Featuring Silentnight?s exclusive continuous spring system, this Miracoil Luxury Tufted Ortho mattress provides comfort and support for all shapes and sizes. Unlike an ordinary circular spring system, Miracoil's unique design has twice as many springs extending improved pressure relief, edge to edge support for maximum sleep space and zoned support right where you need it most. With a layer of Eco Comfort Fibres, this mattress is great for both you and the environment, as this comfort layer is made from 100% recycled plastic bottles which offers fresher, breathable comfort with enhanced airflow. This mattress is traditionally hand-tufted for long-lasting support and covered in a quality white damask fabric for a smooth sleep surface. This mattress is hypoallergenic to reduce the chance of an allergic reaction, so you can sleep without worry in a relaxing environment. As a single sided mattress, there?s no need to turn it, simply rotate for longevity. Mattress firmness: Firm. Made in the UK. Full 5-year manufacturer's peace of mind guarantee.
