We got this mattress and our baby absolutely loves it. We did hours of research to find the right mattress and found this one checked all the boxes. Extremely breathable (I sampled myself) and soft and comfortable yet the right firmness. Of course it's a standard size so fits great in our crib and sheet sets and covers. So far we've even had a few accidents and the mattress is easy to clean and will hold up for years to come. Great investment!
