Whether you think your mattress is causing you to feel too warm at night or you don't find it comfortable enough, choosing to replace it can be expensive. But there are other ways you can improve your level of comfort and make your bed ultra-cozy. One relatively affordable way to turn your bed into a place where you love to lounge and sleep is to add a mattress topper—and this under-$70 on-sale find from Zinus has received more than 5,200 five-star ratings on Amazon.  

The Zinus 2-Inch Green Tea Cooling Gel Memory Foam Mattress Topper is designed to form around your body while you sleep and "[take] stress off of pressure points," according to the brand. Not only that, but the cooling sensation the mattress topper offers can help to regulate your body's temperature while you rest—and Amazon shoppers say it helps.

"This turned my bed from what felt like sleeping on a stretcher to a cloud," wrote one five-star reviewer who said the cooling gel inside the topper "makes a huge difference" before adding, "For the price, it's an amazing deal."

Since Zinus began creating bedding items, they note they have helped more than 18 million sleepers discover a new level of comfort. Plus, they try to create products that are environmentally friendly, so the memory foam included in the cooling gel mattress topper is CertiPur U.S. Certified. That means it hits the mark for things like "physical performance, indoor emissions, and environmental stewardship," shared Zinus. 

"This is the greatest thing ever, with not even a molecule of exaggeration," another shopper said. A different reviewer, who said they "highly recommend" the mattress topper, added, "It's so comfy, I hate to get out of bed."

Not every bedding item arrives ready for you to unroll and enjoy, but the Zinus Cooling Foam Mattress Topper, which is available in sizes twin to king, is different. After you buy one while the sale is live, you can start to experience your best, most cooling sleep (and relaxation) yet.
