10 Best Cool Sheets 2025 in the United States

These King Size 4 Piece Bed Sheets from CGK Unlimited are made from high-quality brushed microfiber, which makes them ultra-soft, lightweight, and breathable. The material is polyester with a 200 thread count, offering a silky feel that many find softer than traditional cotton sheets. Their moisture-wicking property helps keep you cool, making them a good choice if you tend to feel warm at night. The deep pockets (up to 16 inches) make these sheets easy to fit on most modern mattresses, including thicker ones, which is great if you have a plush or memory foam mattress. They come with two pillowcases, a fitted sheet, and a flat sheet, providing a complete set for your bed.

These sheets are wrinkle-resistant and easy to maintain, as they are machine washable and designed to keep their look without much ironing. The dark grey color is neutral and stylish, suitable for various bedroom decors. Because the sheets are made of polyester microfiber, some people who prefer natural fibers like cotton might find them less breathable or a bit synthetic in feel. Additionally, while microfiber is durable, it may not be as long-lasting as higher-end cotton sheets over many years.

Considering the price, these sheets deliver excellent softness and comfort, making them suitable for adults, kids, or teens looking for a cozy, cooling bedding option that’s easy to care for.

Bella Coterie's Luxury Bamboo Viscose King Size Sheet Set is a solid choice for anyone who wants ultra-soft, cooling sheets that are gentle on the skin. Made from 100% organically grown bamboo viscose, these sheets feel silky and lightweight, which helps with moisture-wicking and breathability—perfect if you tend to get hot during the night. The 400 thread count combined with the sateen weave gives them a smooth, luxurious feel that tends to get softer after each wash.

With an 18-inch deep pocket fitted sheet, they can comfortably fit thick mattresses, including those with pillow tops, so size and fit won’t be an issue for most. Caring for them is straightforward since they can be machine washed and tumble dried without hassle. The sheets are also certified free from harmful chemicals, which is a nice bonus for those with sensitive skin or concerns about toxins.

One thing to consider is that viscose from bamboo, while very soft, may require gentle washing to maintain its longevity and prevent wear over time. Also, while these sheets are marketed as suitable for all seasons, very cold sleepers might want to add extra blankets during winter since bamboo fabrics tend to be more cooling than warming. If you want a breathable, moisture-wicking sheet set that offers luxury and a great fit for deep mattresses, this Bella Coterie set is a comfortable and eco-friendly option.

The Bella Coterie Luxury Bamboo Viscose Queen Size Sheet Set is crafted from 100% organically grown bamboo viscose, offering a silky-soft feel that many users find very comfortable. With a 400 thread count and sateen weave, these sheets strike a good balance between softness and durability, and they tend to get softer after each wash. One of the standout features is their moisture-wicking ability, which helps keep you dry and cool—great for hot sleepers or warm climates. Breathability is another strong point, as the bamboo fabric naturally allows air flow, contributing to a refreshing night's sleep throughout all seasons.

The deep 18-inch pocket on the fitted sheet is a plus, accommodating thicker mattresses and ensuring a snug fit without slipping. Care is straightforward: machine washable with gentle detergent, but users should avoid bleach and fabric softeners to maintain the sheets’ quality. On the downside, some may find bamboo viscose less crisp than cotton sheets, leaning more toward a silky rather than crisp texture. Also, while the sheets are hypoallergenic and certified free of harmful chemicals (OEKO-TEX 100), they may require a little extra care when washing to keep their feel and appearance.

This set represents a solid choice for anyone seeking luxury, softness, and cooling comfort, especially if you have a thicker mattress and prefer silky smooth bedding.
