The Effect

What we measure

Deep sleep is when the body restores itself. We do not promise it; we measure it. With an Oura ring or a WHOOP band, offered at cost, you record at least four weeks on your current mattress, then eight to twelve weeks on your Vespera.

The Sleep Impact Report

Deep sleep, REM, heart-rate variability, resting heart rate and awakenings, before and after, with your own 1–10 answers beside them. Our goal: 8 or better on the 1–10, or a 20–40 % improvement within eight to twelve weeks. Ideally both.

Honest by design

The report shows the result as it is, including no change. It is yours. You may share it, with a face and a sentence, or keep it private.
