A good night's rest really isn't what cars are designed for. Or is it? In fact, a handful of cars have been designed specifically with sleeping in mind. A few cars actually have bed space built in. Let's be clear here: we're talking about cars with proper, purpose-built bedding, or at least seats that fold completely flat to make up a bed.
The decidedly odd 2011 Tubik concept from CitroÃ«n feels a bit like a luxury flat on wheels. The middle and rear sets of seats are designed to fold completely flat, creating a set of aeroplane-style seats that you can sleep in. Citroën has even made a stab at creating a post-sleep breakfast theme, too, by making the Tubik look like a giant toaster.
