Hi lynw, I uploaded a bunch of pics for you. (Link below.) The measurements are in there. The cushions are only 2" which is fine. Thicker would be nice too but then you might want to lower the height of the bench.

I do think the graduated height is good. The only thing I would do different is make the depth of the bench deeper. My space is small so I was concerned that it would look too crowded (if that makes sense.)

I love, love the drawers. They are so easy to access. I know I wouldn't utilize a hinged top bench. Love the ideas of the slots!!

Hope that helps and good luck!

You are the BEST!!! I so appreciate you taking the time to help me. If I read the drawing correctly they are 18high and 15 deep? Didn't see the measurements for the back. Guessing they graduate from 1 1/2" - 3". Thanks again. I may be back with additional questins after I show this to our builder on Monday. Thanks again!!!

Wow. Those pics aren't as clear as I thought. The bench is only 16" high. I think I told them to drop them because a standard chair is 18" high. So the 16" of bench plus 2" cushion equals 18."

Th box of bench bottom is 20" deep. The drawer is 17" accross. The depth of the bench (from the bottom of the angled back to the edge of the overhang is a little over 16". This where I wish it was deeper. I just measured a comfortable dining room chair and it is 18" deep.

The top of the backrest is 2" (the little cap excluded) and the bottom of the backrest is 4" (basically the bottom box which is 20" less the 16" deep seat leaves the 4".)

Good luck. Hopefully anyone else with banquettes will give you advice too.
