State the intended bed size and measure each item in the set, such as a fitted sheet, duvet cover, and pillowcase. Use centimetres consistently and say whether the dimension describes the mattress, finished cover, or fabric laid flat.
Name the fabric composition only when the label or supplier information supports it. Count every piece and state whether a fitted sheet suits a particular mattress depth; labels such as "double" may not identify the exact measurements. Photograph the actual set and label each size or colour option.
If a set contains pieces of different dimensions, list them separately instead of giving one size for the whole package. Keep the product model and measurements together, and update photos when a supplier changes the fabric or dimensions. Ask buyers to compare their mattress measurements before agreeing a purchase.
