The ProSource Shapes n' Colors Play Mat containing zero toxic phthalates is the ideal solution for creating a safe play area for children in areas with hard floors. Designed with your convenience in mind, the mat's coverage area is fully customizable and can be quickly assembled; use all 12"x12" tiles to cover 36 square feet, or use fewer tiles to protect smaller areas. For larger areas, simply purchase extra sets for seamless interlocking tiles. Made of durable high-density EVA foam that's slip and water-resistant, your child will have a durable non-slip cushioned surface to play on, while you have an easy-to-clean and maintain play area. Each tile has a shape that highly contrasts with the tile's color, making it easy for your child to learn and develop their cognitive skills. Worried about the play mat taking up too much space or having guests over? The interlocking design allows for quick dismantling, so you can stack them up for easy storage or simply move them into another room.
