Thread count is the most abused number in bedding. After washing, sleeping on and grading six "Egyptian cotton" sheet sets, our verdict is simple: fiber origin and weave matter far more than the big number printed on the box.
Fiber and Weave, Not Marketing
Genuine long-staple Egyptian cotton feels dense yet breathable, and it holds its edge after repeated washes. Sateen offers that cool, silky drape with a subtle sheen; percale delivers a crisp, matte, welcoming hand that suits warm sleepers.
What Bought Comfort
The winning sets combined 300-600 thread counts with honest long-staple fiber — beyond that, counts are often inflated by multi-ply tricks. Deep pockets, secure corner elastics and low-pill finishing decided which sheets still felt new after a month of laundering.
