Just what I was looking for - safe height and step for ease of mobility/movement. Very secure with 4 rubber pins on the bottom. You get 4 steps that lock together. Another 4 would build it up to the ideal height as the leaflet recommends you have the steps at same height as the inner base of the bath. So I may buy more when I can. Excellent product. You get 4 steps that are very sturdy plastic - on the top surface is a layer of raised circles so you get the secure footing. Just be sure to dry top and the floor for the next use. Great value too.
