Light, easy to setup and has a great non-slip surface. When folded it forms a flat package easily stored. This is a VERY stable step, unlike some of the plastic models available.
TIP: Carry in a bag if storing under the bed, as the top of the step is like sandpaper - very non-slip which is great, but can rub on other items.
We now travel with the stop on the floor of the caravan on a non-slip mat.
