The review
Why we put this on the shelf.
Body temperature drops at night to trigger deep sleep — but most mattresses trap heat and prevent that drop. The Pod uses water-cooled channels to actively cool your bed (down to 55°F) and warm it in the morning to wake you up gently.
Built-in sensors track HRV, sleep stages, and respiratory rate. The autopilot mode adjusts temperature through the night based on your actual data.
We saw a measurable jump in deep sleep within the first week.
