How It's Made — Innerspring Mattresses, Stand-Up Paddle Boards, Vacuum Cleaners
Steel wire is formed into coils and combined with layers of cotton, polyester and upholstered fabric to build innerspring mattresses. Fibreglass and resin are laminated around moulds to form stand-up paddle boards, while electric motors, fans, filters, housings and controls are assembled and tested in both bagged and bagless vacuum cleaners.
