Review on 🛏️ Milliard Memory Foam Pack and Play Mattress Topper by Maria Noble

I use it on Ingenuity Playground. As others have said it is quite soft and I was a little concerned for my 4 month old. However, using a stretched sheet strengthens him so much that he actually feels like a mattress in his "real" crib. If you just place the sheet on top of the foam mattress, the foam will shrink, becoming too small and leaving big gaps - however, if you place the sheet on BOTH the foam mattress and the included hard mattress, it works great! My baby sleeps much better with this mattress! EDIT: The foam mattress is the correct size ONLY when the playground mattress is in the up (crib) position. When the mattress is moved to the floor of the older children's play area, a significant gap is left - about 1 to 2 inches on all sides. Therefore, unfortunately, the mattress is not safe for the Ingenuity playground when you lower the bed.
