2-Tier Handy Steps 5 "Useful" Geraldine 24 July 2020 Bought as I've just put shelves in a cupboard and don't have a chair handy to stand on to reach the top shelves. These fold up to about 1 and 1/2 inches so they can live in the front of the cupboard. But I've used them to stand on to gloss the top of the door frames, could just about see to do so. I'm 5'7"s if that helps. Also easily replaced light bulbs using these. I couldn't see any instructions regarding closure nor was I able to find a button to press or pull. If you hold them with the steps towards you by the handle, reach down the back to wiggle the back bar they close.
