Attn, Hot Sleepers: Amazon Prime Day's Best Deals Were Made for You

Fitting mattresses anywhere from 8 to a whopping 21 inches thick, this padded mattress topper is designed to be moisture-wicking and fast-drying to prevent you from waking up in a puddle of sweat. What's more, though, is three-zone design, so each part of your body is ergonomically supported. (The wavy design at the top and bottom, for example, prevent the edges of your mattress from drooping over time, while the "cloud-like" quilting in the middle helps disperse your body pressure.)

Reviewers rave that the OEKO-TEX-certified topper is easy to put on your bed, and while it won't make you icy cold, it does a solid job of keeping you cool throughout the night.

Confession: I didn't want to believe the brand's claims this was the "greatest pillow ever invented" (brag much?). When I first tried it, I couldn't get over the $199 price. It was comfortable, sure, but could any pillow ever be worth that much money? Flash forward three years, and the pillow is just as plush and moisture-wicking today as it was on Day One—and my husband has stolen it. He loves it so much that he will sacrifice any necessity in our carry-on to ensure it travels with us.

Why? The Honeycomb Gelflex Grid really cradles and supports your head, so you never wake up with a neck ache—no matter how much you toss and turn—and its design genuinely keeps your head cool throughout the night. And during Prime Day, it's 20 percent off, making it an easier investment to swallow (especially since it seems like this pillow is rarely ever on sale).

Not ready for a $159 commitment? Consider these internet-beloved gel cooling pillows, which come in a pack of two and are 40 percent off—when you apply the coupon before adding 'em to your cart. They've racked up more than 241,000 reviews, with people raving about the breathable down filling that keeps these feeling comfy without trapping in heat, so you don't have to flip your pillow in the middle of the night. (The downside? Some say they start to flatten over time.)

An Amazon best-seller for their hotel-caliber softness (thanks, brushed microfiber) and affordability (again, thanks, brushed microfiber), these CGK Unlimited sheets fit mattresses from 8 to 16 inches deep, at a price that's hard to beat. You'll get a flat sheet, fitted sheet and two pillowcases, which are all lightweight, providing an airy breathability.

If you really want to make your room the coolest place to sleep, quite literally, you may want to look into a BedJet. This ventilation system can cool or warm your bed, depending on your needs, and it can be programmed to adjust the temperature by the hour. Plus, at less than six inches tall, the BedJet easily slips under your bed, largely hiding it from view.

Available in six colors, the Rest Evercool Cooling comforter uses proprietary double-sided fabric featuring fibers five times finer than silk, creating an ultra-smooth, cool-to-the-touch feeling blanket. You don't need a duvet cover for it, and if it gets dirty, you can simply toss it in the washing machine and let it air dry.

"I have a hot-skinned husband who leaves man shaped sweat stains on my sheets every night. So I looked into many cooling blankets in search for one that was 'fluffy' (his personal requirement)," an Amazon reviewer shares. "I haven’t had any man-shaped sweat stains in my sheets since he started using it either! So I can safely say its cooling properties are amazing!" (It's so effective, in fact, that she could only use it for about 20 minutes before she got too chilly, she adds.)

When my air conditioning broke earlier this summer, this handy little desk fan moved to my nightstand—and kept me from losing my mind on balmy nights. With five speeds, and an oscillating feature, it's very customizable, but what I really loved was its sheer power—it could really blow your hair back—and quiet hum. On its highest speed, it was still much quieter than my robot vacuum, providing a gentle white noise to fall asleep to (a surprising perk when you're sleeping with the windows open).
