Our MamaDoo® Kids Smart Play Yard Mattress Topper

When we first became parents we were overwhelmed by all the baby products on the market: What do we really need? What is the best brand? One such item was our Playard/Play Yard/Pack n Play … a great invention, easy and fast to set up and transport. There was only one problem: that floor-board-mattress was just too hard and uncomfortable for our son to get any rest.

That’s when we decided to make something ourselves and our Smart Mattress Topper was born. It worked so incredibly well for us that we decided to share it with other parents who wanted to help their children (and themselves☺) in getting some rest too.

We measured every play yard on the market, determined the best size, experimented with and mastered the perfect design, found high quality non-toxic components, decided against manufacturing abroad and hired a manufacturer in California, USA, and off we went.

Many parents have written to thank us, because whether they are at home or on vacation, their baby is finally comfortable and everyone is more rested.

We are very proud of our MamaDoo Kids Smart Mattress Topper and believe that you and your child will be very happy with yours!
