An extra 2 hours of sleep, with reduced wake ups
One customer independently shared her sleep success story with us.
Months of sleep data generated while using a feather down duvet painted an uncomfortable picture of restless nights, repeated disturbances, and no real stretches of deep REM sleep. On average, she was getting 6 hours of broken sleep each night.

The data changed when she switched to an Ava Innes duvet. Her sleep was transformed. With the data from the app to prove it. Our customer was now benefiting from an extra 2 hours of sleep each night. Crucially, she was also achieving deep REM sleep. This was tracked for months, proving the Ava Innes sleep transformation was continuous.
This case study confirms what many of our customers tell us. That they are sleeping longer, more soundly, and with reduced disturbances through the night.
Why you should choose Ava Innes
How you sleep changes how you feel. It enhances and clarifies your entire wellbeing. For a long time sleep been seen as passive. But that's not the case. Sleep is active, restoring and healing both body and mind.
Here's why you should try our unique bedding:
-
Comforting weight. Cashmere guard hair is weightier than wool. This gentle cocooning feeling settles the body, sending sensory feedback to the brain that it is safe to unwind, to give in to sleep.
-
Excellent temperature control. Keratin is behind the science of why cashmere guard hair is so good at natural temperature regulation. It reacts instantly to the temperature of your body. Keeping you warm when you feel cold, and cooling you when you overheat.
-
Our natural approach. Inspired by the land, we believe healthy sleep is linked to the natural cycles around us. Like the ebbing and flowing of each tide, or the dark evenings that draw in during winter, sleep is ever changing. Choosing natural fibres brings us closer to this process, hand-in-hand with the gentle ethos and Ava Innes world we share rooted in our home in the Scottish Highlands. A world completely apart from technology that chases sleep with data and instant stats. By doing so, we don't force sleep. Instead, we create the conditions for it to unfold effortlessly.
