More information about memory foam mattress toppers

How a memory foam mattress topper works

Memory foam responds to body heat and pressure, allowing the topper to follow the body's contours and spread weight across a wider area. This can alter the surface feel of an existing mattress and provide a more pressure-responsive comfort layer.

Choosing between 2.5cm, 5cm and 7cm thickness

A 2.5cm topper makes a lighter adjustment to the mattress feel. A 5cm topper provides a more noticeable memory foam layer, while a 7cm topper creates the deepest and most enveloping option in the range. The best thickness depends on the existing mattress, sleeper preference and required level of cushioning.

When a mattress topper is suitable

A topper is intended to change the comfort feel of a mattress that remains structurally sound. It is not a permanent repair for a mattress that is damaged, heavily worn or sagging. Where the complete sleeping surface needs replacing, compare the foam mattress range.

Memory foam topper care

Use a suitable protector, keep the topper dry and ventilated, and follow the care information supplied with the product. Avoid folding or compressing the topper for long periods once it is in use.

More information about foam mattress toppers

What is a foam mattress topper?

A foam mattress topper is made from polyurethane foam and is designed to sit on top of an existing mattress to adjust the comfort feel and add an extra layer of support.

Choosing the right foam topper grade

The medium-density option provides a softer feel, while the high-density option provides firmer support. Reflex Superior Medium offers a medium luxurious feel, and Reflex Superior Firm provides a firm luxurious feel with fast foam recovery.

How should a foam topper be positioned?

The topper should be laid flat on top of the existing mattress and covered with a suitable protector or fitted sheet. The best setup will depend on the mattress beneath it and the comfort feel required.

Fire-retardant foam and technical information

The foam toppers are made from fire-retardant polyurethane foam. Each product title includes a link to the correct technical data sheet for the foam grade used.

Helpful answers

Mattress Topper FAQs

These answers cover common questions about memory foam and foam mattress toppers, including sizing, delivery, comfort and use. Product-specific details should always be checked on the individual mattress topper products.

Ask the All Foam Team
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.

Is VAT charged on mattress topper orders?

All Foam is not currently VAT registered, so VAT is not charged on orders. Delivery options are shown clearly at checkout.

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, deep sagging or a damaged support core.

What memory foam topper thickness should I choose?

Choose 2.5cm for a lighter comfort adjustment, 5cm for a more noticeable memory foam layer, or 7cm for the deepest option in the range. Consider the existing mattress and the level of cushioning required.

What is the difference between memory foam and foam toppers?

Memory foam responds gradually to heat and pressure and follows the body’s contours. The polyurethane foam toppers offer straightforward comfort and support, with different foam grades available for softer, firmer and more resilient feels.

How do I choose the correct mattress topper size?

Measure the existing mattress and compare it with the exact dimensions shown in the size selector. Choose the topper size that matches the sleeping surface rather than relying only on the size name.

Are All Foam mattress toppers UK made?

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

Where can I find technical information about each topper foam?

Use the underlined Data sheet link beside each product title to open the technical data sheet for the foam grade used in that topper.
