Description

The 3000 Boxtop Firm 5ft King Size Mattress features 3 000 individual pocket springs that respond independently to your body weight, delivering precise support while reducing motion transfer.

Engineered to promote correct spinal alignment, it’s ideal for those who favour a firm sleeping surface without forfeiting comfort.

Beneath the surface lies a layer of innovative UltraGel memory foam, designed to cradle pressure points while still providing resilient support.

Gel-infused particles effectively disperse excess heat, ensuring the mattress remains refreshingly cool throughout the night.

A breathable CoolTouch cover further enhances comfort by wicking away moisture and improving airflow, guaranteeing a fresh feel from evening until morning.

Transform your bedroom—where reliable support, excellent temperature regulation and targeted pressure relief combine to deliver a truly revitalising night’s sleep.
