Find the perfect double mattress for your bed

A double mattress is one of the most popular mattress size options, offering a good balance of comfort, space and practicality. Also known as a 4ft6 mattress, it is a great choice for a double bed in a main bedroom, guest room or smaller sleeping space where you want room to relax without moving up to a larger bed.

Our double mattress collection includes a range of double mattresses designed for different sleepers, comfort preferences and budgets. Whether you are replacing an old bed mattress or choosing a double bed mattress for a new bed frame, the right mattress can help improve your sleep experience and make your bedroom feel more comfortable.

Comfort and support for a good night’s sleep

Choosing the right mattress can make a real difference to how well you sleep. Memory foam mattresses can offer a cushioned, contouring feel, while pocket spring mattresses are designed to give responsive support. If you prefer a firmer feel, an orthopaedic mattress may also be worth considering.

The best option depends on the sleeper, their sleep style and the level of comfort and support they prefer. Some people like a soft, luxurious feel, while others need something more supportive. By thinking about firmness, mattress type and how the bed will be used, you can find the perfect match for a more restful night’s sleep.

Choosing the right firmness

Firmness is an important part of finding the perfect double mattress. A softer mattress can feel more cushioned, while a medium mattress may offer a balanced feel for many sleepers. A firm mattress can provide a more supportive surface, which may suit those who prefer a sturdier sleep setup.

The right firmness often comes down to personal preference, but it can also depend on your sleeping position, body support needs and bed frame. If you are unsure, visiting our stores can help you compare different comfort levels and choose a mattress that feels right for you.

Why choose a 4ft6 double mattress?

A standard double mattress is designed to fit a 4ft6 double bed, giving one sleeper plenty of room or offering a practical sleeping space for a couple. It is wider than a single mattress but more compact than a king size, making it an ideal choice for many bedrooms.

Before you shop, it is worth checking the width of your bed frame and the manufacturer’s size guidance to make sure your new mattress is the right fit. This helps ensure optimal comfort and keeps your double bed feeling supportive night after night.
