I bought 2 of these, but they were shipped separately at different times so it left me a little confused. I started a refund process, but when the second one showed up i canceled the refund process. I like these without the little nubby patch in the middle like many others have. I can use these in bed too with a fan behind the unit to keep my back cool when dealing with high stress gaming, or just to keep cool. Cant really put a fan behind them while in my car though as the curvature matches some what closely to the seats of my vehicle already. Still helps to keep cool and not get sticky-stuck to hot vinyl seats! !
