Having suffered with neck and shoulder pain since forever, when I came back to stay at my mum's house for Christmas, my neck was suffering due to the very unsupportive "support" pillows in my old bedroom. That's a lot of irritants to be putting your head and face on every night, especially since they can trigger allergic reactions in those with sensitive skin.

Our one disclaimer – this was one of our favourite toppers, but its slightly thicker profile means we’d recommend it for autumn and winter. He generally sleeps on his back and the thickness of this pillow is perfect for him, not too high or low.

There’s a staggering range of sizes – nine in total – and additional shout-outs go to the sustainable bamboo cover and the anti-slip straps in each corner, which ensure the topper stays put.Our V-shaped pillows are ideal for mums-to-be and nursing mothers as they’ll see them through their entire journey, providing the right support and comfort for their bodies.

We tested this during a week when it felt like the world (or at least Surrey, where the testing took place) was on fire – an unbearably hot week during which we’d ditched our duvet, and were keen to minimise any heat retention. Deploying a mattress topper might not require a PHD, but all too often these straps are needle-thin, so the thicker strips of material on this one were a welcome change. They add an additional layer of cosiness and can soften a firmer mattress, but they can become lumpy over time, therefore having a shorter lifespan than other types.It’s slightly on the thin side, so ideal for anyone who doesn’t want to add too much height to their mattress, although this didn’t mean sacrificing comfort – we were honestly blown away by the softness and support offered by this topper, and it was another one which was refreshingly true to size, too.

And if you’re unfamiliar, these additions to your set-up are essentially an enclosed wad of padding which add an extra layer of comfort to mattresses while also protecting it, and extending its shelf life.We’re assuming this is due to what Panda refers to as the hydro-foam core, but whatever term marketing decided to use, we love it. But in our defence, this wasn’t as easy as it might seem – the testing of the best mattress toppers took place during one of the hottest Julys on record, so we weren’t only able to assess the comfort levels, but each topper’s breathability temperature regulation properties, too. And after an especially horrendous week of sniffing and sneezing, the last thing we wanted was a mattress topper which would worsen our symptoms, so we were slightly wary about this duck feather and down mattress. Memory gel provided firm support without trapping body heat, and our neck and shoulders felt especially well-supported.
