Gel Foam Mattress Topper - 3cm Cool Comfort

Stay Cool, Sleep Comfortably — 3cm Gel Foam Mattress Topper

If you run warm at night, standard memory foam can make things worse — trapping heat right where your body needs it to escape. This 3cm gel-infused foam topper is designed to solve that specific problem: a light comfort layer that adds cushioning without the "too warm" feeling some foam toppers bring.

CoolCell: gel-infused foam that manages heat
Our CoolCell foam is infused with cooling gel that helps draw heat away from your body as you sleep, rather than holding onto it the way standard memory foam can. The result is a topper that still contours gently to your body, but without the warmth build-up — a good entry point if you want extra comfort without a thick topper changing the overall feel of your bed.

Features

• 3cm gel-infused foam — cooling comfort with gentle contouring
• CertiPUR-EU certified foam — tested for content, emissions and durability
• OEKO-TEX certified zip-off cover — removable, soft-touch fabric that's fully machine washable
• Elasticated corner straps — secures the topper firmly to your mattress
• Anti-slip base — keeps the topper in place under the cover
• BS7177 compliant — meets UK fire safety regulations for domestic bedding
• Rolled and vacuum-packed — compact delivery, ready to unroll and expand

Why it works

• Helps prevent the overheating that standard memory foam can cause
• Adds a light, comfortable layer without drastically changing your mattress feel
• Ideal for hot sleepers who still want gentle pressure relief
• Stays anchored securely to your mattress throughout the night
• A cost-effective way to freshen up an older or firmer mattress

Available in every UK mattress size, from single to super king.
