Liquid Stands Ergonomic Piano Foot Rest Under Desk - Height Adjustable Elevated Metal Foot Stool with Handle

I'd been using a 7ish" tall cardboard box under my desk as a footrest. It had worked great for a few months. Then it started drooping, and I knew I couldn't do without the support. Enter the Liquid Stands footrest.Assembly was easy, fast and I was foot resting in about 5 minutes. The lowest setting is just perfectly the same height as the box, and my feet are back in heaven. The anti-skid coating on the top is great for the bottoms of the feet, and the cats are now finding it great for their nails. The feet on the bottom are hard plastic, so it slips a bit on the floors. I put on a set of felt bumpers so it won't scratch, and actually reduces the slip just a bit. But, it's under the desk, the desk is against the wall, so it's not slipping far.

Love this step stool! Easy to build (instructions could be a tad bit more clear ….. but I eventually got it) very simple adjusting mechanism. My 4 year old is able to do it by herself. Great product, sturdy, and will be bringing this with us for each of her piano lessons.
