April is known for its bedding sales, and mattress manufacturer Tempur-Pedic is offering one of the best mattress toppers on the market at a deep discount.

Through Monday, the Editor's Choice Tempur-Pedic Topper Supreme is on sale for $179. That's 40% off and one of the best mattress deals we've seen outside of the big holidays.

A good mattress topper can breathe new life into an aging mattress by adding a new layer of support and comfort. If buying the best mattress on the market is out of your budget, it is a great alternative.

We like the Tempur Topper Supreme because it allows you to add 3 inches of Tempur proprietary foam to your existing mattress. It's like buying a Tempur mattress, but without having to pay the full price. The Tempur Topper Supreme also comes with a hygienic cover that prevents mold, allergens, and dust mites. You can even remove the cover and throw it in the washing machine. Plus, it comes with a 10-year warranty.
