Sleep hygiene research suggests washing bed sheets, including fitted sheets, every one to two weeks under normal use. If you sweat heavily during sleep, have allergies, or share your bed with pets, washing weekly is advisable. Each wash removes accumulated body oils, dead skin cells, and dust mite allergens that build up in bedding over time. Having two or three sets in rotation makes weekly washing practical without putting excessive wear on any single set.
What thread count is best for fitted sheets?
Thread count is one indicator of quality, but not the only one. As a general guide:
- 200–400TC: good quality everyday cotton, breathable and durable
- 400–600TC: noticeably softer with a smoother finish, suits those who prefer a silkier feel
- 600–1000TC: premium luxury, hotel-quality softness with exceptional longevity
It is worth noting that thread count alone does not determine quality. Fibre type matters as much as count - a 400TC Egyptian cotton sheet will outperform a 1000TC sheet made from short-staple cotton in both feel and durability.
