Are cooling mattress toppers worth it?

If you’re a hot sleeper and sick of waking up in the middle of the night feeling swampy, then you don’t need to invest in a whole new mattress. Adding a cooling mattress topper is an inexpensive way to provide a more comfortable night's sleep while increasing comfort levels in other areas, such as pressure relief or support. If you live in a climate where the temperature can vary, you can simply add the topper when the weather gets warm and remove it when you no longer need it.

Cooling mattress toppers help maintain a comfortable sleeping temperature by using moisture-wicking or cooling fabrics and foams infused with gel, graphite, copper, or phase change materials. Latex is also popular among hot sleepers for its breathability.

Whether a cooling mattress topper is worth it largely depends on personal preference. Many hot sleepers will benefit from the improved sleep comfort and temperature regulation so they are worth the investment if you're not keen on purchasing a cooling mattress outright. Of course, a topper alone may not be a quick fix. You'll also want to pay attention to the bed linens you use, the pajamas you wear, and your overall sleep environment.
