Double Mattresses

Q: 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 .

Q: 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 .

Q: 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.

Q: 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.

Frequently Asked by Our Customers

What size is a standard double mattress?

As the name suggests, a double mattress (also known as a full-size mattress) is ideal for two people, and typically measures 135cm wide by 190cm long or, 4'6" x 6'3".

That said, if you need a little more room (or a lot!), we also offer king-size, European king-size, and super king-size mattresses. Find your ideal size mattress or bed in our handy guide.

Short on space? No matter. We also stock smaller mattress sizes, including our single and small double ranges, which are perfect compact rooms, solo sleepers, and children and teenagers.

What is the best double mattress for me?

Well that depends! Your sleeping position can greatly affect the type of double mattress you need, so it’s best to consider how you sleep and where you need support the most.

For example, a softer, more pliant double mattress may be better suited to a side sleeper, whereas a front sleeper may feel more supported by something firm. And for all you back sleepers, we’d recommend something between the two.

Need help deciding? Use our simple mattress firmness guide to gain a better understanding of the firmness ratings best suited to side sleepers, back sleepers, and front sleepers.

Which mattress is the best for couples?

For couples, we’d recommend a double mattress, or, if you’re short on space a small double.

If you each require a different level of firmness, it’s typically best to opt for a medium-rated mattress as they’re the most universal and accommodate a wide range of sleeping positions, meaning you’ll both be supported.

How many pocket springs are in a double mattress?

Typically, double mattresses boast anywhere between 1,000 and 2,000 pocket springs.

That said, a higher spring count doesn’t necessarily mean better quality, and the materials used play an equally important role in the comfort of a mattress.

Our patented Octaspring® and Octasmart® mattresses feature our original foam springs, with a memory foam top layer and supportive Ecocell® foam base for ultimate comfort each night.

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

We’d advise against it. A double bed is slightly bigger than a small double so for premium comfort and support, we’d recommend putting only a double mattress on a double bed frame.

By doing so, you’ll ensure an even distribution of support, improving your chances of a restful night’s sleep.
