It’s therapeutic for those who spend a lot of time in bed, or are prone to bed sores. This topper may also be helpful for those with fibromyalgia. It is incredibly healing, breathable and great for circulation.
Studies have shown that your heart rate is lowered when you sleep on a natural surface, resulting in a deeper sleep.
Natural Wool Toppers are great for not only creating a natural sleeping surface, but for softening a bed so you can sleep calmer and wake up feeling more refreshed.
Wool sleeps cool as wool creates a natural microclimate against your skin. Millions of wool hairs are like straws drawing away moisture from your skin and the millions of little curls contribute to the air flow and reduces pressure points.
History of Wool
Since the Stone Age, wool has been appreciated as one of the most effective forms of all-weather protection known to mankind, and science is yet to produce a fibre which matches its unique properties. Wool breathes, isolates, keeps off moisture, and it is temperature regulating and self-cleaning.
Here is an article I found on the internet you might enjoy reading. The author is unknown.

Wool has it all – naturally
Try as they may, scientists have not been able to produce a single fibre to match the properties of wool
There is a common misconception that wool is best suited exclusively for warmth in cool conditions. Scientific tests however negate this concept and consistently show that wool is ideal for apparel and bedding in hot, humid, dry, cold or wet conditions.
Wool has unique attributes, which give it superior performance to other fibers in a number of ways. Our bodies continually produce heat at a rate dependent on our activity level, this heat must be dissipated to the surroundings in the form of perspiration, at the same rate at which it is produced, to keep the body temperature constant1. When used in bedding wool creates a microclimate that assists in regulating body temperature and humidity. The degree to which body temperature and humidity is regulated is known as thermo-physical comfort, that is, a state in which the individual is free from thermal stress.
Freedom from thermal stress is directly related to degree of rest. There are a number of thermo- physical responses that can be measured to indicate how well rested a person is at any given time. Several studies examining and comparing the performance of wool blankets have consistently shown that in hot and cold conditions wool provides comfort and a more restful sleep than any other fibre type.
Umbach from the Holstein Institute in Germany, designed and undertook a series of studies to determine the measured responses which are most indicative of a rested nights sleep2. He found that first and foremost that the heart rate is the most accurate indicator. A person with a slow and regular heart beat is far more relaxed than a person with a fast pace and/or irregular heart beat. Two factors, which will be reflected in the heart rate, are the temperature and humidity of the bed microclimate. It is a well-known fact that in order for the major organs of the human body to function efficiently, the core temperature must be maintained at or near 37oC.
Using the thermo-physical responses related to sleep behavior, Umbach monitored several body and climate functions to compare the performance of wool versus acrylic blankets3. Subjects were monitored in environment controlled (temperature, humidity and airflow) rooms. It was found that the pulse rate of sleepers under wool blanket was normal at 60 beats per minute, where as it rose erratically up to 80 beats per minute under the acrylic blanket, indicating greater stress on the sleeping person.
This was easily explained by Umbach’s other observations: the wool blanket absorbed 50% more perspiration than the acrylic blanket, and cotton pajamas worn by the participant remained drier while they were under wool blankets. The microclimate under the acrylic blanket was too hot and humid for comfort.
The Ergonomics Unit at the Polytechnic of Wales compared comfort properties and sleep patterns of subjects sleeping under duvets rather than blankets4, again in an environment controlled room. When the bedroom was at 16oC, all sleepers were comfortable although the humidity under the wool duvet was lower. Interestingly, pulse rates under the wool filled duvets were again found to be lower than under the polyester filled duvets.
However, at 22oC the results were statistically discounted because the subjects under the polyester bedding exposed their limbs for periods of time in an effort to cool down. This response was poor substitute for the thermo-physically controlled microclimate as found under the wool duvet.
A third trial designed by P.R Dickson used the subject’s own room and bed as a control. Time-lapse photography monitored movement during the night to determine the sleep quality5. Dickson found statistically significant differences in the number of immobile periods, immobile sequences, and the percentage of the total time spent sleeping with the wool blanket compared with the acrylic surface. Again the wool blanket was proven to be the most restful surface to sleep upon.
The positive health effect of sleeping with wool is best illustrated by a study by Scott et al6 of low birth weight babies. This study found that babies nursed on lambs wool consistently showed a significant improvement in weight gain over and above those nursed by conventional methods using cotton.
Wool’s comfort advantages have traditionally been attributed to the capacity of the fibre to absorb a significant proportion of it’s own mass as water. Researchers agree that more than simply absorb, wool fibers have the ability to buffer by reacting to the humidity level within the particular environment. As the humidity rises, wool will absorb and store moisture as required. When the level decreases, the fibre releases the moisture thus regulating the microclimate. This property ensures that a damp, clammy feeling will never be experienced with wool. In this way, instead of the body regulating the microclimate, the wool bedding acclimatizes the body, ensuring a healthier rest with an even heart rate and blood pressure.
Another advantage of wool over other fibres is it’s outstanding insulating properties especially when compared with synthetic fibres8. The unique three-dimensional form of wool allows it to trap small pockets of air, thus giving it an insulating property. This property ensures that temperature changes are slow and gradual so that the bed’s microclimate has time to equilibrate. Rapid changes in heat loss or gain would hinder temperature and humidity regulation.
Wool’s natural resilience, is another property which aids comfort. The pile of an underlay will reduce pressure points and cushion the body. Tests using underlays with elderly and bedridden patients in hospitals have shown dramatic differences between the performance of wool and polyester bed pads. The following results clearly identify the advantages of wool.
Patients on wool had significant fewer skin problems than those on polyester pads. 77% of those on wool had no problems compared to 38% on polyester. Of those with debcutis, only 8% had a problem for more than one month while 38% on polyester had problems for a period for more than one month. In addition, no patients on wool pads had renewal of skin irritation once the initial problem had cleared up, while 14% had repetitive periods of irritation on polyesterb9. The health aspects of sleeping on wool continually outrank similar synthetic products.

