep down under weight mid shower. Four non slip foot pads grip both textured and smooth tub floors, while large drainage holes stop water pooling on the seat, which is where slips happen when standing up. The frame is industrial grade aluminium alloy with five reinforced screws under the seat, rust proof and rated to 350 lbs yet light enough to lift in and out of a tub. A shower head holder frees both hands, a storage bag keeps soap and a towel within reach, and assembly needs no tools.
