Woolroom Natural Organic Temperature & Humidity Regulating British Wool Mattress Topper With Organic Cotton Shell - Helping you sleep at night

WOOLROOM Twin - Deluxe Natural Organic Temperature Humidity Regulating British Wool Mattress Pad Topper with Organic Cotton Ouer - Synthetic Alternative

The Woolroom is a luxury bedding company who specializes in all things wool, from comforters and pillows to mattress pads and toppers.

Their wool mattress topper is made from 100% traceable British wool, with a filling weight of 1000gsm and a depth of 4-5cm.

On the outside, you will find a 100% unbleached 300 thread count organic cotton shell with corner straps to help you attach it to your mattress.

Sleeping on this mattress topper is like sleeping on a cloud of puffy air. It’s soft and cosy, allowing you to drift off into sleep like a baby angel.  If you are looking for the “hotel bedding” feeling, this is a great option.

Unlike memory foam mattress toppers, it is a lot more compact, so you can take it with you if you are travelling.

They are new to Amazon, which is why (at the time of writing) there aren’t that many reviews, but there are loads of reviews on their own site, as well as all over other websites.

What makes them so special is that not only is their cotton GOTS certified organic, but their wool is 100% traceable, and sourced sustainably from British farmers who adhere to the “5 Freedoms” of animal welfare.

The 5 Freedoms specify that animals have:

  1. Freedom from hunger and thirst
  2. Freedom from discomfort
  3. Freedom from pain, injury or disease
  4. Freedom to express normal behaviour
  5. Freedom from fear and distress

I think that makes Woolroom pretty unique.

But if that hasn’t convinced you, their products are also sustainable.  And it’s not just a buzzword, you really can compost or recycle the wool in this topper at the end of its life.

Their products are free from chemicals as the wool and cotton is unbleached and no harsh fire retardant chemicals are required since wool is naturally fire retardant.  

Wool is also naturally resistant to dust mites, making it hypo-allergenic.

So all in all, it’s as close to “natural” as you can get, making it a good choice for anyone with allergies.

Things To Consider When Buying An Organic Wool Mattress Topper

What Are The Benefits Of A Wool Mattress Topper?

The benefits include:


Wool has pockets of air in its fibers that hold onto heat or disperse it according to changes in temperature. The temperature regulation ability helps to keep you cool when it’s hot and warm when it is cold.

Moisture Wicking

Wool wicks away sweat from your skin to the surface of the fabric where it evaporates to leave you cool and dry.


Wool is organic and sustainable, meaning that the fiber is not only biodegradable but also readily available and can be naturally replenished without harming the environment.

Chemical Free

Wool is naturally flame-resistant and also resists bacteria, mold, and dust mites. This negates the need to use chemicals such as fire retardants and pesticides in the processing and manufacturing of wool mattress pads.


Hypoallergenic simply means unlikely to trigger allergic reactions. Wool is free of common allergens in bedding which include chemicals, the waste products of dust mites, mold, and mildew.

Pressure Points and Support

The soft springy nature of wool makes it conform to the natural curves of your body, giving you optimum support and pressure relief in the process.

Durable and Long-Lasting

The fibers of wool are tough and resistant to moisture, wear, and tear. With minimal care, wool toppers can last many years without losing their sturdiness, quality, and appeal.

Do Wool Mattress Toppers Make You Hot?

Wool toppers won’t make you hot because wool naturally adapts to changes in the environment to keep you cool when it is hot.

What Certifications Should You Look Out For When Buying Organic Wool?

Different wool certifications mean different processes pertaining to fiber composition, animal treatment, impact on the environment, and worker welfare. Some certifications may be recognized globally while others are local depending on where the wool product is made. 

Generally, for organic wool, you should look for Global Organic Textile Standard (GOTS), Responsible Wool Standard (RWS), and Oeko-Tex Made in Green. Oeko-Tex Standards certification features in wool as well as other non-organic products to certify that where chemicals are used, they respect the health and the environment.

Can You Wash A Wool Mattress Topper?

Being a natural fiber, wool can be washed. However, machine washing most wool toppers can be cumbersome owing to their bulkiness and can also increase the risk of stripping the wool of lanolin and disturbing the fibers. Most manufacturers advise against it and in any case, you can care for wool toppers without washing them for a very long time.
