UK MATTRESS AND BED SIZE GUIDE FROM TEMPUR®

THE TEMPUR® UK MATTRESS AND BED SIZE GUIDE

SIZE MATTERS!

Sleep is essential to everyone’s health and well-being, but how many of us realise that the space where we choose to sleep has not necessarily changed in size since we were babies in the cradle? The width of the average cot is approximately 75cm. A standard double bed, one of the most popular sizes in the UK, measures 135cm wide. If you share your bed that’s just 67.5cm each! The fact is, the more space you have to sleep in, the better your night’s rest will be.

Here's a basic guide to mattress/bed sizes to help you make the most of your bedroom space. We recommend you should always work in metric for the most accurate measurements, but if you prefer feet and inches, then we have listed the nearest equivalent size to help you.

1 piece mattress in standard UK sizes


Alongside the 4 main standard sizes it could be you own a bed base which none of the above quite fit. Below are a couple less common alternative sizes that we can provide for those customers that need them:

1 piece mattress in standard UK sizes


What about Adjustable Beds?

If you own or are thinking of buying an adjustable bed base, then it is quite possible the mattress or mattresses you need will not be standard UK sizes.

As always it pays to measure up first.

Sizes to fit single or dual adjustable beds*

*Adjustable beds are often longer than the nearest equivalent static model. Make sure you measure properly before you order.


All mattress measurements are approximate. Please allow for a tolerance of +/- 2cm when you order.

TEMPUR® mattress weight capacity is approximately 150kg per side (23 stone)


AND WHAT IF MY BED IS NOT ONE OF THESE AND I NEED A SPECIAL SIZE, OR CUSTOM MADE MATTRESS?

In such cases we always recommend you visit one of our specialist retailers for best advice. They will be more than happy to guide you through the ordering process, and ensure you get exactly what you need.

For narrow single frame beds or order 2 for a standard king size or king adjustable bed base. If both mattresses are the same height (e.g. 21cm, 25cm or 30cm), you can each select different models and sleep on them side by side.

90 200 3' 6'6"
10cm longer than a standard single. If you share a standard super king bed and you and your partner prefer different feels, you can select 2 different models and use them side by side provided both mattresses are the same height (e.g. 21cm. 25cm or 30cm). For super king adjustable bed bases with dual mechanisms you will need to order 2 mattresses also the same height.
