The simple truth is that the seats in cars are not tailored to individuals, which your back definitely notices on longer trips. The SpinePRO is designed to help keep you seated in an upright position by properly supporting the lower portion of your spine where most aches and pains occur. According to SpinePRO, the unique vertical control is fully adjustable, allowing you to literally lock in exactly the right amount of comfort to suit your specific needs. The product’s compact size means you can use it for other car seats and office chairs, etc. Order for $100 from www.myspinestore.com.
