What a cooling mattress can do is stop the bed itself adding to the warmth.\u003c\/p\u003e\n\u003cp\u003eThat's worth knowing when you compare them. Gel can feel cool when you first lie down, then warms towards your body temperature as the night goes on. Springs and breathable covers let air move all night, so if you wake up hot in the small hours, airflow matters more than a cool first touch.\u003c\/p\u003e\n\u003cp\u003eSo check which cooling features a mattress actually has. One that combines several, such as springs under a breathable cover, is likely to do more than one relying on a gel layer alone.\u003c\/p\u003e\n\u003ch2\u003eWho needs a cooling mattress?\u003c\/h2\u003e\n\u003cp\u003eA cooling mattress is worth choosing if you regularly wake up hot or sweaty, share a bed, or sleep in a warm room such as a loft conversion or a top-floor flat.\u003c\/p\u003e\n\u003cp\u003eIf you only overheat during a heatwave, try a lighter duvet and an open window before you replace a mattress.
