Merino wool sleepwear and bedding

Falling asleep may be easier than you think with Merino wool.

A good night’s sleep has been shown to boost immunity, optimise memory and cognitive function and is important for managing anxiety, so it is worth prioritising.


Wool blankets and underlays for a better night’s sleep

Using wool bedding – such as Merino wool blankets and wool duvets – combined with wool underlays improves the quality of sleep for adults. This is beneficial because sleep quality and the ability to regulate body temperature decrease with age.

Adults sleeping on wool underlays sleep more peacefully and wake feeling more refreshedvii. Compared to sleeping on a cotton sheet, wool underlays provide greater diffusion of pressure points, better insulation and better perspiration absorption making it more comfortableviii.



Wool blankets have been shown to offer better thermal insulation, moisture transport, and moisture buffering than a cotton/acrylic blanket. Promoting a refreshing, restorative sleep through increased warmth, reduced loss of heat and promoting good circulationix.


Wool pyjamas for a good night’s sleep

Wool has superior thermal insulation, moisture transport and buffering properties compared with other fibre types, making wool pyjamas more comfortable to sleep in than sleepwear from other fibres.



Babies sleep better with wool

Sleeping on woollen underlays helps babies sleep more peacefully. The texture and thermo attributes of wool are thought to reduce stress in sleeping infantsi.

Research shows that newborns sleeping on wool underlays spend 8% less time making minor movements, 14% less time making major movements and are less than half as likely to cry when sleeping on woollen underlays compared to cottonii.


Restful sleep promotes healthy growth and sleeping on wool has been shown to positively influence weight gain in underweight newbornsiii,iv. Pilot programs of Merino wool sleeping bags for babies report newborn parents saying their babies slept better when in a Merino wool sleeping bag compared with other products.
