  • Review for Relyon Memory Original Mattress

    Superb product and service

    Bought a mattress from a local bed shop,at a much dearer price had it a month before giving it to a charity. Cannot believe the comfort and quality of the Relyon mattress,the speed it was delivered and the service I received from the lady I spoke to.

  • Review for Sleepeezee Cool Comfort 1400 Mattress

    Love this mattress.

    High quality mattress, really comfortable. I would say it feels more firm than medium, but it is very comfortable. I am really pleased with the mattress and the quick delivery. The delivery man was very helpful . Definitely recommend this product and company.

  • Review for Shire eco SOUND Mattress

    Lovely good quality mattress, firm but moulds to the body

    Lovely mattress, best I've ever had. Slightly firm at first but in the night your body moulds in to it. Can't fault anything except its a heavy mattress.

More on Super King Mattresses

Super King size mattresses are slightly growing in popularity today and are the largest standard size in the UK. If you share a bed with a partner, you should go for a Superking mattress as it will offer you both a royal sleeping surface. The more space you have to yourself in the bed, the better quality sleep you are likely to get.

 

When choosing a new mattress, bear in mind that mattress sizes in the UK remain the same whichever manufacturer makes the mattress. This is sometimes not the case for divans and besteads but always the case for mattresses. The industry standard for a superking size mattress is 180cm x 200cm, which is 6’. European and North American sizes for Superking mattresses can differ so be aware of this if you have imported your bed.

 

While mattress sizes are standardised in the UK bed industry, the depth of a superking size mattress will depend on the structure and the fillings within the mattress. In most cases manufacturers use combinations of different fillings to offer different support and comfort levels on the various sleeping parts of the mattress.

 

Airsprung, Relyon, Relyon or Silentsleep - whichever brand you choose, nearly all their mattresses will be available in a 6ft and you can choose from a variety of comfort levels, firmnesses, fillings, finishes and types. Including pocket sprung, memory foam and latex.
