"Thread count refers to the number of horizontal and vertical threads per square inch” -HGTV
Thread count is used to determine the quality of the bedding. The rule of thumb is as follows: bedding with a higher thread count means that it’s softer, more luxurious, and better quality than bedding with lower thread count.
But that is not always the case. Contrary to the popular belief, a higher thread count does to automatically mean that the bedding is better.
“A sheet of a better-quality fiber with a lower thread count will feel softer and stand up to washing better than a sheet of a lower-quality fiber with a higher thread count.” - Real Simple
A good example of sheets with high quality but lower thread count are bamboo sheets. These bamboo fibers are long, thin, and fine. That’s why bamboo sheets with lower thread count is comparable to cotton sheets with a higher thread count. With this, Bamboo sheets continues to provide the luxurious and soft feel that feels much like high quality cotton sheets.
Bamboo sheets are also naturally thermal-regulating, hypoallergenic, moisture-wicking, and odour-resistant. With this, you can have comfortable sleep throughout the night.
