Double mattresses are one of the most common mattress sizes available to buy. Measuring 4ft6" by 6ft3" (or 135 x 190cm), they’re the standard mattress size for the majority of double beds in the UK and Europe.
Unlike smaller double mattresses, standard double mattresses are 15cm wider, giving you and your partner that little bit of extra room you need for a seamless night’s sleep or a cosy snuggle on those slow weekend mornings.
As with all mattress types, there are a variety of double mattress options available for you to choose from, each made from different materials to accommodate various sleeping styles and comfort preferences.
For example, our two most popular double mattress types include memory foam and pocket-sprung technology, which allows us to accommodate customers seeking either a modern or traditional sleeping experience.
Built using a multitude of individually cushioned springs, our pocket-sprung double mattresses provide consistent comfort for users throughout the entire night. Their bouncier nature is perfect for those seeking a springier feel, and their intentional ventilation properties make them ideal for regulating body heat while you sleep.
Sitting slightly more on the softer side, memory foam double mattresses are designed for those who prefer a bed they can sink into. Their foamy material seamlessly transforms to the shape of your body's natural contours, allowing for a more tailored sleeping experience and making memory foam models great all-around mattresses.
Besides traditional pocket springs and memory foam, if you’re looking for a specific type of double mattress, other popular options in our range include hybrid mattresses, latex mattresses, orthopaedic mattresses, and hypoallergenic organic mattresses, all of which come with either pocket springs or foam as their mattress filling.
How firm you want your new double mattress to be is entirely up to you and should be based on personal preference. However, if you’re buying a double mattress for the first time, then we recommend thinking about the following:
Your previous mattress firmness – if you’ve always slept on a particular type of mattress firmness and you like that level of support, then you should definitely look for a double mattress that matches this firmness level.
Your sleeping position – mattress firmness and sleeping positions are directly linked. Back and front sleepers typically want firmer mattresses for better support, while side sleepers should look for softer mattresses that let them sink into the bed for a natural spinal alignment.
Your body type – the heavier your body type the firmer you’ll want your new double mattress to be, that way, you can give your body the support it needs for a better night’s sleep.
The price of buying a double mattress will depend entirely on what type of mattress you go for, and how much you want to spend.
Budget mattresses can cost as little as £130-£150, while more expensive pocket sprung and memory foam mattress options may cost around £300 for a basic model, all the way up to over £1,000 for a top-of-the-range option.
But, at the end of the day, a good double mattress is an investment, and a well-maintained mattress can last for years to come. So, even if you’re on a tight budget, it may be worth spending a little more so you can enjoy great sleep well into the future.
Our guide to how much a good mattress should cost can help you manage your budget more easily. Plus, we offer flexible finance options on all of our double mattresses!
