Knee replacement protector.
My wife recently had a knee replacement and is still recovering with considerable pain. We have indoor cats and one in particular loves to jump in our laps, via our legs, curl up and nap. Our tom jumped up and landed squarely on her knee which sent her straight up in the air, voicing a few choice words, threatening several of his nine lives. The incident certainly made him exit for part unknown for several hours. It was not intentional, we know, but it made us consider a precaution to prevent it from happening again.
We have a fireplace in our living room. In front of the fireplace is a three section folding ember screen. The light bulb in my wife's head lit. The two folding sides fit down on both sides of her legs allowing the center section to cover and protect her upper legs from falling objects and pouncing paws. It also serves as a lap table. It works for us and I thought we would share. Hopefully it will help others as well.
