KPop Demon Hunters Derpy Merch: 4 picks from £12.99

The bedding is where the choice actually gets made here, and it is worth slowing down on. Two of the three duvet sets state their size in their own titles: one says double, another says single, and the Halantex set gives its measurements as a 140 x 200 cm cover with a 70 x 90 cm pillowcase rather than naming a size at all. So pull out a tape measure and check the duvet you already own against that figure, because the titles will not do the conversion for you and neither will I.

Fabric is stated unevenly. Halantex says microfibre; the two KPop Demon Hunters sets say reversible and two sided but never say what they are made of, which is the sort of thing you would want to know before it goes on a child's bed. Those two also both say officially licensed and both include a matching pillowcase, so the difference between them really is bed size, not features. The double is £34.99 and the single £29.99, a five pound gap that the titles justify only by the extra fabric.

If you are buying a gift rather than kitting out a bedroom, the Funko POP! of Derpy with Sussie at £12.99 is the one entry here that needs no measuring and no guesswork about materials. It is also the odd one out on a page otherwise given over to bedding, which may be exactly why it suits you.
