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.
What is an organic mattress?
First thing's first:
What exactly is an organic mattress?
Marketing terms like organic, natural, non-toxic, and eco-friendly are often thrown around, but it isn't easy to ascertain what these mean.
And just because a mattress is advertised as organic, it doesn't necessarily mean that it is a 100% natural mattress. 🌱
If you see a mattress that's been certified as organic by an independent testing authority, then you know it is the real deal. 👩🎓
In general, this means the mattress:
- Is free from pesticides & chemical treatments.
- Doesn't contain harmful or toxic substances.
- Supports sustainability & reduces the overall carbon footprint.
While often more expensive, organic mattresses are available in a wide range of different materials, with a range of different properties.
So if you're looking for a high-quality organic mattress, it's possible to find the bed that's just perfect for you. 🥳
Organic mattress UK certifications
Since mattress brands can be unreliable, it's become imperative to look at mattress certifications. 🤓
If you buy a certified organic mattress that's been tested by independent authorities, you can rest assured that you are indeed getting a natural, organic, and eco-friendly mattress.
There are two popular organic mattress certifications used worldwide. 🌎
These are the GOTS and GOLS certifications.
Global Organic Latex Standard (GOLS)
Certified GOLS latex is produced in an environment where all materials and manufacturing processes meet strict global organic standards.
Global Organic Textile Standard (GOTS)
Certified GOTS materials are produced in an environment where all materials and manufacturing processes adhere to strict global organic standards.
What about foam certifications?
You're also likely to come across CertiPUR and Oeko-Tex certifications.
CertiPUR-US is a North American quality certification for foams. 🇺🇸
Certified foams have been independently tested in laboratories and certified as safe and responsible products.
Oeko-Tex standard 100 is a label that guarantees textiles are free of toxic products.
This includes toxins for the body and the environment.
Mattresses can be Certi-PUR-certified and meet the Oeko-Tex standards, but this does not necessarily mean they are natural or organic mattresses.
It simply suggests that they are chemical-free mattresses & do not contain any toxic or harmful substances.
If you're looking for a certified organic or 100% natural mattress in the UK, it's essential to consider the GOLS and GOTS certifications.
Do organic mattresses meet flammability standards?
To be sold in the UK, mattresses need to meet flammability standards. 🔥
Traditionally, there were two ways to do this:
- The surface of the mattress is sprayed or soaked in chemical flame-retardants.
- Flame-retardant foams, which often rely on PBDEs (polybrominated diphenyl ethers), chemicals, and other hazardous materials, are used.
Both of these methods involve the use of toxic chemicals.
The method used by most mattress brands today (natural and standard) is using fibre or fabric barriers to surround the inside of the mattress, where most of the combustible materials are located.
A silica base that wraps around the mattress (between the foam and the mattress cover) is the most common.
It melts in case of fire, smothering the flames. 🧯
Thistle and wool are more natural alternatives, both of which prevent fires in the same way.
Organic cot mattresses
While choosing an organic mattress may be an important lifestyle choice for you, it's even more critical when choosing a cot mattress for babies or toddlers.
Organic mattresses allow young children to breathe more easily and avoid the risk of allergies. 🤧
As with adult mattresses, it's important to consider external certifications.
