The SleepCurve® mattress is particularly useful for those babies suffering from torticollis. If the muscles in your baby’s neck are tighter on one side they are more prone to flathead syndrome. The space created in the SleepCurve® mattress allows your babys skull to develop naturally. The ability to move their head from left to right more easily on a Sleepcurve® mattress should also help loosen the stiffness in your baby’s neck.
