These cooling mattress toppers, pillows, and duvets are the hidden gems of the M&S homeware sale - and they’re currently 40% off

If you’re a side or back sleeper you'll find the best pillow is a medium support pillow as they strike the perfect balance between comfort, softness, and much-needed support for your spine. This 2-pack of pillows in the M&S cooling bedding sale will also help you regulate your nighttime temperature, too. And for 40% off, who could resist?

No mattress would be complete without a mattress protector, and this M&S mattress protector is perfect for those who run hot during the night. Featuring Hydrocool® technology, it’s designed to wick moisture and regulate your body temperature to keep you comfortable and cool all night. It comes in four sizes: single, double, king, and super king.

A cooler sleep isn't just about opting for a breathable layer - like one of the best cooling mattress toppers - underneath your body. What goes on top is just as important. The M&S cooling bedding sale currently has four tog options to choose from in its Fresh & Cool duvet range. The most ‘heatwave ready’ option is the 2.5 tog, but those who find th summer evenings a bit chillier might find the 4.5 tog the best duvet.

This mattress was our E-Commerce Editor, Amy Lockwood’s, top pick. She said, 'We haven't tested this mattress, but looking at the construction, it has a couple of qualities that should make for a more breathable night's sleep, and breathability is key to a cooler night's rest. First up, the pocket springs will increase airflow throughout the mattress, drawing heat away from the body as you sleep. Next up, the inclusion of wool can be good news for a cooler sleep as this natural fibre is temperature regulating, and lastly the side vents should again allow any body heat absorbed by the mattress to dissipate throughout the night.'

A pillow protector can drastically improve how long your pillows last, but these aren’t just any pillow protectors. They’re M&S Fresh & Cool Quilted Pillow Protectors, which means that they have been designed to keep your head (and, in turn, your whole body) cool as you sleep. The construction allows for better breathability at night, as well as moisture-wicking properties, to help on those extra hot summer evenings.

There are certain things every side sleeper should look for in bedding, and firm pillows are one of them. Offering a firm but supportive night’s sleep, this 2-pack of pillows has been designed with Hydrocool™ technology to regulate your nighttime temperature and wick away any moisture that presents itself during sleep. These pillows are also antibacterial, which can really help you out if you struggle with hay fever during the spring and summer months.
