This medium-support mattress is pocket-sprung to help you enjoy a gloriously comfy and restful sleep. Separate chambers for every spring ensure they respond independently to your body's unique contours. This design also reduces motion transfer, so you and your partner are less likely to disturb each other with small movements as you rest. Natural wool fibres combine cushioned support with excellent breathability, while our ActiPro anti-allergy cover ensures your sleeping environment stays clean and healthy by eliminating allergens. An antibacterial finish keeps things fresh, while four vents provide increased air circulation for extra coolness on warmer nights.
