This product is DANGEROUS! Not only was it difficult to fold and unfold, but the seam on the sides spontaniously split in half after three months of purchase. I had only unfolded the product once, and my son was only seven months old, barely able to sit up on his own, so it was'nt the result of rough play. Also, the matress isnt safe. My sons leg had gotten caught underneath the padding. And the only thing I could fit into the travel bag was the playpen itself. I am shocked that this product is on the market and deemed safe. STAY AWAY FROM THIS PRODUCT!
