One of the hardest things for me to find has been a good back support. There are so many out there and frankly most are way overpriced for what you get. I have tried dozens and finally found one good enough to keep at my offices. It is called a Sitback Mesh Backrest and is perfect for any chair, be it in your home, office or car. The mesh allows for airflow to your back helping to keep you cool and comfortable all day. It is constructed of nylon which not only provides comfort, but maintains it's strength and resiliency. The best part is that they are made right here in the USA and their quality far exceeds that of their cheaper imitations.
