Just read a study out of Switzerland yesterday saying you need to take a couple naps during the week. It's good for your heart! Basically (no brainer but...) it helps you catch up on sleep your missing during the night.
Well, how about napping while at work? Seems like a win win!
Here is an effective way to do it with a chair that folds out flat!
Only catch is, they are a bit pricey. Just over $250....
