IKEA Mattress Sizes Guide

There is nothing more frustrating than buying a new mattress and finding it doesn’t fit your bed perfectly. I wish it was a simple as there being some universal sizes for small, double, king, etc across the world, but it’s not that simple.

I’ve put this IKEA mattress sizes guide together to show you how IKEA mattresses and beds are different to Standard UK mattress sizes.

It’s not huge differences, but you need to be aware of the differences as you’ll end up with a mattress not fitting your bed or vice versa if you’re not careful.

Euro Bed Sizes

If you think these measurements are familiar it’s because they are standard Euro mattress sizes. Being Swedish, IKEA use Euro bed sizes across their range of products.

If you’re looking for other beds and mattresses that have the same dimensions then you need to search for Euro Single, Euro Double, Euro King, and so on.

UK Standard Sizes

The UK have their own standard sizes that differ from the Euro sizes used by IKEA. For clarity, here are the UK sizes:

Why It’s Important to Have the Right Mattress and Bed Sizes

It’s really important to have the right size mattress and bed or you risk damaging them. If you have a Euro size mattress for example and put it on a UK standard size bed, the mattress is going to overhang by a few inches.

This will cause the mattress to bend in an unnatural way along the edges. A coil spring mattress will probably bend out of shape and there is a chance it will roll out off the edge. It’s also going to damage memory foam and possibly even tear it.
