Purchased this handy step for my wife, but it serves many other purposes around the home thanks to its 15.5ins height.
It seems to be fairly rugged, although at first I did wonder how safe it was as the lugs on the sides, were not locking them into a rectangular shape, but inverting them in by about an inch. On closer inspection, there are stops for the lugs on the underside of the step which prevent the stool folding once your weight is on it. I weigh over 100 kg and have used the stool several times now with no problem at all, but would not advise it for the elderly or youngsters, due to its height alone. (unless they have something close by to hold onto).
It appears to come in three different colours, we wanted a white one (it has a black & white top) which we received by sending a short email to the seller via Amazon. It folds up easily and neatly, and the protective rubbers fitted to the leg base's are a nice finishing touch.
Depending on your own height it brings you up to a level where you can reach ceilings, curtain rails, tops of tall robes etc, etc. Definitely a handy addition to the home.
