Do you have a long commute and your back is often killing you by the time you get there? It might have something to do with where and how you're sitting.
Car seat cushions are often uncomfortable and unadjustable. They don't have enough cushion to support the arch in your lower back (lumbar), which will make the muscles in your back and neck ache.
You might want to try a Klass Vaki Back Support Cushion. It can give you the added lumbar support you need.
It helps to protect and relax the muscles in your lower back, when you have to sit for an extended period of time. It also encourages proper posture and keeps the spine in its natural alignment with the extra padding on the sides.
Fit's Tips: You can use it in the car, at the office, and at home - you can even take it to the movies. It's not strapped in, so it can be easily removed and placed on a different seat. For $92, this might be just what your back needs.
