Yield rating refers to how much a foam mattress compresses under pressure, indicating its firmness and support level. A higher yield rating means the foam is firmer and offers more support, while a lower rating indicates a softer feel.
When shopping for a mattress, you might see yield ratings listed in the product details, helping you choose between a firmer or softer mattress based on your comfort preference.
