no such thing exists - correct ?
you can buy a stretch knit mattress cover - and it would make sense to put directly over foam - except i don’t want to sleep directly over foam.
so if you are going to put a wool topper between a stretch knit cover and plush foam - it will then become the weakest link in terms of plushness - right ?
none of the wool toppers i looked at even claimed to be strechable. is this simply not possible with wool ?
by the way the ones i already have look like they will stretch permanently and never come back to their original shape.
