Any store that sells home goods or bedding should carry them. Most manufacturers offer them in sets because it is more economical, not to mention easier, to pick up one package that has all bed-making components in it than two or three different ones and run the risk of picking different sizes. Check stores like Wal-mart, K-Mart, Sears and JC Penney at the mall or your local Home Goods and Bed Bath and Beyond stores. Good luck.

Do you mean a fitted sheet with elastic corners that

covers the mattress? I tend to buy the deep fitted

type as others come off.

Dunelm Mill stocks them in the UK.
