We purchased this mattress to avoid the plasticky traditional crib mattress- 
And as such are very happy with it. Whilst still firm enough it also seems to have just a little give. It seems very comfortable and my baby has slept comfortably on it since night one. 

We would note that if you were meaning to purchase a mattress that was EXTRA firm, this one might not meet yor expectations. 

The price was reasonable and the shipping was very fast. 
We would definitely purchase this again or recommend.
