5 Best European King Size Mattress UK – An Expert Buyer’s Guide

Last Updated on 16 Mar. 2020

I think everyone has been betrayed by a European sized bed frame before, I remember one of the flats I rented, the mattress would always slip down because there was a 10 cm gap at the bottom.

The reason?

It was a double mattress in an Ikea European double bed.


But I’m glad you’re here because it means you aren’t going to make the same mistakes. The problem is though a good EU size mattress is hard to find, so I’ve gathered my top 5 picks here, Just click the names to head over to where you can buy them online.

Top 5 Best European King size mattresses

1. Top Choice – Simba Hybrid Mattress

The Simba Hybrid Mattres

Firmness: Medium-firm

Price & Reviews

The Simba Hybrid mattress is a superb choice of mattress regardless of what size you need, it comes up again and again across this site.

It’s made up of 5 unique layers each one working to keep you cool through the night. The top layer is the soft outer cover that heat and air can pass through easily.

Next layer you’ve got the memory foam that works to support your back easing any back pain you might have.

Next is the all-important pocket spring layer, these give the mattress the traditional bounce of a mattress so you don’t sink too deep and stay comfortable. Made even better because there are 2500 of them! That’s really high and a great sign of a good quality mattress.

2. Best Memory Foam Choice – Silentnight Memory 7 Zone Mattress

 Silentnight Memory 7 Zone Mattress
  • Hypoallergenic
  • Comes in a box
  • Made in the UK
  • 5-year guarantee

Price & Reviews

This is a cool memory foam mattress, it’s split into seven sections each one with a different firmness so you get all the right support just where you need it.

Firmer support under your head and feet and slightly softer under your hips and shoulders so they can sink just that little bit more keeping your spine aligned.

This mattress is delivered in a box so you can get it into the correct room nice and easily.

I like this mattress, it’s comfortable, it’s fairly inexpensive, the only problem is it’s only 20 cm thick compared to 25 cm of the Simba above. This means if you’re a lot heavier then you might feel the bed frame underneath you.

But for most people, this mattress is perfect, comfortable, a 5-year guarantee, good for any sleep position. Nice one.

3. Best Pocket Spring Choice – Spring King Pocket Riviera 3000 Natural Mattress

 Spring King Pocket Riviera 3000 Natural Mattress

Firmness: Medium-Firm

  • Wool, cashmere and silk feelings
  • No roll together so great for couples
  • Good for back and side sleepers
  • 5-year warranty

Price & Reviews

A fine choice of pocket sprung mattress, it’s got an extremely high 3000 springs which means it’s ideal for couples because you can each move with minimal motion transfer between you.

It’s medium-firm which is the “porridge that’s just right” of mattresses, ideal for back and side sleepers although front sleepers will get on fine too, they’ll just need a thinner pillow.

The natural fillings are a great touch because it stops the mattress getting too hot compared to using any foam. Spring mattresses are also the classic feel of a mattress, the type that everyone is familiar with. Comfortable, supportive and you get a 5-year warranty on a mattress that’s made in the UK.

4. Best For Bad Back – Coolflex Backcare Firm Mattress

Coolflex Backcare Firm Mattress

Firmness: Firm

  • Orthopaedic support
  • Cooling air vents on the side
  • Delivered in a box
  • Needs flipped

Price & Reviews

Got a bad back but looking to get a good night’s sleep? This is a great choice. I’ve reviewed a lot of mattresses for bad backs but finding one that’s a European king-size is more difficult, which is why I love this one.

It’s a firm orthopaedic feel made with standard springs that are all connected on a grid, this makes it less ideal for couples as you’ll feel each other’s movement but if you’re dealing with back pain or you’re heavier then this is a fine choice.

This mattress does need to be flipped every 6 months to keep it fresh but this can be great to keep it feeling like a new mattress year after year. If you’ve got a slat bed however you’ll want to flip it more often.

This is a fine cheap mattress that will have you sleeping soundly and your back finally eased. The Simba at the top is also a great choice for back pain.

5. Best Hybrid Choice – Kayflex Pocket Plush 2000 Series Mattress

 Kayflex Pocket Plush 2000 Series Mattress

Firmness: Medium

  • Hypoallergenic
  • Great for couples
  • Ideal for side sleepers
  • 5-year warranty

Price & Reviews

The Simba is my top choice of Hybrid mattress but this is a cheaper alternative that still does a good job.

The pocket springs provide you plenty of bounce and comfort while the memory foam works to keep your back happy.

With the lower price, you don’t get as long a guarantee, just 1-year, but you do get a 5-year warranty so if anything goes wrong, or it starts to sag far too much you should be able to do something about it.

It’s been treated to be hypoallergenic to keep your bed fresh and free from dust mites which is a nice touch to finish off with.

European King Size Mattress Types

Memory Foam – Memory foam mattresses are great at providing back support as well as stopping you from rolling around so much through the night so you sleep deeper and wake up more rested.

A great choice for couples, side sleepers, back sleepers and back pain sufferers.

Pocket Spring – Pocket sprung mattresses have a more traditional feel, plenty of bounce but the pocket springs stop motion transfer so you don’t feel other people in the bed as well. Comfortable and generally cooler than memory foam.

A great choice for people who don’t like memory foam, cooling, and most sleeping positions depending on firmness.

Hybrid – A combo of both spring and foam come together to give you the best of both worlds, some traditional bounce with lots of back support and minimal motion transfer to keep you still through the night.

A great choice for – heavy people, back and side sleepers and couples.


Which is bigger, a UK king-size or an EU king size mattress?

An EU king size mattress is 160 x 200 cm long while a UK king size is 150 x 200 cm, which is why you get the gap at the bottom of the bed if your bed frame doesn’t match up with your mattress. A UK super king, on the other hand, is 180 x 200 cm so is the bigger size if that’s what you want.

How big is a Euro king mattress?

It’s 160 x 200 cm. Short and sweet eh?

Are all bed sizes different in Europe?

Yes, none of them quite match up which is why it’s important to know which size you’ve got, in the same way, a small single and small double won’t fit on a single or a double bed frame you want to know what size your bed frame is so you can get the correct mattress for it.

Where can I buy bed linen this size?

I like John Lewis bedding, it’s super comfortable, soft, high-quality and generally, you’ve got peace of mind that you’re sleeping on something substantial. And they’ve got a load that’s a European king-size! Check it all out here.

Again like the mattress, you need to make sure you’ve got the right size of bedding for your mattress otherwise it won’t fit properly and it’ll bunch and hang saggy off the sides quickly getting uncomfortable and irritable.


And that’s it! I hope this has helped you find a European king size mattress, no matter what mattress type you were looking for.

These are the best ones in my opinion but that doesn’t mean there aren’t other great mattresses out there, so if you know of a different mattress you’ve had your eye on don’t worry, just because it isn’t on this list doesn’t necessarily mean it isn’t a good mattress.

The Simba remains my top choice, it’s comfortable, great for all sleeping positions, works on all bed frames and will have you sleeping soundly night after night for a decade, what’s not to like?
