On warmish nights I just pitch the quilt atop the mattress, leave the strappies undone, and use it like a, well, quilt, sticking legs or arms out as needed to dump excess heat. But on my last trip, which went down below freezing night after night, I wrapped the straps under the mattress and cinched the neck drawstring. I slept warmly, and never slipped nor slid off the mattress.
I turn a lot a night, being a side sleeper which causes the lower shoulder to get achy, and the quilt didn't turn with me, it stayed atop me without hassle.
I'm liking the flexibility of a quilt, and don't mind at all not having to carry a bunch of excess down and nylon which gets uselessly mashed under my body.
