double duvet covers for kids

[NeverTalksToStrangers]

I'm looking for two double duvet covers for my 2 ds.

I've seen numerous ones for ds2 but ds1 is proving a bit trickier. He's 5 so I don't want anything too babyish or too grown up (or too expensive). He wants something colourful. I'd also like one that I could get some funky wall decals to match etc as a surprise. Ideally nothing too garish or specific character based.

I've looked online in Debenhams, next, dunelm, ikea, matalan, tesco, argos, homebase, marksys, john lewis, mothercare, asda, b&q, very, woolworths...

I do this all the time. Drive myself nuts.

Is there anywhere I have not looked?

Have you tried La Redoute or Vertbaudet? Not sure about matching stickers. I like them because their bedding us often 100% cotton.

I know you say you've looked there, but I got a nice set from Next recently. There were two covers in stripes; blue, red, green. Can't see why that wouldn't be suitable for 5yo. Easy to match with decals in those colours.
