Gel Foam Mattress Topper - 5cm Cool Comfort

Deeper Cooling Comfort — 5cm Gel Foam Mattress Topper

For hot sleepers who want more than a light comfort layer, this 5cm gel-infused foam topper gives a fuller, more cushioned feel than our 3cm option while keeping the same cooling benefit — ideal if your mattress genuinely needs a comfort upgrade and you tend to overheat at night.

CoolCell: deeper gel-infused cooling
The extra depth means more of our CoolCell gel-infused foam between you and your mattress, giving noticeably more pressure relief and cushioning. The gel infusion keeps working to draw heat away from your body throughout the night, so the extra comfort doesn't come with the trade-off of sleeping hot.

Features

• 5cm gel-infused foam — deeper cooling comfort and pressure relief
• 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 — secure fit, no slipping
• 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

• Delivers a genuine comfort upgrade for mattresses that have gone flat or firm
• Keeps working to draw heat away from your body all night long
• Gives fuller pressure relief than a 3cm topper, without sacrificing breathability
• Stays securely anchored to your mattress, however much you move
• A smart alternative to replacing a mattress that's simply lost its comfort
