The adjustable sleep positioner helps to keep the baby in a comfortable sleeping position. Ideally, the back is well supported, legs elevated thanks to the shape of the cushion, and the head protector. It offers the most comfortable fetal position. By gently elevating the legs, it prevents reflux and any pressure on the stomach. It is made of breathable material, viscoelastic foam and polyurethane. Washable at 30°C.
