Our Organic Stokke Sleepi Mini mattress has a pure 1.5" latex green rubber core with an organic wool moisture pad outer for total protection and dust mite control.  Easy to clean by just rinsing off outer.

Wool is used as a natural flame retardant and is naturally water & bacterial-resistant with dust mite control properties.  Quilted together and wrapped around the core, natural rubber is firmer than other natural type mattresses.

All of our crib mattresses pass all safety regulations and CPSC guidelines.

Synthetic crib mattresses are generally composed of a foam core with vinyl covering. A toxic, chemical laden mattress can cause irritation to nose, throat, eyes and can cause asthma like reactions or difficulty with breathing, potentially a factor in SIDS. Many studies have confirmed the link between SIDS and chemicals commonly found in synthetic mattresses.
