Inside the Factory (2015)

Season 5: Episode 4

How a factory in Leeds produces 600 bouncy beds every day - from making steel into springs, to their placement in individual pockets and covering in natural fibres like hemp and wool designed to wick away sweat. How a short, twenty-minute sleep improves reaction times. How wool is shorn from sheep, and its inherent anti-bacterial and fire-retardant properties that make it well suited to mattresses. How the modern spring mattress evolved. How a famous Scandinavian-inspired home store is responsible for popularizing the duvet.
