2.

3. Serta ThermaGel Cooling Memory Foam Mattress Topper: twin XL was $54 now $44 at AmazonSerta's trademark cooling ThermaGel is infused throughout this mattress topper to regulate temperature, while the foam is designed to contour the body in all sleep positions. A testament to how popular this foam bed topper is on Amazon, a twin-size is now sold out. However, you can still get a 20% discount on a twin XL, which gets you this bestseller for $44.
4. Molecule CopperWELL Mattress Topper: twin XL was $179.99 now $161.33 at AmazonDon't let the under-4-star rating fool you: we were seriously impressed with the cooling properties of this topper in our Molecule CopperWELL Mattress Topper review. We think it's perfect for both side sleepers and anyone who's going to a college in a warmer climate. The twin size is currently sold at Amazon but the dorm room friendly twin XL is both in stock and reduced to $161.33 (down from $179.99). While it's not as good as Prime Day's up-to-50%-off deal, this mattress topper is rarely ever on sale at Molecule so take advantage of the discount if you want high quality cooling.
5. Lucid 3" Gel Memory Foam Mattress Topper: twin XL was $74.99 now $66.28 at LucidAvailable in a 2", 3", or 4" height, the Lucid Memory Foam Mattress Topper was crowned the top budget bed topper in our Lucid Gel Memory Foam Mattress Topper review. Although the Prime Day sale has ended you can still enjoy money off a twin XL 3" or 4" topper, which is lucky news for college students and a saving you don't want to let get away. Right now the 3" topper is $66.28 for a twin XL, reduced from $74.99. Alternatively, if you keep a close eye on the Lucid site you can sometimes catch a flash sale on the mattress topper.
