Slumberdown Gel Memory Foam Mattress Topper, 5cm Upgrade your king size bed with the Slumberdown Niva Gel Memory Foam Mattress Topper, designed to add soothing comfort while helping you sleep more comfortably through warmer nights. The gel-infused memory foam gently moulds to your body to cushion pressure points, while the cooling gel technology helps draw away excess warmth for a fresher, more comfortable sleep. Ideal for summer, warmer sleepers, or anyone who finds standard foam toppers too hot. At 5cm deep, this king size mattress topper adds a supportive layer of comfort without feeling bulky, helping to revive an old, firm or tired mattress without the cost of replacing it. The body-hugging memory foam gives you that gently cushioned feel, while still allowing your fitted sheet to sit neatly over your mattress. The breathable knitted cover adds a soft, fresh feel, while the mesh sidewalls help airflow move through the topper, reducing the trapped heat that can build up with standard foam. It is a great choice for year-round comfort, giving you extra cushioning in colder months while helping you feel fresher and more comfortable when temperatures rise. Made in the UK with quality materials, this topper is CertiPUR certified and made without harsh chemical flame retardants, giving you added reassurance every night. It is also hypoallergenic, making it a suitable choice for sensitive sleepers. The removable cover can be unzipped and machine washed at 40°C, helping you keep your topper fresh and clean. Four secure elasticated corner straps help keep it firmly in place on your mattress, reducing slipping, bunching and movement through the night. You may notice a new foam smell when first unpacked; this is normal for memory foam and should fade after 24-48 hours of airing in a well-ventilated room.
