Smartly styled, very sophisticated in looks with the smooth, elegant lustre of a dense 600 thread sateen weave, these pure, 100% cotton sheets and pillowcases softly flow over the bed, draping beautifully to deliver their almost-effortlessly luxurious appeal. The higher thread count gives this bed linen a refined, silky feel, with all the inherent breathability, moisture absorbency and temperature regulation of natural cotton. The design of the range includes an attractive, contemporary pin tuck cuff detail.
Available in a range of sizes, and a choice of colours, the Cotton Sateen 600 Count Flat Sheet is a classic choice, which many believe is essential for the well-dressed bed. It gives you those razor-sharp folds and tucks with perfection to create the classic hospital corners when used as a base (bottom) sheet. As a top sheet, it drapes beautifully over and around the bed, protects the duvet cover and can help regulate temperature through the night.
If you like the look of a longer draped top layer, choose a flat sheet one size larger than your mattress. Cotton Sateen 600 Count Flat Sheets can retain their luxurious appeal with a simple machine wash and light ironing.

I bought these sheets to replace the same quality fitted sheets, as I was fed up with the time it takes to iron the fitted sheets. These flat sheets are much easier to live with and just as comfortable as the fitted ones.

We're really pleased with this Sateen Emperor Flat Sheet. It's huge in size, perfect for tucking around our 41cm deep superking mattress instead of a fitted sheet. The fabric feels thick and soft as well. Before I found Belledorm I had ordered an emperor sheet from a brand we usually buy from, but the measurements and quality were off. This one turned out to be just right.
