But a new option has arrived in the form of Cozy Room, a personal isolation chamber that contains everything you could wish for from a man (or woman) cave.

The Japanese manufacturers of Cozy Room describe it as a "relaxation room for man and woman." Unfortunately, any thoughts of sharing some alone time together with your significant other are shattered by the fact that Cozy Room is only designed to hold one person at a time. The whole thing measures 205 x 120 cm (81 x 47 in), but that shrinks considerably when the chair is pushed in to encase the incumbent on all sides.

Cozy Room comprises a single, high-backed chair which slides into a cubicle, the back of the chair becoming the fourth wall of the square unit. Inside is a desktop for a laptop or keyboard, room to hang a TV or monitor, an LED light, a display rack for action figures, and enough drawers and shelves to store all of your favorite personal belongings.
