Kingsize Memory Foam Mattresses (under 15cm Thick)

Designed to provide supportive everyday comfort, this 12.5cm deep full-foam mattress features next-generation open-cell Reflex Foam with a medium-firm feel. With no springs inside, the mattress provides consistent support across the sleeping surface while offering a comfortable combination of cushioning and responsive bounce-back. The Reflex Foam structure is made up of thousands of tiny air cells that compress and respond as you lie on the mattress. This allows the foam to gently contour to the body while providing supportive resistance and returning to its original shape when not in use. Finished with a soft, breathable fabric across both the sleeping surface and border, the mattress encourages airflow to help manage excess heat and maintain a fresh and comfortable sleeping environment throughout the night. For convenient delivery and easier handling around the home, the mattress is compressed, vacuum-packed, rolled and boxed. Once unpacked, allow approximately 24–48 hours for the mattress to fully expand and return to its intended size and shape.
