Automatic bed making machine - Poboo.com

I remember someone once said that all inventions are ways to make humans lazier. I didn't believe it before, but after seeing the invention below, I believe it. At this year's Geneva Invention Expo, an Italian engineer invented an automatic bed-making machine. It has two滑rails on both sides of a regular bed. The clamps on the rails can fix your sheet, then you just need to pull this clamp and the bed is made. Moreover, the rail will automatically contract inward to hide the sheet inside the bed. For me, this is indeed a pretty good invention, but I guess my mom won't buy it for me.
