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 genuinely 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.

If the dip is shallow and the core underneath is still sound, yes, and you want the 7.5cm for that. It bridges the dip and gives you a level surface again. If the springs have gone or you can feel the base through the mattress, a topper will just follow the shape of the problem and you'll be disappointed. At that point you need a new mattress, and we'd rather tell you that than sell you a topper.

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.

Every topper has anti-slip elasticated corner straps. UK and EU bed sizes are not the same, so check the size chart above before ordering, and measure your mattress if you're between sizes.

Latex allergies react to proteins in raw sap, and those proteins are washed out during manufacturing, so reactions to a finished latex topper are rare. Our cores are OEKO-TEX tested and sit inside a cotton cover, so your skin never touches the latex directly. If you have a diagnosed latex allergy, check with your doctor rather than taking our word for it.

The cover unzips and machine washes at 30 degrees. Never soak or wash the latex core itself. Keep it out of direct sunlight, UV breaks latex down over time. Give it a day to air when it arrives, natural latex has a faint milky smell that fades.
