If you're struggling to get a good night's sleep during high summer temperatures, award-winning mattress brand Emma has slashed the prices across its cooling pillows.

You can get 25% off one pillow, and up to 30% off if you buy two together. For instance, Emma's Comfort Cooling Pillow is on sale for £60 — was £80. The bundle is marked down to £112 — was £160.

With temperatures still soaring past 30°C as the UK heatwave persists, it can be difficult to get your rest in hot and stuffy conditions.

Sleep expert Dr Deborah Lee said: “Warm weather can make your current sleep discomfort feel a lot worse. If your mattress is starting to sag, or your pillows feel like you’re lying on a sheet of paper, then your bed could be disturbing your sleep without even realising it."

What separates a cooling pillow from a standard option is that it's designed to regulate your body temperature by absorbing and dispersing excess heat. This is meant to prevent the pillow from becoming uncomfortably warm.

If you're looking to snag the deals, you have until 11:59pm July 27.

Save 25% on the Adapt Cooling Pillow from Emma

This pillow is meant to combine advanced foam layers for cool, supportive comfort throughout the night. Its Premium ThermoSync foam is designed to help regulate temperature, while the HRX Foam is supposed to cushion your head and neck to relieve pressure.

Plus, the soft, breathable foam top layer adds extra comfort, and the removable, washable knitted cover promotes airflow to help keep you cool, dry, and feeling refreshed while you sleep.

Made with a breathable, micro-elastic cover, this pillow is designed to keep you comfortable during hot, stuffy nights. Its Outlast cooling technology is meant to help regulate temperature by absorbing and releasing heat, while the plush Aerosoft microfibre filling is supposed to provide soft yet supportive cushioning for your neck and shoulders.

Plus, the removable inner layers let you easily adjust the pillow’s height and firmness, creating a personalised sleep experience.

Each Emma cooling pillow features four carefully designed layers — temperature-regulating foam to help keep you cool, a supportive foam layer for your head and neck, a soft comfort foam layer for added cushioning, and a breathable, removable, machine-washable cover for easy care.

The Cooling Comfort Pillow may be a better option if you're looking to manually customise its height. It comes with removable layers in a medium to soft support design.

Emma says on its online site: "Side sleepers can keep both layers for a fuller, higher pillow, while back sleepers can remove the thin inner layer for a lower profile. Stomach sleepers can remove the inner layer completely for the lowest setting. The microfiber filling adapts to your sleeping position and springs back as you move."

On the other hand, its Adapt Cooling Pillow is built to have medium to firm support.

The brand says: "Side sleepers can keep all layers for maximum support, while back sleepers can remove one thin layer for a slightly lower profile. Stomach sleepers can remove both thin layers for the lowest setting.

"In addition to the adjustable height, the pillow also has a soft side and a firm side—simply turn it over to choose the feel that suits you best."

Emma is known for being one of a slew of so-called bed-in-a-box brands, which roll and vacuum-pack all-foam or hybrid mattresses so they can be delivered without any hassle. Most of these companies will collect your old mattress and recycle it — saving you a trip to the tip.

They also sell some of the best mattress toppers in the UK, duvets, bedding, and more.

Buying a mattress online might seem riskier than heading to your local showroom. To reassure customers, the team at Emma offers a 200-night trial period on all mattresses from its online store.

If you're unhappy with the mattress at any point during the first 200 nights, you can organise for free collection and a full refund. That should reassure anyone curious about trying an all-foam or hybrid design.
