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.
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.
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.
As expected, designed simply for just one person.
Same length as a single, but wider. Ideal for couples or individuals that like to stretch.
Wider & longer than a double. Great if you're tall, or don't like fighting for the covers.
Even wider than a kingsize, but the same length.
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?
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.
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.
