As paranoid first-time parents, we did a lot of research and decided on this mattress for our first little bundle (due in March, 2017). We were not disappointed! The mattress was delivered on-time and, as promised, is so light and did not come smelling of harsh chemicals. It fits perfectly snug in our Babyletto 3-in-1 Hudson convertible crib. The crib side is nice and firm and the flip side is comfy cozy! I have no doubt that it will stand the test of time! We lucked out, too, because at the time we placed our order, it just so happened to be cheaper through Wayfair than any other Canadian retailer.
