A hard truth: Linens can make or break a good night's sleep, especially if you have a high-quality memory foam mattress. When investing in the best sheets for memory foam mattresses, you'll want to keep your eye out for cooling sheets (all foam mattresses tend to be hotter than traditional pillow top mattresses) made out of lightweight and breathable fabrics like linen, cotton, or bamboo.
A bit about your mattress: Memory foam is incredibly dense (and you want it to be — that's what makes it so supportive). But because it's so dense, the material traps body heat, making it way more likely that you'll feel overheated as you're trying to sleep. This is where the best cooling sheets come in.
You have a few choices to consider when it comes to fabrics that breathe. Linen sheets are amongst the most expensive options (and wrinkle-prone, like linen clothes), but they are the top-tier choice for cooling sheets. If you'd rather save a few dollars, bamboo sheets are a bit less pricey and are breathable and naturally moisture-wicking. If you're going to go with cotton, look for a lower thread count. Not only is a thread count of 400 around the point where high-thread-count sheets tend to plateau in quality, but the higher the thread count the tighter the weave — so it's more likely to trap heat while you sleep. Somewhere between a 300 and 500 thread count tends to work best.
