A New Era of Sleep is Here.

We just completed the largest study of temperature-controlled mattress covers to date, comparing each person's sleep the week before Orion with their first week on it. Here's what we found after analyzing 2,394 nights of sleep

• Average sleeping heart rate fell 1.79 beats per minute.
• Overnight heart rate variability (HRV) rose 3.25 milliseconds.

The people who slept the worst gained the most.
Among those struggling most on each measure before Orion:

• 13.1% more deep sleep
• 19.4% more REM sleep
• 33.5 more minutes of sleep a night
• 26% less time awake in the middle of the night

In the category's first sham-controlled study, where participants didn't know whether temperature regulation was actually on:

• 14.0% higher mental sharpness
• 11.4% better mood

Based on a preliminary exploratory study of 14 Orion users.

Some people can't stay asleep. Some rarely reach deep sleep. Some just don't get enough hours. Averaging everyone into one number hides what matters to each of them. So for every measure, we looked at the 25% of people struggling most with that specific challenge and asked what changed for them. The answer was consistent: the people with the greatest need saw the greatest benefit.

Ask anyone who sleeps on a temperature-controlled mattress cover and you'll hear the same thing: I sleep better, I wake up better, I'm never going back. Past studies captured how people felt, but not what was happening inside their bodies. As one of the fastest-growing products in consumer health, this category deserves that answer.

Body temperature is the #1 controllable component of sleep quality, so we measured it. Each person was compared with themselves, before and after Orion, using temperatures they set themselves. On 73% of nights, beds started cooler and warmed toward morning.

Heart rate is how many times your heart beats per minute. A lower sleeping heart rate means your heart works less through the night, and in large population studies, a lower resting heart rate is associated with lower cardiovascular risk. Average overnight heart rate fell from 64.1 to 62.3 bpm (p < 0.001), and it fell in every group we looked at.

HRV measures tiny variations in timing between heartbeats. Higher HRV reflects a nervous system in "rest and recover" mode. It rose from 50.6 to 53.8 ms (p = 0.001).

Every sleep-stage gain above was significant at p < 0.001.

The main study had no control group, and participants knew they were on Orion, so factors like new-product excitement can't be fully ruled out. Grouping people by baseline also introduces regression to the mean (a rough week tends to be followed by a better one). Heart rate groupings held up well when we tested for this, but sleep-stage results deserve more caution. The sham-controlled study was small, with the sham week always first. Both studies are preprints that haven't completed peer review.

2,394 nights of data point in one direction: when your bed manages your temperature, your body recovers more. And the people who need better sleep most see it first.
