We purchased this crib mattress to replace an older one. It hasn't been used yet (still waiting for baby to arrive), but I'm very impressed. There was no awful plastic smell when we opened the packaging, the newborn and toddler sides are clearly labeled, and the mattress corners are square so there's no gap between the mattress and crib. Mattress seems very durable and of high quality.
Here is additional information from the label:
-242 heat tempered, heavy duty 15.5 gauge steel coils
-Heat tempered 6 gauge border rods for extra strength and support
-Added support layer for extra firmness (infant side)
-Support layer for unsurpassed durability
-100% organic cotton layers for extra comfort
-Cotton fire barrier topper
-Jacquard fabric cover- anti-bacterial and water resistant
-Air vents help to keep mattress fresh
-Cloth binding helps prevent edge seams from splitting
-Meets all federal and state flammability standards...
