What thread count means
Thread count describes the number of threads woven into a square inch of fabric. It is one characteristic of a sheet, not a complete measure of quality or comfort.
Choose with confidence.
A plain-English guide to cotton, thread count and fitted-sheet depth.
Good bedding starts with the right dimensions and clear material information—not the biggest number on the label.
Why fibre matters
Cotton is naturally breathable. Fibre quality, yarn, weave, finishing and care all influence how a finished sheet feels.
Why pocket depth matters
A fitted sheet must cover the mattress depth as well as its width and length. Include a topper in the depth measurement if it stays on the bed.
What 200TC offers
A 200 thread count cotton sheet can provide a practical balance of breathability, coverage and everyday easy care.
