In bedding sheets, high thread count cotton bed sheets are key to achieving a good night’s rest. This is because higher thread counts result in a tighter cotton weave, making the fabric smooth and silky to the touch.

'The difference is in the weave,' says Aja Tilghman. 'Cotton refers to the overall material, where cotton percale is created through a crisscross weaving technique that results in a more soft, delicate, and durable feel.'

Silk is a natural fiber produced by silkworms and because it needs such delicate care in the production process, it tends to be a pricier option. Aside from the price, silk sheets are naturally hypoallergenic, but care and maintenance tend to be laborious.
