Buying guidance

How to Choose a Mattress Topper

Start with the condition of the existing mattress, then choose the material, feel and thickness that match the change you want to make.

Does a mattress topper make a difference?

Yes, when the mattress underneath remains structurally sound. A topper can add cushioning and change the surface feel without replacing the complete mattress.

What type of topper should I choose?

Choose a memory foam mattress topper for a slower response that follows the body more closely, a standard foam mattress topper for a more immediate feel, or a high density foam mattress topper for firmer support. Some products use the label orthopedic mattress topper or orthopaedic mattress topper, but neither term is a regulated foam grade. Compare the verified material, firmness and thickness.

What thickness should I choose?

A 2.5cm memory foam topper makes a lighter adjustment, 5cm creates a more noticeable comfort layer and 7cm is the deepest memory foam option. All standard foam toppers are 5cm thick.

Before ordering: Measure the mattress, check its condition and compare the exact dimensions in each product card. Use the data-sheet link when you need technical information about a specific foam grade.

Ask the All Foam Team
Does a mattress topper make a difference?

A mattress topper can make a noticeable difference when the mattress underneath remains structurally sound. It can change the surface feel, add cushioning and provide a softer, firmer or more responsive comfort layer depending on the foam selected.

What are the disadvantages of a mattress topper?

A topper increases the total bed height and changes the feel of the mattress beneath it. A topper that is too deep, too soft or too firm may not suit every sleeper, and it cannot correct broken springs, deep sagging or structural mattress damage.

What type of mattress topper is best?

The right type depends on the feel required. A memory foam mattress topper responds more slowly and follows the body more closely, while a high density foam mattress topper gives firmer support. Some products use the label orthopedic mattress topper or orthopaedic mattress topper, but neither term is a regulated foam grade. Compare the stated material, firmness and thickness.

What memory foam topper thickness should I choose?

Choose 2.5cm for a lighter adjustment, 5cm for a more noticeable memory foam layer or 7cm for the deepest option in the All Foam memory foam range. Consider the condition and firmness of the mattress beneath it.

Can a mattress topper repair a sagging mattress?

No. A topper can adjust comfort on a mattress that remains structurally sound, but it cannot repair broken springs, a damaged support core or significant sagging.

What is the difference between a mattress topper and a mattress protector?

A mattress topper is designed mainly to change comfort and support. A mattress protector is normally thinner and is intended to protect the sleeping surface from spills, moisture and everyday wear.

What is the difference between memory foam and standard foam toppers?

Memory foam responds gradually to heat and pressure and follows the body’s contours. Standard polyurethane foam offers a more immediate feel, while different grades provide softer, firmer or more resilient support.

How do I choose the correct mattress topper size?

Measure the sleeping surface and compare it with the exact dimensions shown on the product card. All Foam toppers are available in Single, Double, King Size and Super King dimensions.

Are All Foam mattress toppers made in the UK?

Yes. The memory foam and foam mattress toppers on this page are made in the UK.

How long does a mattress topper take to deliver?

Orders normally take one working day to process. Once dispatched, they are sent using a 24-hour courier service, so delivery is usually made on the next working day after dispatch.
