When we talk about luxury, we mean it; this mattress is a real treat. This mattress is at the height of technology with its pocket-air spring construction. This pocket-air spring system offers a glorious flexible feel via a mix of regular & shortened spring pockets. These springs work against your body's weight by increasing the volume of air to the mattress, so you're quite literally in sleeping heaven! Incredible support is offered through the pocket air system as it allows for even weight-distribution which ultimately gives you the maximum comfort possible. The use of wool & cashmere within the mattress allows for natural breathability & tempurature regulation. The added bonus? When working together with the side air vents, it helps keep you & your mattress fresh all night long. The core of pocket-air springs are enhanced by a pillow top layer of 1000 mini-springs to support your body for the perfect sleeping position. That's an impressive total of 4000 springs to give you a fully supported nights sleep. The pillow top not only has a cloud-like feel but also provides luxurious support. However the detail goes beyond the supportive spring system. This mattress uses a luxury damask fabric combined with cashmere along with hand tufting to firmly hold the fillings in place. Handmade in the UK by an NBF approved manufacturer, quality is assured & with eight handles to assist with regular rotation, it's easy to maintain.
