In some parts of the world, a second bed sheet is placed on top of the sheet that covers the mattress. This second sheet is referred to as a “top sheet.” When this top sheet is put in use, the sheet directly on the mattress is referred to as a “bottom sheet.” A sleeper lies between the two sheets. Blankets, comforters, and any additional bed covers are put above the second bed sheet.
When I shop for new sheets I always look for the ones with a thread count of at least 300. That is what bed sheets are like.
But to keep it simple, once you make sure you’re happy with the design and price, only check out when you’ve confirmed a thread count that is comfortable with you. As a guide the cheaper sheets made of cotton, muslin other cotton blends typically have a thread count of 150. This is what extra long twin sheets are like.
Bed sheets have historically been white, but in modern times many different colors and patterns are available. The quality of bed sheets is often conveyed by the thread count. The thread count is the number of threads per square inch of bed sheet material. Usually, the higher the thread count, the softer the sheet is. Common materials used in making sheets are cotton, linen, blends of cotton / polyester, silk, wool, rayon, and others.
A winter just isn’t complete without warm flannel sheets. Most people exclusively use flannel sheets in the cold months, because they will become “sweaty” in hot ones. In addition, many manufacturers have begun to produce flannel comforters and blankets to match the patterns on the sheets. This is what flannel sheets are like. Finally, a silk or satin pair of sheets is considered the ultimate in luxury. They are silky soft and will keep you from sweating in the summer. You can literally slide into bed and if you have a satin or silk pillow case, lay your head in pure luxury. The only downside to satin and silk sheets is that they tend to slide off of the bed if not fitted properly.
