Had to raise my seating level by about an inch and a half as eye level was just slightly off from the center of the screen. Im a Picture Quility freak and while there wasnt much of a difference, the extra inch and a half put my eye level at dead center of the screen and the picture is ever so slightly brighter.

I used 4 of the little rubber stands that Axiom sends with the speakers and put them under the feet on my sofa. also got a wood board that was about an inch thick and put it under the seat cushions so you dont "sink" down when you sit.
