There’s a few school’s of thought on this question. But what we’ve found is that by being able to sit on the side of your bed, and having your feet being able to reach the floor (heel and toes), keeps your body in a good posture, both getting in and out of bed. This tends to make it easier on your back and knees. If your existing bed isn’t this height off the floor, a good way to figure what is a good height is to measure by sitting on a chair that just gets your feet to hit the floor (heel and toes), and measuring that chair height (then adding two or three inches to compensate for your mattress compressing a bit as you’d sit on it). Then you can measure your frame height off the floor, then your foundation, then your mattress. If your mattress height off the floor is too high, then you can look into a lower profile foundation or a bed frame that’s lower. If your mattress height off the floor is too low, then you can look into a higher profile foundation or a bed frame that’s higher.
