Butterfly's  Two Tone Mats set the industry standard for children's  rest mats. The heavy duty vinyl used on our Ladybug mat provides a soft sleeping surface and is designed with your children in mind. Ladybug mats have the quality characteristics that you have come to expect from Butterfly. Our Mat seams are sewn AND double stitched.  Our Mats contain a "high density" foam for comfort and are made right here in the USA. Ladybug Mats are a part of Butterfly's collection of "Mats that Last" and we back up this claim with a 3 year warranty. Additionally, Ladybug mats are tough, easy to clean, and most importantly provide a soft surface for your children on which to nap.
