Wow- I really love this 4 in 1 activity mat!  My favorite feature is the ability to use it in so many different ways.  From prop up pillow to tummy time, my little one loves her play time.  The toy tray is great for both, and she really enjoys it.  This is huge for us because she doesn't prefer being on her tummy and this play mat really encourages her.  It's compact and easy to take on the go- great feature!  Overall love this- innovative design, great for tummy time, and portable....
