How to choose the best single memory foam mattresses

The luxurious memory foam material feels exquisite to lie on and will give a comfortable night's rest every time. Our single memory foam mattresses are easy to take care of and will add an air of refinement to any bedroom.

Measuring 3 feet, they also offer a compact sleeping solution for any bedroom. This can come in handy when designing a child's room or a smaller bedroom.

Our memory foam mattresses come in a choice of firmness ratings so you can pick one which is tailored to your personal preference. Go softer if you like, or choose a firmer one if you require extra support. Whichever one of our single memory foam mattresses you choose, we are sure you will love it.

What size is a single memory foam mattress?

Single foam mattresses are generally the same dimensions as other single mattresses and measure 90 x 190cm or 3’0 x 6’4. They’re commonly referred to as 3’ singles. Bear in mind that certain brands such as Ikea, and European mattress sizes are slightly larger, so you will need to ensure you buy the right single memory foam mattress to fit your bed frame.

What is the best single memory foam mattress?

This is all down to personal choice. The majority of memory foam mattresses are medium to firm, so they’ll provide plenty of support regardless of the manufacturer. However, better quality mattresses also incorporate extras such as cool fabric covers to keep you cooler, or allergy-free latex layers for greater support.

Check out our full range of memory foam mattresses for more information.

How thick is a single memory foam mattress?

Single memory foam mattresses range in thickness, but the average is around 23-25cm, which will provide you with plenty of support, even if you’re a side sleeper.

Can you get mattress toppers for a single memory foam mattress?

Yes. Any standard single mattress topper should fit your single foam mattress perfectly, giving you an additional layer of cushioning for a softer feel.
