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"). This size of mattress is often referred to as a 4ft 6 mattress. 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?

When shopping for a double bed mattress, there are a few important factors to consider to make sure you make the right purchase:

  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!

What's the best double mattress for my sleeping position?

The best double mattress for you depends on your sleeping position. You can choose a mattress based on whether you sleep on your side, back or front.

Most of us are side-sleepers. If you sleep on your side, we recommend a double mattress with a thick comfort layer. This helps to cushion your hips and shoulders. Take a look at our hybrid mattresses - they include memory foam, gel or latex for soothing comfort and pressure relief.

If you sleep on your back, you'll need good support to keep your spine in healthy alignment. Back-sleepers should consider a medium-firm or firm double mattress with pocket sprung support.

Do you sleep on your front? We recommend a double mattress with plenty of comfort and pocket sprung back support. You can choose a double hybrid mattress in the firmness rating of your choice.

Are double mattresses expensive?

Not necessarily! Take a look at our great range of cheap 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.

Our double mattress sale is unmissable if you're working with a tighter budget. Featuring mattresses from some of the leading brands, you can take advantage of generous discounts, putting better quality mattresses in your price range.

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.
