The OH is wondering about getting a memory foam mattress topper, but there's two questions that have come up.
Thickness: Is a 1" thick one OK, or should that be actively be avoided in favour of a 2" one? Does anyone have a 1" one and regretted they didn't get a thicker one?
Has anyone had a problem with their topper moving around across the underlying mattress, over the weeks. I think it's supposed to be a bit like the way a rug will gradually "walk" across a carpet.
And - Any good deals to be had?
