As hot sleepers seek new ways to increase their comfort and quality of rest, some bed manufacturers are responding with a range of technologies and synthetic materials designed to lower the temperature of your sleeping environment. This is often done by adding a top layer of gel to absorb excess heat and maintain a stable temperature. If you judge these so-called cooling mattresses by their performance on the shop floor, you might be convinced, but David Henderson, director of Dreamwool Beds, encourages savvy Kiwi bed buyers to look a little deeper.
“Simplicity reveals and complexity conceals; if a mattress has lots of add-on features, you should be asking why they’re needed,” David says. “In many cases, the cooling mechanisms you see in high-tech mattresses are addressing problems created by flaws in the original mattress design.”
This is because substandard materials and synthetic foams fail to breathe, increasing the temperature of your bed and promoting night sweats. Adding a cooling layer on top of a synthetic mattress may mask these issues for a short time, yet as the night wears on, these gels can warm up and soften, leading to a hotter and less supportive sleep.
By contrast, Dreamwool Beds are made with generous comfort layers of the finest all-natural materials, including merino wool, renowned for its unparalleled softness, high fibre density, and moisture-wicking ability. “When it comes to temperature neutrality – an essential ingredient for a great night’s sleep – the key is breathability,” David says. “Chemically made synthetics, no matter how you dress them up, can’t provide that. Materials like memory foam lock in heat and don’t allow air to pass through.
A layer of cooling gel on top isn’t going to fix that.”
Unlike their synthetic alternatives, natural mattress materials absorb and disperse heat and moisture to maintain thermo-physiological comfort; this is where merino really shines. “Merino sheep thrive in New Zealand’s high country due to their natural ability to withstand a huge range of temperatures and climate conditions,” David says. “This means that their wool is uniquely suited for bedding due to its superior temperature regulation and moisture control, which will keep you comfortable all night and in any season.
“There is nothing better or more luxurious than the simple goodness of natural merino wool. Visit Dreamwool Beds at 96 Disraeli Street, Sydenham, to experience it for yourself.”
