The SleepCurve mattress takes all the pressure off the back of the head giving the skull the opportunity to self correct. The mattress will prevent flat head from worsening and, in many cases, allows a more natural development of the head shape.  A recent study at Alder Hey Children's Hospital has shown that a SleepCurve® mattress is an effective and low cost treatment for positional plagiocephaly (Flat Head Syndrome).
