  • What size is a king size mattress?

    King size mattresses measure 5' x 6'6" (150 cm x 200 cm).

  • How big is a king size mattress compared to a standard double mattress?

    A double mattress measures 4'6" x 6'3"(135cm x 190cm) while a king size mattress measures 5'0" x 6'6" (150cm x 200cm). This makes a king size mattress 15cm wider and 10cm longer than a standard double mattress.

  • What is the average life of a king size mattress?

    A decent quality king size mattress, if cared for properly, can last for many years. The National Bed Federation recommend replacing your mattress every 7-8 years.

  • Is a king size like a Queen size mattress?

    The term Queen size refers to an American mattress measuring 4’ 9” x 6’ 6” (152cm x 203cm). A king size mattress is the closest UK equivalent. If you are looking for a queen size mattress, then a king size mattress is the closest match you can find here in the UK.
