Contact FoamNights

FoamNights is a small, independent, ad-supported site — there is no support team behind it, just email. If you spot a bug in a calculator, have a correction for an article or museum entry, or have an idea for a new tool, write to support@foamnights.com. We read everything that comes in, though there’s no fixed turnaround time we can promise.

What’s Useful to Mention

• Tool feedback: name the calculator (Sleep Cycle, Sleep Debt, Sleep Efficiency, Mattress Size, Mattress Firmness, or Caffeine Cutoff) and the inputs you used, so the numbers can be checked.
• Something broken: the page it happened on and roughly what device or browser you were using.
• Content corrections: a link to the page and what looks wrong, for articles, guides, or the Sleep & Mattress Museum.

What We Can’t Help With

This inbox can’t offer medical advice about sleep disorders, insomnia, or other health conditions — for that, please see a doctor or a qualified sleep specialist. We also can’t recommend or endorse specific mattress brands or retailers; the site isn’t affiliated with any of them, and the tools are built to be generic rather than steer you toward a particular product.
