I am purchasing an entirely new mattress set, with a hybrid king-size mattress. I have a choice of what to set it upon and want something that has 8-10 degrees of elevation as I have used a wedge to accomplish this, but would prefer if the frame or foundation had this either adjustable or built-in. Are you aware of any “systems” that would accomplish this. Thank you!
Hi SeattleSlew,
Welcome to the Mattress Forum! 
Off the top of my head, it sounds like you are describing something like this BedsUp system.

That is EXACTLY what I am looking for.
You are a truly valuable resource. I hope people appreciate this forum!
Hi SeattleSlew,
I’m glad I could be of assistance. There may be other items available like this, but that was the one that first came to mind.
Thank you for the kind words!
