The SereneSleep Memory Foam Open Coil Mattress is designed for superior comfort and support. Featuring a traditional Bonnell spring unit, it includes a layer of high-density, next-generation open-cell visco-elastic memory foam that moulds to the contours of your body, relieving pressure and enhancing overall support. This helps to alleviate stress on key areas such as the neck, shoulders, hips, and legs, promoting a more restful sleep. The mattress is topped with a cool-touch micro-quilted super-soft fabric, creating a plush and soothing sleeping surface for ultimate relaxation. Carefully designed with breathable materials, it allows airflow to circulate freely, keeping the mattress cool, fresh, and odour-free. Hypoallergenic and anti-dust mite fillings further enhance its cleanliness and suitability for allergy sufferers. With a total depth of 8 inches (approximately 20cm), this mattress offers excellent anatomical support. Thanks to our advanced in-house technology and industry-leading packaging system, your mattress will arrive vacuum-packed, rolled, and boxed for convenience. We recommend unboxing within 7 days of receipt and allowing 24 to 48 hours for full expansion to its original size before use.
