Choosing the right mattress size is crucial for a great night’s sleep. Whether you’re shopping for a standard UK mattress, a Euro King (also known as IKEA King), or a US size mattress like the California King, this guide breaks down all the popular mattress sizes, dimensions, and what they mean for your comfort and bedroom space.

Popular Mattress Sizes in the UK

Single (90 x 190cm): The classic choice for kids, teens, and single sleepers.

Small Double (120 x 190cm): Perfect for guest rooms or growing teenagers who need more space.

Double (137 x 190cm): The most common mattress size for couples in the UK.

King Size (150 x 200cm): Offers extra width and length for couples wanting more space.

Superking (180 x 200cm): Our widest standard UK mattress, providing maximum comfort.

Emperor (200 x 200cm): The largest standard UK mattress size - ultimate luxury and space.

Many sizes are also available in longer lengths (e.g., King Long 150 x 210cm) and extra-long versions, ideal for taller sleepers.

What Is a Euro King Mattress?

The Euro King mattress (160 x 200cm), often called an IKEA King size, is slightly wider than the UK King and offers a modern alternative for those seeking extra width without extending length. Popular in European homes, it’s an excellent choice for couples wanting a little extra room to stretch out.

Understanding US Mattress Sizes

• USA Queen (60" x 80") – Similar in length to a UK King but narrower.
• USA California Queen (60" x 84") – Extra long for taller sleepers.
• USA California King (72" x 84") – Longer and narrower than a standard King, popular in the US.
• USA American King (76" x 80") – Wider than a US Queen, similar in length.

Our range of US size mattresses brings American comfort to UK bedrooms, handmade with the same quality and customisation as all Robinsons Beds.

What About Odd or Custom Sizes?

If you have a bed frame or room with unusual dimensions, our odd size mattresses category offers bespoke options tailored to your exact measurements. From large emperors (214 x 214cm) to extra-long singles (90 x 220cm), we craft every mattress to order.

Why Choose Zip & Link Mattresses?

Many of our mattresses come in Zip & Link configurations. This means a large mattress can be split into two smaller mattresses joined by a zip, making it easier to move upstairs or through tight spaces, plus allowing couples to choose different firmness levels on each side.

Mattress Firmness Explained

• Medium Firmness: Balanced comfort and support.
• Firm: Extra support for those who prefer a sturdier feel.
• Extra Firm: Maximum support for spinal alignment.
