Choosing the right mattress size is just as important as choosing the right comfort and support. One of the most common issues we see at The Sleep Shop Athlone is customers who have bought a European or IKEA bed frame and then struggle to find a mattress that fits correctly.

In this guide, we’ll explain what European mattress sizes are, how they differ from UK and Irish sizes, why IKEA beds often need special sizing, and how to choose the correct European mattress for long-term comfort and support.

What Is a European Sized Mattress?

A European sized mattress is designed to match bed frames manufactured to continental European dimensions. These sizes are commonly used across mainland Europe and by retailers such as IKEA.

While European mattresses may look similar to UK or Irish sizes, they are often slightly longer or wider, meaning a standard mattress may not fit properly.

Even a few centimetres difference can cause:

• Gaps around the mattress

• Overhang at the foot or sides

• Reduced comfort and support

• Faster wear on the mattress edges

European vs UK & Irish Mattress Sizes: What’s the Difference?

This is where many people get caught out.

UK and Irish mattresses are made to standard domestic dimensions, while European mattresses follow a different sizing system. Although they are close, they are not interchangeable in many bed frames.

That’s why customers often come to us saying:

“My mattress almost fits… but not quite.”

If your bed frame was bought in Europe or from IKEA, a true European sized mattress is usually the correct solution.

Do IKEA Beds Need a Special Mattress?

In many cases, yes.

Most IKEA bed frames are designed to European sizing. Using a standard UK or Irish mattress can lead to:

• Visible gaps at the head or sides

• An uncomfortable sleeping surface

• Bedding not sitting properly

• Increased movement and noise

At The Sleep Shop Athlone, we regularly help customers who are replacing an incorrectly sized mattress on an IKEA or European bed frame. Choosing the right size from the start makes a huge difference to comfort and durability.

What Happens If You Use the Wrong Mattress Size?

Using the wrong mattress size doesn’t just affect how your bed looks — it affects how you sleep.

Common problems include:

• Poor spinal alignment due to uneven support

• Mattress shifting within the frame

• Faster breakdown of mattress edges

• Reduced lifespan of the mattress

A correctly fitted European mattress provides full edge-to-edge support, ensuring your bed performs as it should.