An additional benefit to using wool products for bedding is the peace of mind in knowing wool is naturally resistant to ignition and is self-extinguishing. Perhaps the most dramatic demonstration of this was a trial developed to evaluate wool and polyester overlays to the British Standard B.S 7175. The ignition sources were, from one to six; a cigarette, 3 butane flames (the smallest of which represents a burning match) and 4 wooden cribs of various weights.
Results showed that the mattress assembly containing the wool underlay was capable of resisting ignition source 5, (wooden crib 16g) with no evidence of progressing smoldering. The polyester overlay however, when tested with a simulated match (ignition source 2) was found to act as a secondary source of ignition requiring extinguishing after eight minutes10. The ignition sources are numbered relative to their propensity to ignite the test material.
Wool with it’s unique physical properties is the ideal fibre for bedding applications, it has been subjectively and scientifically proven from a number of perspectives that wool has the advantage over other fibre types. Irrespective of whether wool is used for protection or comfort, its applications are suitable for conditions ranging from hot and humid tropics to the harsh and freezing Antarctic.
Wool has it all:-
-
- superior insulation
-
- resilience
-
- moisture absorption
-
- moisture buffering

Deeper, Longer, Better
Recently, a three-year study conducted at the University of Sydney showed that wool sleepwear promoted faster sleep onset than cotton sleepwear.
Differences in sleep quality also showed that a combination of wool sleepwear and bedding produced a deeper and longer sleep with participants waking less frequently.
Participants slept in Merino wool or cotton pyjamas, and under duvets of either cotton, polyester, or wool at three different temperatures: cold (17°C), neutral (22°C) and hot (29°C). The difference at high temperature was most marked.[1, 2]
Generally, the lower temperature, 17°C, was found to be more conducive
to sleep, and the findings highlight wool, next to skin, as an efficient insulator, researchers concluded.[1, 2]
An earlier study showed that periods of immobile sleep increased when participants slept on a fleecy wool underblanket. Participants reported feeling better in the morning and having improved sleep quality.[5] Similarly, when participants in another study slept on wool-on sheepskin underlays, they felt they had slept better. Researchers concluded that the wool pile diffused pressure points, provided better insulation to the sleeper, absorbed perspiration better than alternatives, and had a more reassuring handle.[6]
A Simple Way to a Good Night’s Sleep
Sleep is a vital aspect in the health and wellbeing of humans. Numerous studies have linked a lack of sleep to the risk of obesity, overall mortality rate, depression, and heart disease. Too little sleep can also affect the emotional development of children.
A simple way to a better night’s sleep may be to sleep on or under wool. There is evidence that sleep quality can be affected by the type of fabric of both bed linens and bed clothing.
Now, increasing scientific evidence of wool’s ability to improve
sleep quality.
Sleep Cool
Wool is effective in lowering the relative humidity at the skin surface, and to delay the on-set of sweating which results in smaller changes in core temperature. “Buffering” is the term used for the probable explanation for these smaller changes to core body temperature.
Buffering is a form of skin-clothing microclimate humidity control: As the rate of moisture evaporated from the skin increases, the relative humidity of the microclimate adjacent to the skin increases and the fibres respond by increasing moisture vapour content. This slows (or buffers) the rate of rise in humidity within the microclimate. As moisture levels decrease, the fibres give up some of their stored moisture, again slowing the rate of humidity change.
Each one of the hairs in the wool are like little curly straws that whisk away moisture and the springs reduce pressure points.
Even Babies Love It...Children sleep calmer
Weight gain in underweight newborns was 61% higher when they slept on a wool underlay instead of a cotton sheet, researchers have found.
Jaundiced newborns sleeping on wool were more settled and cried less than those sleeping on cotton, other research revealed.
In a study of Australian pre-school children on bedding fabrics and underlays, children who slept in any synthetic bedding in summer or winter
were more likely to be reported as having a sleep problem, than those who slept in cotton or wool.
