This new mattress is a pocket spring mattress. It is made of individual springs, each individually wrapped in cloth, each of them working individually to keep a firm and supportive surface, ensuring a comfortable sleep for your little one. This new mattress has been made with the same quality practices as our other baby cot mattresses, designed for your little one to sleep well and safely during those early months and years. It has been tested and approved with the Australian Cot Mattress Standards, AS/NZS 8811.1:2013. These savings are passed on directly to the customer. Meaning you can now purchase a better mattress at a better price.
