While it may seem that a two-ply bed sheet would be a better choice with the greater number of fibers it contains, this isn’t usually the case. Two-ply sheets are often rougher and less durable, as cheaper materials are typically used. Focus more of your efforts on finding the right material and weave, but do try to stick with one-ply sheets.
A higher thread count simply means there are more threads per square inch, but what is agoodthread count depends on the style of the sheet. For example, good quality percale sheets usually have a thread count of 180 to 300, whereas good quality sateen usually have a thread count of 300 to 600. This is because sateen requires more threads, due to the weave style, than percale does.
Silk sheets feel really smooth and luxurious against the skin. Silk bedding is made from the cocoons of silk spun by silkworms. As with other natural fibres, silk is breathable and wicks moisture away from your skin to help keep you cool as you sleep. Like linen, silk has anti-bacterial properties.
