Unlocking the science behind a great night’s sleep…

We teamed up with AWAKE — an independent specialist team of academics who study sleep and fatigue — to test our new Eco Comfort Breathe mattresses against the key factors behind a quality night’s sleep.

In the study, we used participant observation and leading sleep technology to discover how Eco Comfort Breathe fared against volunteer’s existing mattresses.

Studies show Eco Comfort Breathe mattresses could help you…

Fall asleep faster

Awaken less in the night

Enjoy better quality sleep

Reduce night-time overheating

Innovative sleep monitoring watches

Innovative sleep monitoring watches

We used intelligent wrist-worn sleep monitors, which have been specially designed to track sleep-wake patterns to track sleep quality, night-time awakenings and time taken to fall asleep.

Sleep monitors took recordings every 30 seconds and found that participants:

  • Experienced a 30% reduction in night-time awakenings
  • Fell asleep 33% faster

Participants also had their sleeping environment monitored for humidity and temperature using data recorders placed in their beds.
