So many things! But here are a few:
Kids have a tendency to sleep hot which can prevent good sleep. We have a proprietary temperature regulating technology in the foam that helps kids sleep at their ideal body temperature for restful sleep.
Kids have lighter weight bodies, so we designed our support layer to have responsive foam for proper support.
Kids make "mistakes" so we made sure the fabric used on our cover is stain and water resistant, plus the cover is removable and machine washable with a heavy duty zipper
We only use safe materials including organic cotton in our textiles that are OEKO-TEX  certified and CertiPUR-US (r) certified foam.
