I phoned Debenhams, and they said they did not supply this size, and suggested a King size fitted bedsheet, 152 x 200 cm. This is not quite what I want.
I could buy one from IKEA for 15 GBP. Frankly, I would like a more expensive and better quality bedsheet.
Is it safe to buy the low priced one from IKEA? Is it right to reject Debenhams which is the wrong size? Are there other retailers, online or in real life, who could have a better product than IKEA?
