Of course, many different circumstances 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 you want? No matter the answer to those questions, we’ve got every mattress size available, ensuring something perfect for you.

Small Single

Width 75cm X Length 190cm

A small single mattress is ideal for younger kids with narrow beds. 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, making it ideal for guests.

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

A small single ensures they can enjoy their first bed with a comfortable mattress that effortlessly fits 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 an excellent option for kids as it’s unlikely they will grow out of it throughout their teens, meaning it’s a perfect long-term option. 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. 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, we have the small double, which serves many purposes again. If you’re a restless sleeper or enjoy more space, this is a better option than a single. The added distance comes in width, evident by the measurements of 120cm by 190cm, and provides extra space 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. The small double can do the job if you don’t have space or seek a little more.


Width 135cm X Length 190cm

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

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

King Size

Width 150cm X Length 200cm

The king-size is the one for all 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 mattress.

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

The downside is that not everyone has room for a king-size, preventing many people from buying it. Yet, if you do, it’s worth it. With so much space 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 more significant and provides you with much room. A 6FT mattress measures 180cm by 200cm and is the biggest available in the UK.

You and your partner can roll over and starfish all night, although it presents the identical obvious drawback as the king-size.

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

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.

Moreover, each mattress comes in a different style, with many great options 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 you won’t go wrong with our extensive range in all sizes.
