For something as basic as a mattress, the Athena 260 Coil Organic Crib Mattress does nothing in a basic, boring way. The interior features 260 individual coils, each composed of pliable 15.5-gague coil wire. Side air vents help keep the mattress fresh, and the exterior cover is triple-laminated with 100 organic cotton layers. The cover is also anti-bacterial, non-toxic, and water and tear-resistant. One side of the mattress is softer, making it appropriate for toddlers, but the other side features a firmer surface for infants. This mattress fits toddler daybeds, and meets and exceeds all state and federal flammability standards.
