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 a mattress topper?
A mattress topper is a soft cushioning layer that enhances the feeling of your mattress. ☁️
It sits on the top of your mattress and promotes a more comfortable sleep for those lacking support.
A cooling mattress topper provides cooling benefits while also giving a softer feel to a mattress that feels too firm.
Do mattress toppers keep you cool?
The primary function of a mattress topper isn’t to keep you cool.
A mattress topper can have cooling properties, but its primary function is to promote comfort and relieve pressure.
Typically, a mattress topper is made from memory foam, wool, or latex, which have mixed results in cooling you down at night.
Yet, some mattress toppers are cooler than others and made with heat-absorbing materials. ♨️
Consider a cooler mattress
A cooling mattress topper isn’t a miracle worker.
If you have a warm mattress, then a cooling mattress topper won’t do much to keep you cool.
Memory foam mattresses create a warmer sleep and aren’t the best choice for hot sleepers. 🥵
It might be time to upgrade to a cooling mattress instead.

Cooling mattress pad vs a cooling mattress topper
A cooling mattress pad and a cooling mattress topper are two different products.
A cooling mattress pad (also known as a cooling mat) is a thin layer that goes on top of your mattress.
Unlike a mattress topper, a cooling mattress pad’s primary function is to reduce the temperature of your sleep. 🌡️
If you are an excessively hot sleeper suffering from menopause or night sweats, we recommend using a cooling mattress pad.
Though they don’t enhance the feeling of the mattress, they can make your sleep significantly cooler.
Cooling mattress pads contain a gel that absorbs heat and pushes it away from the body.
Some can also be refrigerated before use for extra coolness. 🧊

Are cooling mattress toppers washable?
Most cooling bed toppers aren’t safe for the washing machine.
This is because they are made with materials that may become damaged when in contact with hot water.
Mattress toppers can be bulky, so even washable mattress toppers will not fit in a standard washing machine.
However, the Dual Layer topper by The Fine Bedding Company can be separated into two pieces, making it much more machine-friendly. ✔️
Other mattress toppers may also come with a washable cover.
The mattress cover can be popped into the wash with your regular bedding and left to air-dry before putting it back onto your topper.
We highly recommend using a mattress protector alongside your mattress topper.
A cooling mattress cover will protect your topper and mattress from stains and bacteria build-up.
The best cooling mattress covers and protectors are made with natural fibres and will encourage airflow throughout the mattress. 🌱

Cool mattress topper prices
A good quality cooling mattress topper typically starts from around £100 - £150. 💰
Mattress toppers made with high-quality materials, such as the Simba mattress topper, are much more expensive.
Depending on the size of your bed, premium toppers, like the Simba topper, can set you back around £200 - £1000.
But how much should you spend on a mattress topper?
When choosing a topper, consider your budget, whether you really need a topper, and the warranty conditions it offers.
Investing in a pricier topper with an extended warranty could be worthwhile, as it signifies a higher quality product likely to have a longer lifespan. 🤞
