Couples struggle with this all year round, as one party may be warm while the other feels cold. While you can invest in separate duvets, portable heaters, and/or fans, this doesn't solve many of the issues that can arise from one person preferring to be cosy and toasty when falling asleep, while the other fancies a chillier rest.

That's where this smart mattress topper could be a great solution to the perfect night's sleep, letting couples sleep together all year round without compromising.

This Pulsio Thermasleep mattress topper is an innovative addition to your current mattress. It lets you customise your bed's temperature, with the ability to set each side to different settings to best suit both people.

This mattress topper can plummet as low as 12°C or heat up to a snuggly 55°C, making it a perfect bedroom addition for every season. With both cooling and heating settings to adjust, the Thermasleep seamlessly adjusts to your optimal sleeping temperature with its automatic sensor, or can be set to your ideal temperature.

With dual-zone capability, the Thermasleep allows each partner to set their own side's temperature, ensuring you no longer have to compromise on sleep preferences from season to season.

This mattress topper comes in a range of sizes, from Double to Super King, to suit your current bed and promises to fit over any bed like a regular bedsheet. You can also customise your mattress topper according to your preferences, whether you sleep alone or share with a partner, with the choice between solo-zone or dual-zone settings.

It isn't just saving relationships' snoozing; this mattresscould be a lifesaver for those who struggle with night sweats or overheating or feel the chill more than most. Your Thermasleep will automatically increase or decrease the temperature while you doze to ensure your body is never too hot or too cold.
