Multilevel regression paired t-tests were test for statistical significance. Results There over 1,000 nights tracked across 25 participants.

Improvement also observed SleepScore, measure quality (p=.008). Self-report revealed greater when mattress, as well improvement variety perceived outcomes, time fall asleep, waking often, spending awake after initially falling longer duration, quality, feeling more rested morning (ps<.05).
