I recently purchased a KingSize Duvet 13.5 tog from Asda Direct. Went for the Egyptian Cotton Silentnight Duvet, and i have literally just got it out the packaging to put my new duvet cover on, and i was absolutely flabbergasted, what a waste of £32 i paid for it! It is soooo thin, and when in my new duvet cover, doesn't even fit! Seems to be a tad small, yes they are both Kingsize. So it is going back today! Browsing the Argos website and came across this Slumberdown one, more tog being 15 and at a bargain price of £14.99 (i paid £32 for the 13.5 tog piece of garbage from asda). So i have just reserved to pick up today! My boys have the slumberdown one but in single of course, so i know its a good duvet!
