How we test products
Our mission is to take the guesswork out of finding the perfect sleep products.
We've dedicated hundreds of hours to testing mattresses and sleep accessories, and rely on a team of testers of differing weights, temperature preferences, and sleeping positions to evaluate each product.
Tested products are granted the Sleep Hero tested stamp of approval, a mark of our review's reliability.
If we haven't personally tested a product, please be assured that we invest significant time and energy into scouring the UK market and researching the best recommendations, and we work with a team of sleep experts who review our articles, ensuring that the insights we provide are not only relatable but also reliable.
Are wool mattresses actually wool?
Wool mattresses are rarely made entirely of wool. 🐑
Typically, they are pocket spring mattresses with a wool layer on top.
For example, the Harrison Spinks Saltaire 10750 Pocket Mattress has a wool layer followed by a layer of cashmere, mohair silk, and pocket springs.
We dive into the different benefits of wool mattresses and their composition further down.
Who are wool mattresses suitable for?
Wool mattresses are comfortable, sustainable and suitable for a variety of sleepers.
Here’s a detailed look at who wool mattresses are best suited to. 👇
Wool is known for its natural thermoregulating properties, which we explained above.
This makes wool mattresses perfect for hot sleepers needing breathable and moisture-wicking mattresses.
Wool mattresses often include other cooling technology as well, like a breathable cotton cover or foam layer. 🧊
For example, the Simba Hybrid Pro mattress includes a layer of Simbatex foam underneath the wool layer.
Simbatex foam has an open-cell structure that allows air to flow within the mattress.
It’s also infused with graphite, a natural heat conductor that draws heat away from your body.
Wool is naturally hypoallergenic and resistant to dust mites, mould, and mildew, which are common allergens that can disrupt sleep. 🦠
This is down to wool’s moisture-wicking capabilities that keep your mattress dry, creating a less hospitable environment for bacteria.
This keeps the dust mites at bay and your allergies under control.
Wool mattresses are an excellent choice for individuals concerned about the environmental impact of their purchases.
Wool is a renewable resource, sheared from sheep annually without harming them.
It is biodegradable, meaning it will decompose naturally at the end of its life cycle.
Additionally, wool production has a lower carbon footprint than synthetic materials, making it a sustainable choice for environmentally conscious consumers.
Front and back sleepers
Wool mattresses tend to be firmer due to the natural resilience and density of wool fibres.
This firmness typically provides excellent support for front and back sleepers and helps maintain spinal alignment.
For back sleepers, the even support helps maintain the spine's natural curve, preventing the back from arching and causing you discomfort.
How much do wool mattresses cost?
Our recommended wool mattresses come at multiple different price points.
Harrison Spinks and Hypnos typically offer wool mattresses upwards of £2000, while Sleepeezee has a wool mattress for under £1000.
Simba and Millbrook sit in the middle, around the £1000 to £1500 mark.
However, all these brands offer excellent discount codes and deals around the big holiday events, like Black Friday, Cyber Monday and Boxing Day.
We will update you on the latest deals for our recommended wool mattresses on this page.
It’s also worth looking at the trial period and guarantee of your wool mattress before you click ‘buy.’
For example, the Harrison Spinks Saltaire Mattress and Millbrook Wool Luxury 4000 Pocket Mattress only come with a five-year guarantee and a 60-night trial period on Mattress Online.
In comparison, Simba offers an impressive 200-night sleep trial and a ten-year guarantee to thoroughly test your mattress and ensure you get your money’s worth over the next decade.
