Wheels For Your Knees
If you spend your days moving around on the floor, then you know what a toll it takes on your knees. The problem isn't so much that you are on your knees all day, but that you have to get up and down to move around or crawl on all fours. I have found 3 possible solutions that aim to solve the problems of moving around on the floor, and they range in price from $55 - $150.
