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 | Metric (cm) |
Nearest imperial equivalent (feet/inches) |
||
|---|---|---|---|---|
|
Images below are for guidance only |
Width | Length | Width | Length |
Single
|
90 | 190 | 3' | 6'3" |
| Standard 3ft size, perfect for growing children, but it may be worth considering a longer bed if the sleeper is tall. | ||||
Double
|
135 | 190 | 4'6" | 6'3" |
|
First of the 3 most popular standard sizes suitable for couples. You
have a cosy 67.5cm each. Consider a longer bed if you are tall. |
||||
King
|
150 | 200 | 5' | 6'6" |
| Most popular bed for two in the UK, you have 75cm each, and the sleeping area is 10cm longer than a standard double. | ||||
|
Super King 
|
180 | 200 | 6' | 6'6" |
| The biggest and best of the standard sizes, it gives two sleepers 90cm each, and is same length as a king size. | ||||
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 special UK sizes | Metric (cm) |
Nearest imperial equivalent (feet/inches) |
||
|---|---|---|---|---|
|
Images below are for guidance only |
Width | Length | Width | Length |
|
Small Double
|
120 | 190 | 4' | 6'3" |
|
Plenty of space for 1 to stretch out, but extremely cosy for 2. Great for smaller bedrooms where a standard double won't quite fit. |
||||
|
Euro King
|
160 | 200 | 5'3" | 6'6" |
|
For larger vintage or continental beds this size is often referred to
as a 'continental double'. The more room to sleep in the better. Great if a super king won’t quite go. |
||||
|
Emperor
|
200 | 200 | 6'6" | 6'6" |
| The largest of all of our special sizes, an Emperor mattress gives those with large bedrooms the maximum amount of sleeping space, so if you share you both have room to spread out and relax. | ||||
What about Mattresses for 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* | Metric (cm) |
Nearest imperial equivalent (feet/inches) |
||
|---|---|---|---|---|
| *Adjustable beds are often longer than the nearest equivalent static model. Make sure you measure properly before you order. | ||||
|
Images below are for guidance only |
Width | Length | Width | Length |
|
Small Single 
|
75 | 200 | 2'6" | 6'6" |
| 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. | ||||
|
Long Single 
|
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. | ||||
|
Long Small Double 
|
120 | 200 | 4' | 6'6" |
| Suits smaller non-standard continental frames, and smaller adjustable beds in small double width (120cm). These generally have just a single handset or mechanism to raise and lower the mattress. Often they are longer than static bed bases. Make sure you measure properly. | ||||
|
Long Double
|
135 | 200 | 4'6" | 6'6" |
| Adjustable beds in standard double width (135cm) generally have just a single handset or mechanism to raise and lower the mattress. Often they are longer than static bed bases. Make sure you measure properly. | ||||
King
|
N/a | N/a | N/a | N/a |
| See small single (75cm width). You will need to order two of these for your adjustable base if using each mechanism independently. Some adjustables also have a synchro function which 'locks' dual units so they rise and fall in unison. If this a permanent requirement of your adjustable bed base, then you may be able to use a 1 piece king size mattress instead. | ||||

Easy to remove - easy to wash
All TEMPUR® Sensation 21 mattresses are made with removable covers washable at temperatures of up to 60°C. Just zip them off for a machine wash to keep your mattress clean and fresh.
In the main, refurbished TEMPUR® products have either been previously sold directly by TEMPUR® or via one of our stockists and subsequently returned. Often this is after a home trial where the consumer has changed their mind about the feel of their mattress and chosen another model better suited to their needs. Another reason may be that an item has incurred minor cosmetic damage during handling. Occasionally the item may be an ex-display model which has been on show in one of our own stores or at an authorised stockist.
Each product is evaluated under a strict set of guidelines by a member of the TEMPUR® team to ensure it is safe to use. Covers will have been removed and washed at temperatures of up to 60°C to refresh them before the item is made available for sale.
All mattresses purchased from the TEMPUR® Online Outlet are repackaged before they are dispatched. Each one is double bagged to keep it clean whilst in transit.
For pillows, where possible, we will recycle the original packaging, provided it is clean and intact. Occasionally boxes used may show signs of cosmetic damage, but this will not impact on the future performance of the product contained within.
Yes. This service is free. If you decide TEMPUR® is not for you, we have a 30 night money back returns policy for refurbished mattresses and topper 7s, and 14 nights for pillows. This is subject to the item you are returning, being received back at our distribution centre in the same condition as when it was dispatched. Once it has been successfully checked and re-inspected, we will be in touch regarding your refund. To find out how our returns process works, go to our Returns page.
Yes. All of our refurbished products are covered by the TEMPUR® Quality Guarantee, just the same as our new products. That's 10 years for a mattress or topper 7, and 3 years for a pillow. To find out more visit our Quality guarantee page.
Covers may vary from the one shown on our website. We will supply the item you have purchased or the nearest equivalent which may be a higher specification at no extra cost to you. The decision to send an upgraded item is dependent on what is available at the time you place your order. Each listing shows the minimum specification you can expect to receive. Our refurbishment programme operates on a first come first served basis. We do not offer a reservation service for items listed in Outlet.
We release refurbished products for sale only after final inspection has been completed. Availability is very much dependant on what has come back to us at any specific point in time. These items sell quickly. All we can advise is just keep checking and don’t delay ordering if the right item for you shows as in stock.
