Linen fitted sheets cover the mattress – the special elastic band holds them in right place. It is important to measure your mattress before purchasing fitted sheets. You'l need the length, width and thickness to ensure the fitted sheet will pull snugly over the mattress and not be easily pulled off. Our fitted linen sheets are machine washable and actually get better with every wash – you can tumble dry them too if you need to. We prewash all our fabric for extra softness so you can feel like you are slipping into a cozy cloud of bliss.
