I used to work in a library so became acquainted for how well these rolling stools work to reach items on high shelves. Also known as a kick-stool, it rolls to where you want it and locks down when you step on it. Perfect.
I needed a decent stool for my home so looked for a kick-stool I could buy personally. I was delighted to see that Wayfair sells them at a decent price and in a range of colours.
