Anyone have an adjustable base for your bed? My gastroenterologist suggested I raise the head of my bed by six inches (put bricks or stack of boards under legs of bed) but my bed, mainly my mattress, is too heavy for me to do that easily. I tried a wedge pillow but found it to be so uncomfortable I couldn't get to sleep. I was wondering if an adjustable base would be a better, albeit more expensive, solution? Any pros or cons?
