Lay My Hat

Does anyone use microfibre or tencel duvets and can anyone tell the difference between them and hollowfibre once the duvet cover is on?

No difference whatsoever if I'm honest. I did pay extra for trademarked goods when I was in the UK, but that was probably snob value more than anything else. Now I have feather & down (don't have to worry about guest allergies any more ) but I can say that the John Lewis hollowfibre duvets were excellent and quite possibly stuffed with a branded fibre like Tencel anyway.
