Sink into the Cygnus Pocket Sprung Gel Memory Foam Mattress for a night of deep, restful sleep in your own bedroom sanctuary. The individually wrapped pocket springs work with a layer of gel‑infused memory foam to gently hug your body, easing pressure from your shoulders, back and hips so you can drift off more easily. With responsive support that reduces motion transfer, you are less likely to feel every toss and turn from a restless partner, while the soft quilted top gives a cosy, cushioned feel from the moment you lie down. Thoughtfully designed for everyday comfort, this mattress features breathable side panels that help air circulate and maintain a fresher sleeping climate all year round. Integrated side handles make rotating the mattress simple, helping you keep it in good condition with minimal effort. Available in four popular sizes, the Cygnus Pocket Sprung Gel Memory Foam Mattress fits neatly into everything from a spare‑room guest bed to the main bedroom, making it a practical choice for any home that values reliable comfort and long‑lasting support.
