I'm a hot sleeper, so it doesn't usually take much to get me kicking off the sheets or turning my pillow over in search of the cool side, whether it's summer or winter.

However, when I became Ideal Home's Sleep Editor, all that changed. That's because I finally discovered the key to a cooler night's sleep, and it's all about your bedding.

That's why I'm sharing the six products I've tested that have made the biggest difference to my overnight temperature, *and* are often discounted on Amazon so you can snap them up for less.

1. Woolroom Deluxe Washable Wool Duvet

It's probably a bit dramatic to say my life changed once I added wool bedding to my bed, but it's effect on my tendency to overheat really was game-changing.

I discovered that the synthetic duvets I had previously slept under are made from materials derived from petrochemicals, which means that the filling shares many properties with a plastic bag! Instead, wool is naturally breathable. That means that body heat and humidity can dissipate through the fibres.

This Woolroom Deluxe Washable Wool Duvet may look a little utilitarian at first, but it's a staple on my bed that keeps me cool during the summer and warm during the winter. I think it's one of the best duvets for a hot sleeper, and I wouldn't be without it.

2. The Linen Yard Hebden Duvet Set

I used to choose my bed linen based solely on looks, but when I started learning more about what makes for a good night's sleep, that soon changed.

If you want to avoid getting too hot and sticky in bed, you need to ditch the polyester bedlinen and opt for natural materials instead. I'd generally recommend linen bedlinen for the coolest and most breathable sleep, but it tends to be very expensive.

A cotton duvet set, like this one from The Linen Yard, is a more affordable option that will still allow air to circulate for a cooler sleep compared to synthetic bed linen.

3. Silentnight Cooling Gel Pillow Pad

If you want to prepare for the next heatwave, this cooling gel pillow pad is one of my top recommendations for cooling down fast in bed.

It's designed to fit over a pillow – although I've also used it tucked under a bedsheet to cool down my torso when the mercury has soared – and features two compartments containing cooling gel.

This gel is designed to absorb body heat to help you sleep cooler, and it really works.

4. Woolroom Deluxe Wool Mattress Topper

There's a reason so many of us are searching for the best cooling mattress topper, and that's because synthetic and memory foam mattresses are prone to sleeping very warm.

Again, this is because the petrochemical-based materials synthetic mattresses are made from lack breathability. Adding a breathable mattress topper to your bed can act as a 'breaker layer' that allows for some air circulation between our bodies and the mattress.

A wool-filled mattress topper is a great choice as it's highly breathable which results in better overnight temperature regulation. Our Woolroom Deluxe Wool Mattress Topper review rated this option 4.5 out of 5 stars.

5. Simba Hybrid Pro Mattress

If you want the best mattresses to help keep cool in bed I would thoroughly recommend opting for a pocket spring mattress with padding made from natural materials for optimum breathability.

However, natural mattresses tend to be very expensive compared to synthetic options, and what's more many of us love the cushioning that a memory foam mattress provides, even if memory foam's dense structure can be prone to making sleeper's overheat.

Luckily, there is a way to get the best of both worlds, as long as you opt for a memory foam mattress that features open cell memory foam (that means there's more space between the viscoelastic fibres for air to circulate).

The Simba Hybrid mattress is one of the best mattresses we've tested in this regard featuring a hybrid pocket spring and open cell memory foam construction.

6. Woolroom Deluxe Washable Wool Mattress Protector

There's no point opting for a breathable mattress and then covering it with a non-breathable mattress protector.

You might not think a layer this thin could make a big difference to overheating, but when I slept on a memory foam mattress that regularly lead to my waking up hot and sticky in the middle of the night, I couldn't believe the difference made by adding this mattress protector to my bed.

Another Woolroom pick, this mattress protector is made from unbleached organic cotton quilted with washable 100% traceable British wool. It's not cheap compared to synthetic mattress protectors, but I do think it's one of the best mattress protectors you can buy if you're looking for a cooler sleep.

So that's it, my top six buys if you're looking to upgrade your sleep set-up for a cooler sleep!

If you're on the hunt for some bedding deals or mattress deals this Prime Day, I'd definitely recommend adding these cooling buys to your basket.
