Disclaimer

Researched, not professional advice. SleepSetupCalc publishes calculators, dimension charts and buying guidance compiled from published manufacturer specifications, product listings, industry-standard sizes and the consensus of verified owner reviews. We do not test products in person.

Not medical advice

This site is not medical advice. A mattress, pillow, topper or base is not a treatment for a medical condition, and nothing here should be read as a diagnosis or a course of treatment. Persistent pain is a reason to see a clinician rather than to keep buying bedding.

Standards and conventions

Figures on this site are labelled as either an industry standard or a convention. Standards, such as US mattress dimensions and sheet pocket classes, are consistent between manufacturers. Conventions, such as replacement intervals, firmness by body weight and walking clearance, are widely repeated guidance rather than measured facts. A disclaimer does not make a wrong number right, so where a manufacturer does not publish a figure we return no value rather than estimating one.

Your own situation

Calculators here work from the numbers you enter. They cannot see your room, your frame or your mattress, and they do not know what a specific manufacturer rates a specific product at. Always confirm capacities, dimensions and compatibility against the documentation for the exact product you own or intend to buy before relying on it.

Assembly and load

Bed frames and bases carry substantial load. Follow the manufacturer's assembly instructions, use the centre support supplied, and do not exceed the weight capacity published for your specific frame.
