Sleep. Grow. Thrive. The Thrive Kids Ortho Support Foam Mattress is designed to deliver firm orthopaedic support for children, helping promote healthy spinal alignment and proper sleep posture during key growth stages. Built with a durable 15cm foam profile, it offers consistent comfort, stability, and long-lasting performance for everyday use. At its core, high-density reflex foam (33kg/m3) provides structured support and even weight distribution, helping reduce pressure points while encouraging correct spinal alignment throughout the night. This firm orthopaedic design is specifically developed to support growing children with reliable, balanced comfort. The mattress features a smooth, non-quilted zip-off cover, making it easy to remove and clean, ideal for busy family households, sleepovers, and everyday practicality. Its hygienic design helps maintain a fresh sleeping environment with minimal effort. With a silent all-foam construction, this mattress ensures a completely noise-free sleep experience, free from springs or coils, making it perfect for undisturbed rest. Proudly built with durability and safety in mind, it is suitable for bunk beds, trundle beds, midsleepers, and standard single beds. This mattress also conforms to BS7177 British fire safety regulations, providing added reassurance for safe everyday use in the home. Viscotherapy Mattress Size: King (5')
