Bed size guide

When you’re looking for a new bed frame, divan bed or mattress, it’s important to choose the one that’s right for you and the best fit (literally), for your bedroom. Our guide is here to help you decide the best size for your room, that leaves you sleeping easy.

What sizes are available?

From smallest to largest, the four most common sizes of bed or mattress are single, double, kingsize and super kingsize. There are some additional size choices for mattresses and bed frames, including small double, shorty and toddler.

Mattress size vs frame size

The size of a mattress and bed frame will always match; meaning a double mattress will fit on a double bed frame and so on. There’s no matching required with a divan bed, as it is a mattress and bed frame all-in-one.

Choosing a mattress or divan bed?

The size is generally standardised, meaning wherever you buy from in the UK – it should be the same size. The size of bed frames can vary depending on the design, so the sizes below are only for mattresses and divan beds. And remember, a mattress should always fit on a bed frame of the same size.

Bed sizesShop by bed size

SINGLE BED - W 90CM/L 190CM

As expected, designed simply for just one person.

DOUBLE BED - W 135CM/L 190CM

Same length as a single, but wider. Ideal for couples or individuals that like to stretch.

KINGSIZE BED - W 150CM/L 200CM

Wider & longer than a double. Great if you're tall, or don't like fighting for the covers.

SUPER KING - W 180CM/L 200CM

Even wider than a kingsize, but the same length.

SMALL DOUBLE - W 120CM/L 190CM

A narrower style of double. Perfect space-saver.

More bed buying considerations

To me, to you

There are two main considerations when choosing the right bed size. Firstly, will it fit in the room of your choice? You might like the room and comfort that a larger bed offers, but how much space will that leave for any wardrobes or other bedroom furniture? The second consideration is whether you can get it to its new home. Will the bed or mattress fit through your front door and up any stairs?

Don't get cold feet

If you’re a touch on the tall side, you might want a bed that doesn’t leave your feet dangling, or leaving you having to sleep diagonally. Kingsize beds offer 10cm more length than a double, which might be the difference between waking up to cold feet or not.

Out with the old

We offer a mattress recycling service, where you can pay to have your old one taken away. When you add mattress to your trolley, you'll be given the option to have your old one removed when the new one is delivered. This service doesn't apply to headboards, bed frames or divan beds, so make sure to remove these before your order arrives.
