Of course, there are many different circumstances that will impact your choice.

Do you need room for two? Do you toss and turn throughout the night? And, is there space in the room for the mattress that you want? No matter the answer to those questions, we’ve got every mattress size available, ensuring there’s something perfect for you.

Small Single

Width 75cm X Length 190cm

A small single mattress is ideal for younger kids who have a narrow bed frame. As well as that, if you’re looking for something small and easy to fit into a spare room, this will do the job too. It can also be moved around easily, which makes it ideal for guests.

The width of the mattress measures at 75cm which should be a natural fit for all toddlers who are moving up from a cot.

A small single ensure they can enjoy their first bed with a comfortable mattress that will effortlessly fit into any kids’ room. And, given the small size, there will still be room for all toys!


Width 90cm X Length 190cm

The single mattress is suited for a range of people. Firstly, it’s a great option for kids as it’s unlikely they will grow out of it throughout their teens, meaning that it’s a perfect long-term option. Obviously, that also brings financial benefits as kids can grow fast, but the single mattress should still provide them with enough comfort over the years, and it measures 90cm by 190cm.

Furthermore, it’s ideal for those who sleep independently, providing you with enough space to sleep comfortably without taking up much space in the room. Given that, they’re also popular as guest beds for the spare room, which may not be as big as the regular bedrooms.

Small Double

Width 120cm X Length 190cm

Next up, we have the small double, and once again, it serves many purposes. If you’re a restless sleeper or enjoy more space, this is a better option than a single. The added space comes in width, evident by the measurements of 120cm by 190cm, and provides extra space that is needed for those of you who toss and turn.

Although, it can also be used for couples, primarily if you sleep closer together. Another reason for its popularity among couples is that it doesn’t take up much room. If you don’t have space or seek a little bit more, the small double can do the job.


Width 135cm X Length 190cm

Traditionally, this is the number one bed for couples. Measuring 135cm by 190cm, it will provide you with sufficient room for both of you to sleep peacefully without getting on each other’s nerves in the night!

Additionally, the double bed fits into standard bedrooms with ease. It’s also a great choice for the guest room, where a friend could enjoy the luxury of a double bed to themselves or couples could sleep in comfort. Either way, you can’t go wrong.

King Size

Width 150cm X Length 200cm

The king-size is the one for all of you who want plenty of room. Even sleeping next to your partner, you should be able to roll over without disturbing them in this 150cm by 200cm beast of a mattress.

From a logical perspective, this is ideal for the taller women and especially men out there, who look to stretch out without their feet hanging out the bed!

Obviously, the downside is that not everyone will have room for a king-size, which prevents many people from buying it. Yet, if you do, it’s worth it. With so much room and comfort guaranteed, you’ll enjoy a king-size mattress.

Super King Size

Width 180cm X Length 200cm

If you thought a king-size was good, this is even better. As the name suggests, the super king-size is even bigger, and it provides you with so much room. A 6FT mattress measures 180cm by 200cm and is the biggest available in the UK.

Both you and your partner will be able to roll over and starfish all night, although it presents the same obvious drawback as the king-size.

You may struggle to fit one of these into your room, but if you can, we’re sure you won’t regret it!

If that wasn’t enough, you could also check out our European mattresses in IKEA sizes that may appeal. Finally, you can build a custom mattress, with every detail from the length to the mattress’s width exactly how you want it, which we can then deliver.

That covers the fantastic, extensive range of mattress sizes available with Bedstar, and as you can see, we’ve got something for everyone. Whether you’re looking for a first bed for your toddler or want to relax in a super king-size, the perfect mattress is only a click away.

What’s more, each mattress comes in a different style, with many great options to choose from, all designed to give you the most comfortable night’s sleep possible.

So, what are you waiting for? We know that picking the right mattress is essential to a good night’s sleep, and with our extensive range, coming in all sizes, you won’t go wrong.
