Very hard sell. Most people love <i>not</i> sleeping in a box, and love their double or queen size beds.<p>And how would ventilation work? The box is powered, with its own climate control? What about safety such as waking suddenly in the dark and cracking your head on your sound proof box, or needing a quick exit in emergency?<p>Nobody wants a very large ugly thing in their small bedroom, used only sometimes. Can it be folded away? Unlikely.<p>Sorry, but a sound proof box for sleeping in is the worst idea I&#x27;ve heard in a long time!! Funny though. A better idea is noise cancelling headphones which can be worn in bed - soft, no hard edges or wires so can sleep on your side without issue.
