Accredited by Which?™ and awarded the Which?™ Best Buy award for three consecutive years, the Sealy Nostromo Pocket 1400 is a luxurious pillow-top mattress built with modern materials, technological advances and years of know-how from the biggest bed brand in the world

With 1400 zoned individually pocketed springs, each designed to move individually to provide luxorious comfort and precise support for perfect spinal alignment and to help alleviate lower back pain. This independent movement also prevents roll together and ensure consistent support from edge to edge

The mattress has a deep soft layer of latex (known as Innergetic Latex, exclusive to Sealy) on the surface. It acts to instantly cradle the contours of the body, effortlessly supporting the spine and further enhancing the luxurious soft 'bounce-back' feel of the bed. In addition, this material is ideal for those with allergies, as dust mites and bed bugs cannot thrive in latex

Topped with a quilted, tactile, natural cover made from Tencel and Sealy Smart Fibres, which work together to maintain a comfortable heat and moisture level all throughout the night. It's naturally temperature-regulating and also ensures the reduction of bacterial growth, helping to retain the freshness of your mattress and endorsed by the British Allergy Foundation

The Sealy Nostromo 1400 provides remarkable award-winning luxurious comfort, breathability and pressure relief for a perfect night's sleep
