After going down an organic crib mattress research rabbit hole, this one clearly stood out to me as the best choice in terms of price and specs. I wanted one that was at least 5” high and firm. This mattress is comfortably firm, with a weight of 19 lbs. It is quite heavy and at first somewhat of a challenge to change crib sheets but I’m now getting the hang of it. For those with sensitive noses, it did have a very subtle wool smell upon unboxing but only because I was focusing in on it for review purposes. I actually enjoy that new product smell myself. The most important thing is that baby seems to like it and has been sleeping through the night on it (when she does wake up in the middle of the night, she is able to put herself back to sleep…something she couldn’t do on her old flimsy waterproof mattress). Hallelujah!
