I bought a second organic mattress for our second baby, after loving our first organic mattress so much, and because it was still in use by the first baby in her toddler bed. So happy that it is non-toxic and love how much more comfortable it is than the standard vinyl/foam chemical laden concoction and fits the crib perfectly and snug. I saw reviews on here about the mattress sagging, and I had to review that ours has not sagged at all - it is just as beautiful as it was out of the package 2 1/2 years later. And my son jumped, and jumped, and sometimes when the 2 year old AND the 4 year old jumped, and jumped on it like a trampoline night after night -- no sagging! Very happy with this company and product would recommend it to anyone new or used!
