I did quite a bit of research before purchasing this mattress. I asked a number of pediatricians and friends who have had kids and this mattress complies with most of the asks from pediatrician recommendations. I like the fact that it has two sides with different firmness. In all honesty, we haven't used it yet. However, my initial thoughts on this product are very positive. The overall built quality is noticeable at a quick glance, the mattress is very light weight, and the waterproofing material seems very durable. I am going to wait a few months and if I change my mind or if I think I need to update this review I will, otherwise, assume I still think this is a 5 start product.
