What size is a double mattress?

A double mattress size is 135cm wide and 190cm long. In imperial measurements, this is 4 feet 6 inches wide and 6 feet 3 inches long (4'6" x 6'3"). It's the most popular mattress size for average-sized bedrooms, since they provide enough room for two people, without overcrowding bedroom space.

How to choose a double mattress?

  1. Decide who the mattress is for. You should have 10cm (4 inches) of space between the end of the mattress and your feet. If you are taller than 180cm (5'11"), you will be more comfortable with a king size or superking mattress
  2. Select the right firmness level for you. Choose from softer, medium, medium-firm and firmer double mattresses
  3. Choose your mattress type. You can choose from a variety of options, including memory foam, pocket sprung mattresses, natural mattresses and much more!

Are double mattresses expensive?

Not necessarily! Take a look at our great range of double mattresses under £300. If you have a little more flexibility in your budget, you could choose a double mattress between £300-£400. If you want the very best quality, browse our double mattresses over £400.

It's worth considering that for every £50 extra you spend on your mattress, this equates to only 2p per night over 7 years. This could make a big difference to your sleep!

Is a memory foam or pocket sprung mattress better?

Both memory foam and pocket sprung mattresses are great choices. The majority of mattresses actually include both! Pocket sprung mattresses are best for optimal support and natural spinal alignment. Memory foam mattresses are best for pressure relief and provide personalised comfort for your unique shape.
