Memory Foam

Memory foam has long been a customer favourite for its body-moulding surface, which absorbs weight and allows you to blissfully sink into sleep.

Silentnight memory foam is responsive and also relieves pressure on the places where you need it most, such as the hips and shoulders.

Hot sleepers can sometimes struggle with memory foam because of its cocooning nature, but our Signature Memory Foam Collection comes with breathable borders to stimulate airflow for a cooler sleep.
