About Cool Sleep Lab

Cool Sleep Lab started with a July 2024 power bill: $487, a 1994 Tucson ranch house running the original HVAC at full tilt, and a bedroom that still read 82 degrees at 4 AM. The fans weren't moving the number. The frozen-pillow trick had a ceiling. The "cooling" sheet sets were marketing copy on polyester. Something had to change, and the only way to figure out what was to start keeping records.

The site covers cooling mattress toppers, bed-climate systems, bedside fans, phase-change pillow inserts, and the other gear that ends up in a hot sleeper's bedroom. Every product listed here went through at least 30 nights of use on the actual bed before a review was written, with temperature logged three times nightly and watt-hour readings tracked for anything that plugs in. If the thermometer moved, the product gets a real write-up. If it didn't, the review says so.

Brian Caldwell runs the site. His background and how this project developed are on the author page.
