We previously had the twin size double sided naturepedic organic mattress for 7 years, which we were beyond happy with. We got a bigger bed and needed to upgrade to a full. Even though it is an expensive mattress, I insisted on sticking with naturepedic because it was important that our son was sleeping on a safe, organic mattress. It is comfortable, not to soft and not too firm. It did not have any funky smells once we unrolled it. Very happy with our purchase!
