Artist Jamie O'Shea's Vertical Bed combines two of my favorite things: sleeping. Standing can go f*** itself, because I hate it. I like lying down.
The Vertical Bed won't save you from poking and prodding, but with sunglasses on, noise-canceling headphones, a neck-pillow for comfort, and an umbrella to keep you dry, that's a pretty good start. The Vertical Bed will keep you upright thanks to hooks attached to the shoes that will lock into subway grates, and braces and concealed harnesses that keep your legs and back supported. It all conveniently folds down into a briefcase.
You know, I tried to sleep standing up once, but when I started to doze I fell over. To my credit though, I was pretty drunk -- on life! Just kidding, it was the shine.
