Be sure to check Amazon for reviews of that tv pillow; lots of reviews for those kinds of pillows are not very good.
We have tried quite a few different types of pillows over the years. Down was our most expensive choice and also the pillow that has lasted the longest and been the most comfortable. Finally replaced my dh's after at least 20 years' of use with one from Bed, Bath & Beyond -- one of the few places we could find locally that carried good quality down bed pillows.
