Can't see the point if you've got to put a sheet underneath and a eiderdown on top.
And don't understand why having that hanging over your banister to dry is preferable to have a duvet cover hanging over your banister.
Also their 'all year round' duvet is only 10.5 tog rating. Far too low for me.
It takes a few minutes to put a duvet cover on.
Not something I'd buy.
