Check With a Professional When Needed
You are responsible for using your own judgment, and for seeking advice from a doctor or qualified sleep specialist, before making important decisions about your health, sleep, or a purchase. Our tools are designed to assist and inform, not to replace medical advice or your own judgment.
Tool Accuracy and Disclaimers
Calculation Accuracy
Our calculators and tools are provided for informational and educational purposes only. While we strive for accuracy, we cannot guarantee that all calculations will be error-free or suitable for your specific needs. Results are estimates based on standard sleep-science conventions and typical settings; actual outcomes may vary based on your body, your routine, and your individual sleep needs.

FoamNights makes no warranties, expressed or implied, and disclaims all other warranties including implied warranties of merchantability, fitness for a particular purpose, or non-infringement of intellectual property or other violation of rights.
Wellness and Health
Sleep guidance is general and informational only and is not a substitute for advice from a doctor or qualified sleep specialist. Persistent sleep problems can have underlying medical causes. Always treat results as general wellness guidance, not a diagnosis or treatment plan, use your own judgment, and seek professional care for any persistent sleep problem or suspected sleep disorder.
