When I was struggling to sleep in a heatwave, diving into a 6ft slab of memory foam didn’t exactly sound like the answer. Memory foam is renowned for trapping heat, and the more “sinky” the foam, the more heat you’d expect it to trap. Less comfort layer, more boiled marshmallow.
However, the foam used by Panda in its flagship mattress topper genuinely seems to break the mould. It has the cosy feel of conventional memory foam, but it eased my night sweats so well when I tested the best mattress toppers in summer 2025 that I named it the “best cooling topper”, beating rivals filled with airy wool and microfibre.
