8. FAQ Section

Memory foam excels at pressure relief by contouring to your unique shape. This can significantly increase comfort by eliminating “hot spots” where weight is concentrated, though some users find the material retains more heat than cotton or wool.

The typical adjustment period is 7 to 14 nights. During this time, your muscles are “re-learning” a neutral posture. Initial soreness is common as your body moves away from the compensation patterns it used with your old pillow.
