This natural junior mattress is made without the use of chemicals, so you can be rest assured that your child is sleeping in a safe, natural environment. Each single sized mattress contains the best natural materials and is finished with a luxury quilted Herringbone cotton cover. This mattress is 90x200cm and 13cm deep to fit European size beds such as the Oeuf. It has firm lasting support that is suitable from 2-12 years. The Natural Junior mattress is made from the following natural materials. Coconut Coir - A deep natural core of coconut coir acts like thousands of tiny springs, reducing pressure points and providing an evenly sprung support. Natural Latex - This breathable layer of 100% pure natural latex (sap from the Hevea tree) creates a supple and comfy support that is chemical-free and extremely durable, withstanding even the most boisterous of children! Natural Fleece Wool - A wrap of naturally anti-dust mite, breathable fleece wool helps regulate your child's body temperature whilst dispersing any moisture to help ensure your mattress stays clean and fresh. Unbleached Cotton - A luxury quilted, non-removable and durable Herringbone cotton cover holds everything in place and aids the breathability of the mattress.
