A mattress pad can have a cotton sleeping surface and a different filling or backing. That is why a prominent “cotton” description should be followed by a closer look at the component information. The useful question is not whether a product hides a universal “polyester trap,” but which parts use which materials.

Read the component descriptions separately
Look for the top fabric, filling, underside and fitted skirt. If a waterproof layer is included, ask what that layer is made from too. Do not treat a fiber percentage attached to the cover as a description of the entire assembled pad.
For products sold in the United States, the FTC’s textile labeling guidance explains fiber-content disclosures for covered products. Its cotton advertising guidance also explains the importance of describing cotton content accurately. Use the physical label and component specifications together rather than relying only on a product title.
Ask for the missing information before ordering
If the listing only says “cotton pad,” request a photograph of its material and care labels. Ask whether the stated percentage applies to the surface, the fill or another component. Keep the response with the order so you can compare it with the delivered item.
For example, a hypothetical description of a cotton top with polyester fill describes two different parts of the product. It is not a statement that every layer is cotton. If your preference is cotton throughout particular components, name those components in your question to the seller.
Choose the construction that fits your priorities
Write down what matters most to you: a particular surface material, a certain amount of padding, washability or a separate waterproof barrier. Then compare products against the same list. Fiber content alone does not tell you the pad’s thickness, fit or washing requirements.
Measure the mattress depth, including any topper that will sit inside the fitted skirt. Check the pad’s stated fit range and whether its dimensions match your mattress. A material preference is only useful if the pad also fits securely and can be maintained using your available equipment.
Inspect the pad before washing it
- Compare the delivered labels with the advertised component information.
- Read washing and drying instructions before removing packaging needed for a return.
- Confirm whether the product is a padded layer, a protector or a combined design.
- Contact the seller if the component information is inconsistent or incomplete.
There is no need to assume that every blend is misleading. The goal is a clear description that lets you choose deliberately. Keep claims about any individual product tied to its actual label rather than generalizing from the word “cotton.”
