  • Review for Relyon Memory Pocket Serenity 1500 Mattress

    Like it a lot

    Thank you for your help today, and thank you for arranging delivery so quickly. After looking around I went for the memory + pocket springs because I'm a bit heavier than most. Vert good quality and happy that I bought this one. Now I'm going to look for a bed too. The only complaint I would have is that I couldn't speak to your customer team in the evening, but thank you for answering my email. Regards, Simmo.

  • Review for Sleepsnug Refresh 1000 Mattress

    Very good

    We wanted something which would protect us from dust mites and was healthy. We decided on the budget and then did our research. We thought that memory foam + pocket springs would be better than our last mattress which was just memory foam. So far no complaints. It's very good quality and we like it. Thank you, please say thank you to your customer service lady for her help today.

  • Review for Relyon Luxury Cashmere Pillowtop 2200 Mattress

    Comfortable

    I have absolutely no idea about anything related to mattresses, so when I found this site and they had so much information, I found it helpful. I decided to go with the pillow top because I like something medium and a little soft (I'm not a big man). Can't complain, sleep very well on this! Thanks,.

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.
