Sealy United Kingdom operates under licence from Sealy Incorporated in North Carolina, USA. The company's success in the UK started in 1974, following the acquisition by the Silentnight Group of local bedding and furniture company M Hackney & Co, in Aspatria, West Cumbria. Sealy quickly started to flourish and has since established itself among the top UK bed manufacturers and employs approximately 400 people, mainly from its own locality.
Sealy invests more time and money on product development than any other bed manufacturer, utilising state-of-the-art facilities at the world's largest and most advanced research and development centre and bed testing laboratory in Greensboro, North Carolina. This is in addition to the Silentnight Group's own research and development resource at Salterforth in Lancashire. An on-going commitment to research and development has resulted in Sealy winning various industry awards for quality, innovation and overall manufacturing excellence. This includes winning the prestigious 'Bed of the Year' award on two occasions. Sealy's range of divans and mattresses includes the Posturepedic - the world's best selling bed.
