The Cozy Prop 4-in-1 Sit Up & Prop Activity Mat  is must have. Well made material and design. Durable and easy to clean. Easy to store and to use. It helps promote growth with tummy time to practice sitting on.  Super easy to sit your baby up and it is very comfortable for them.  My baby loves looking at itself in the mirror and he likes to grabs all the different little  toys. Great for traveling. Highly recommend!
