Furniture manufacturer Hayworth worked with the designer Marie-Virginie Berbet to create what they call "a sleeping revolution." Called Calmspace (or (Calm)space to be more accurate), this brilliant piece of furniture is a regenerating power nap capsule. The user simply chooses a duration of time for their nap and the pod then uses a preset sound and light cycle to gently send him/her off to sleep and wake them up at the appointed time. The light and sound technology was provided by a company called Zyken, and are said to be scientifically catered to benefit a sleeping body.
These pods were designed to be used in office buildings to quickly recharge a tired employee, but we don't think these would be a terrible idea for the home either.
