“The comfort elite adjustable base split king set gives you the adjustability you need to get comfortable. The base will help you sleep better with an older mattress too. With the adjustable lumber support, sags can be eliminated and provide a firmer lumbar area on worn mattresses. Additionally with the separate pillow and head adjustments you can angle your head up to watch TV in bed easily without raising too much of the upper body. Only bad thing I can say is the remote controls are not as responsive as they should be. You have to touch directly on the indicator for the item you want before the light will come on so you can see what you are selecting in the dark. This leads to hitting wrong buttons often just so it will light up to see what you want to select. Took off 1 star for that reason. One other issue is the location of the USB ports. They are not in a user friendly location and you would have to be out of bed to really use them which I don't anyway.”
