It might seem strange to refer to the Squatty Potty as "bathroom tech," but those who have used it know that even an innocuous plastic stool can be revolutionary technology. Don't have one? Well, this Prime Day 2021 you're in luck: It's even cheaper than its usual low price.

So, what exactly is a Squatty Potty? It's a small plastic step that sits around the base of your toilet. Putting your feet up on it will allow you to achieve more of a squatting position than you'd typically get, which experts say can be helpful. That might not sound dramatic—and I was incredibly skeptical at first myself—but it actually makes a significant difference.

First of all, it just immediately feels more comfortable. You don't need to strain or push at all: Gravity and your positioning will do most of the work. It cuts down on straining, makes for an easier clean-up afterwards, can help overcome constipation and can significantly speed up the time you spend, well, squatting. In fact, the experience is so much better that many reviewers (as well as myself and several of my colleagues) say that it makes using other toilets seem awkward, poorly designed and absolutely low-tech by comparison.

While the Squatty Potty is never expensive, if you shop now, you can snag one for less than $20 while it's still on Prime Day sale. Trust me: It'll be the best $20 you'll ever spend.
