The ASTM Firmness Rating is a standard measurement that helps you understand how firm or soft a mattress feels. It uses a scale to classify mattresses, making it easier for you to find one that suits your comfort preferences.
When shopping for a mattress, you might see a label that says 'ASTM Firmness Rating: Medium Firm,' helping you decide if it's the right level of support for you.
The ASTM rating refers to standards set by the American Society for Testing and Materials, which provide guidelines for evaluating the quality and safety of products, including mattresses.
A firmness rating measures how soft or hard a mattress feels, typically on a scale from 1 to 10, where 1 is very soft and 10 is very firm, helping consumers choose based on their comfort preferences.
The best firmness level varies by individual preference and sleeping position; generally, side sleepers benefit from softer mattresses (4-6), while back and stomach sleepers may prefer firmer options (6-8).
The hardness test according to ASTM standards measures the resistance of a mattress material to indentation, providing a quantifiable assessment of its firmness and support characteristics.
