Frequently Asked by Our Customers

What size is a double mattress?

The standard double mattress size is 135cm wide by 190cm long or, 4'6" x 6'3". A double mattress (sometimes called a full size mattress) is ideal for two people but, if you're after something larger, you'll be pleased to know we offer king-size, European king-size, and super king-size mattresses.

We also have smaller mattress sizes, including our single and small double ranges, which are especially handy if you’re short on space. If you can’t decide on a size, take a look at our guide to find out what size mattress and bed are right for you.

What is the best double mattress for me?

The kind of double mattress that would suit you depends entirely on your needs and sleeping position. For example, side sleepers might sleep better on a soft mattress, while front sleepers may prefer something firmer. For back sleepers, we recommend somewhere in the middle.

Our mattress firmness guide will outline the best mattress fillings and firmness ratings for side sleepers, back sleepers, and front sleepers.

Which mattress is the best for couples?

For two people, we would recommend a mattress size no smaller than a double or, if needs be, a small double. If you both prefer two different mattress firmness ratings, a medium-rated mattress is generally the most universal, as they can suit a wide range of sleeping positions.

In this collection, you’ll find an extensive range of double bed mattresses to suit every sleeper. So, whether you're looking for a memory foam model, something pocket sprung, or a hybrid mattress that combines the best of both worlds, we've got you covered.

For more information on finding the right mattress firmness, depth, and fillings for you, take a look at our mattress buying guides for side sleepers, front sleepers, and back sleepers.

How many pocket springs are in a double mattress?

A double mattress can have anywhere from 1,000 to 2,000 pocket springs. However, a higher spring count doesn't always mean better quality, and the materials used can often determine the comfort of the mattress. Our patented Octaspring and Octasmart mattresses feature our original foam springs, with a memory foam top layer and Ecocell base for ultimate comfort each night.

Can you put a double mattress on a small double bed?

Because a double bed is slightly larger than a small double, we always recommend you place your double mattress on a double bed frame for the best support.
