S/M5 1.4 metres square. Our contribution to encouraging floor play (on backs is just as important as tummy time) for babies and young children - and to providing bigger bodies with real comfort on the floor. The floor is an important work place for babies and young children. Here they move in all kinds of ways that will build strength, flexibility and the foundations for all kinds of future learning. These mats entice everyone onto the floor. Soft, squashy and so comforting. Available in BLUE ONLY at the moment.
