What is Thread count, highest stated?

Thread count is the number of individual threads woven into a square inch of fabric, counting both the lengthwise and crosswise threads. A higher stated count usually signals a smoother, more durable weave, though it says nothing about fibre quality or a brand's finishing. Avocado leads this group with a maximum thread count of 600 threads. Brooklinen follows at 495 threads, Birch at 320 threads, while bett1 and Brooklyn Bedding both top out at 300 threads.
