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.
