You just have to decide which range of depth you want to buy? The Extra Deep fitted sheets are 15" (38cm) or the Ultra Deep 18" (46cm).
Due to the quantity of these sheets we are selling we cannot mix the colours I'm afraid, so if you order a double white fitted sheet, the second one free will also be white.
I know it sounds too good to be true, but just put one in your basket and you will actually receive two specialist extra deep 15" or Ultra Deep 18" fitted sheets for the price of one!
No matter how many sheets you put in your basket, you will receive double that amount, order 1 you will receive 2, order 12 you will receive 24.
