Better in bed. Saves you 25% when you choose a bundle For a step above, the 600 thread count of the House Babylon Collection gives you an even softer, silkier feel. And because we use the same extra long staple Egyptian Cotton, you get sheets that look newer for longer. It’s all in the detail Buttoned Up: All our duvet covers come with buttons, bigger than the usual and harder to come undone. Fully Covered: All the pillowcases are envelope encased ensuring your pillows don’t escape. No escapes: All fitted sheets’ elastics are fully grippy. No more 3am bed making.
