We love our back massager!! The neck massager is adjustable. It takes care from your neck to the top of your shoulders. There are two sections for the back. Upper section does a really good job on your shoulder blades and the lower section massages from the waist to your tail bones. The pressure is just right and it goes deep enough to massage the pressure points. Perfect addition to any office chair, study chair and even dining chair. The setup is super easy and versatile. Money well spent!
