What is the best single mattress?

The best single mattress is one that provides the best comfort and support for you - with enough space to get a good night's sleep!

Here's how to choose:

Decide who it's for - is it for you, your child or a guest?
Pick the right firmness - choose from softer, medium, medium-firm or firmer
Consider allergies - select a hypoallergenic mattress
Choose the best type - including memory foam, pocket sprung, or natural fillings
Combine with a new bed - browse single beds for the perfect package!

What size is a single mattress?

A standard UK single mattress size measures 90cm wide and 190cm long (90cm x 190cm). In imperial dimensions, that's 3 feet wide and 6 feet, 3 inches long (3' x 6'3").

Single mattresses are a good size for one person. They're great for a child's bedroom, guest room or smaller bedroom where space is limited. Since they fit neatly into smaller spaces, they can be used in other rooms too, such as an office or box room.

Are you looking for a different size? We have a range of other single sizes too, including:

European single - great for taller individuals
Small single - perfect for your child's first bed
Small single short - best for very small bedrooms

What are the different types of single mattress?

If you want to buy a single mattress, you'll find that there are many different types to choose from. The best type for you depends on a range of factors including your sleeping position and comfort requirements.

Here are some of the best types:

Memory foam - contours to your shape for pressure relief
Pocket sprung - individual springs provide great back support
Gel - cool and fresh, helpful if you overheat
Hybrid - combination of springs and foam layers for the best of both worlds!

Which is the cheapest single mattress?

You can buy a single mattress for less than you might think! We offer a range of budget-friendly cheap mattress options, ideal especially if you need one for the spare room, or for your growing family.

At Mattress Online, our prices start from just £100. With huge discounts from big-name brands, you can shop the best deals on single mattresses - and get Free Next Day Delivery too!
