What a mistake I made! I searched for a "double", deep, fitted sheet and lots came up. This particular one caught my eye with the 30cm corners and just what I wanted. Little did I realise that Wayfair have all kinds of sizes for a double! It does not fit across the bed, it is not a standard double and only fits on one side of the bed. I had to make up the bed for visitors and apologise to them for the ill fitting sheet. It didn't come anywhere close to a double. I would advise buyers to check your bed measurement because I put double and got a badly fitted sheet concentrating on the 30cm deep fitted sheet! A double is a double not a bit cut off to fit the sheet. Everything else I ordered was great.
