Mattress Topper

The 2.5cm is a comfort adjustment. It takes the edge off a bed that's slightly too firm and gives you a cooler surface, but it won't change how your mattress supports you. The 7.5cm really changes the feel of the bed. If your mattress has a dip, or it's been too firm since the day you bought it, that's the one you want.

Only a shallow one. If the dip is slight and the mattress core underneath is still sound, a 3 inch Supportive topper can even out the surface. If you can see a clear dip, or feel the base through the mattress, a topper will follow the dip and it is time to replace the mattress. Our 10-point mattress integrity audit helps you tell the difference.

They behave differently. Memory foam softens with your body heat and moulds around you, which is exactly why it traps warmth and why turning over feels like effort. Latex pushes back instantly and its open pinhole structure moves air through the sheet, so it sleeps cooler and you move freely. Latex also outlasts foam by a wide margin, a decade plus against three to five years.

Most people with a sore lower back are on a mattress that's either too soft to hold their hips level or too firm to let their shoulders in. A medium-firm latex topper is the safest starting point because it supports without going rigid. If the pain is persistent or waking you regularly, see a GP or physio rather than trying to buy your way out of it. Our 30-night trial exists so you can test the mattress theory without risk.

No, and it's the main reason people switch. Every core is pinhole moulded, so air moves through it instead of sitting trapped under you. There's no heat-reactive layer to hold warmth in.

Our toppers come in UK sizes: Single 90 x 190 cm, Double 135 x 190 cm, King 150 x 200 cm and Super-King 180 x 200 cm. The standard version has an anti-slip base to stop it sliding. Measure your mattress before ordering, and if it is a European size, email us first.

Please don't buy a latex topper if you or anyone sharing the bed has a latex allergy. Organic latex is still natural rubber latex, and NHS guidance lists latex mattresses and pillows among the products people with a latex allergy should avoid. Choose a latex-free topper instead.

The cover unzips and is machine-washable; follow the care label. Never soak or wash the latex core. Keep it out of direct sunlight, as UV breaks latex down over time, and rotate it head to foot every few months. When it arrives, give it a day to air: natural latex can have a faint smell that fades.

Delivery is free to the UK mainland, sent tracked with Parcelforce (Highlands, Northern Ireland and Shetland £9.99). Every topper comes with a 30-night trial. Terms apply, see our returns policy and how trying at home works.

The latex core is GOLS-certified organic Dunlop latex and the cover is GOTS-certified organic cotton. The finished topper isn't certified as a product, because our cover maker and UK finishing partner are not yet certified sites. Our own certification is in progress. Here is exactly what is certified.
