Our Single 4G Pocket Sprung Memory Foam Mattress offers a superb level of support by distributing your body weight evenly. Our fourth generation foam sits on a 1500 pocket spring base. The open spring design of the pocket sprung base allows air to circulate effectively, complementing the aerated structure of our 4G memory foam. The 1500 individual springs react independently to any changes in weight allowing the mattress to respond to your natural movement & is an advantage if there is a weight or size difference between you & your partner. 4G foam features all the pressure-relieving benefits of memory foam with advanced heat dispersion technology. The innovative structure enhances airflow, creating a more breathable & odourless foam so you can wake up feeling refreshed. The unique design ensures heat & moisture is removed naturally as you sleep regardless if you move position or keep still during the night. Our 4th Generation Pocket Sprung Memory Foam Mattress has a zoned sleeping surface for optimum support. The mattress is finished with a quilted Adaptive Purotex cover. Purotex is an active probiotic which is woven into the fabric to absorb moisture & eliminate dust mites creating an anti-bacterial sleeping surface for a healthier sleep.
