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 137cm wide. If you share your bed that’s just 68.5cm 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.
All other size mattresses are available upon request or visit our bespoke mattress and bespoke mattress topper page for further information. For information on IKEA sizing visit our IKEA Mattresses and Toppers size guide page.
