Rest Time Mats
Below are some suggestions for Rest Time mats that you can purchase via Amazon or Walmart! These contain an attached blanket and pillow. Since we store these nap mats here at school as well as send them home to be washed regularly, these type of nap mats work great as they roll up for easy storage.
