ECO COMFORT FIBRE : Our Eco Bunk mattress is designed to keep your little ones cool throughout the night. Our EcoComfort Fibre layer ensures the free flow of air to reduce moisture build-up and help to regulate body temperature, for a more refreshing and restful night's sleep. These fresh and comfortable fillings are biodegradable and kind to our environment. OPEN COIL SUPPORT : We know that often top bunk beds can creak and make a noise as your child moves, that's why our clever spring system absorbs movement for a quieter, undisturbed night's sleep. The highly supportive interlaced springs are joined together in a lattice design. Evenly distributing weight to relieve built-up pressure and improve spinal alignment. HYPOALLERGENIC : Free of allergens for a cleaner, healthier sleep. Helping to protect your children, the mattress is hypoallergenic which reduces the effects of allergy triggers including dust mites, mould and bacteria. UK’S MOST TRUSTED SLEEP BRAND: All our products are handmade in the UK and made to order, bringing you beautifully hand-crafted quality products, using the latest innovations.
