Well, I would agree with some that they are a little on the expensive side. But after you play around for a few nights and get the thing adjusted, it really does help. Also, they are shipped in parts, not complicated, but it does require at least two people to get things put in place. If you get a thick one measure the legs on your bed frame. In our case we are planing to build a shorter frame. Ours worked out to be about 8" taller than the old bed. Not a problem really except every time I lay down I hit my head on a shelf built into the headboard. On the old bed the shelf was above the matress, on the new one it is at the same hight.It was fun watching the dog jump up there the first time. Seems over 10 years she kinda knew just how high to jump, then someone came along and changed it without consulting her. My wife laughed for hours.Getting older is just full of little annoyances, but the alternative doesn't look like any fun at all./w3tcompact/icons/laugh.gif
