Pottery Barn Kids offers mattresses made by both Lullaby Earth and Naturepedic. We review both Lullaby Earth and Naturepedic. The Lullaby Earth mattresses ($199 to $380) appear to be discontinued mattresses no longer featured on Lullaby Earth’s web site.
Two Naturepedic mattresses are featured: the Organic Ultra Light 2 Stage ($349) and the Organic Oval Crib mattress ($219 intended for an oval crib like the Stokke Sleepi).
Pottery Barn Kids is also selling a Lullaby Crib mattress ($169), which is not made by Lullaby Earth (can they get more confusing?). This mattress appears to be made by Simmons, reviewed here.
