The support foam topper by Silentnight has been designed to provide both comfort and support when you are sleeping, helping to give you a better quality of sleep. The 3cm deep foam mattress topper features an innovative profiled design, similar to an egg box. The peak and valley shapes help to reduce pressure around the hips and shoulders as you sleep. Designed to relieve stress, joint pain, and muscle pain to help you get a peaceful and relaxing night’s sleep. Ventilated and breathable to allow air to circulate freely to prevent overheating. The support foam topper is hypoallergenic which means it does not contain any materials that are likely to cause allergies. The removable cover is machine washable at 40°C which means you can keep your topper feeling fresh and clean for longer. At Silentnight we understand the importance of a good night’s sleep and this starts with choosing the right bedding. We recommend that all mattresses should have a topper to increase the longevity and comfort of your mattress. Silentnight Bed Size: Kingsize (5')
