10 Best California King Sheets 2026 in the United States

The CGK Unlimited California King 4-piece sheet set offers a soft, breathable, and cooling sleeping experience thanks to its brushed microfiber material made from 100% polyester. With a 200 thread count, these sheets strike a balance between softness and durability, and the double-brushed microfiber gives them a silky feel that many users find very comfortable—often softer than cotton options. The set includes a fitted sheet with deep pockets that fit mattresses up to 16 inches thick, a flat sheet, and two pillowcases, making it a convenient all-in-one solution.

These sheets are wrinkle-resistant, machine washable, and designed to be low-maintenance, which adds to their practicality. They are also Oeko-Tex certified, indicating they are free from harmful chemicals, which can be reassuring for those with sensitive skin or allergies. However, since these sheets are polyester-based, they might not be as breathable as natural fibers like cotton, and some people may find synthetic fabrics less comfortable in hot climates. Also, polyester sheets may not absorb moisture as well, which might affect comfort for those who sweat at night.

Despite these minor drawbacks, this set provides excellent value for its price, especially if you want soft, easy-care sheets with a good fit for deep mattresses. It is an ideal choice for families, guest rooms, or anyone looking for affordable luxury without the high cost of Egyptian or organic cotton.

These California King sheets by CGK Unlimited are designed especially for deep mattresses, fitting pockets up to 24 inches deep, which makes them a solid choice if you have a thick mattress or extra toppers. The set includes six pieces—four oversized pillowcases and the fitted and flat sheets—ensuring a complete bedding solution. Made from microfiber, the sheets are notably soft and lightweight, offering a smooth feel that might be a good change if you’re used to cotton. The 200 thread count is moderate, typical for microfiber, providing softness and durability but lacking the crispness some prefer in cotton sheets.

These sheets are breathable and wrinkle-resistant, making them easy to care for with simple machine washing and low-heat drying. However, microfiber doesn’t breathe as well as natural fibers, so if you tend to sleep hot, they might not be the coolest option. Despite the lack of specific hypoallergenic claims, microfiber generally resists allergens well, which can benefit sensitive sleepers. The color options and solid pattern keep things simple and versatile for most bedroom styles.

If you need sheets that stay securely on thick mattresses without slipping and want a soft, low-maintenance set, these are worth considering. But if natural materials or a higher thread count are priorities, you might want to explore other options.

These Pure Bamboo California King sheets are made from 100% organic viscose derived from bamboo, which makes them very soft and naturally breathable. The 300 thread count with a sateen weave gives the sheets a smooth, silky feel that tends to get softer with each wash. The sheets have deep fitted pockets (up to 16 inches), so they fit well on thicker mattresses without slipping off. Their natural cooling and moisture-wicking qualities make them a good choice for people who tend to sleep hot or have sensitive skin. They are also OEKO-TEX certified, meaning they are free from harmful chemicals, which adds a hypoallergenic benefit.

The set includes all the basics for a California King bed: a fitted sheet, flat sheet, and two pillowcases, all with double-stitched seams for durability. Care is straightforward with machine wash and low heat tumble dry instructions. One potential drawback is that viscose from bamboo, while soft and eco-friendly, may wrinkle more easily compared to cotton and might require some extra care to keep looking crisp. Additionally, while the 300 thread count balances softness and strength well, some users who prefer very high thread counts might find it less plush.

The included 2-year quality guarantee offers peace of mind. This sheet set fits well for those wanting eco-conscious, cooling, and silky soft sheets that work well through all seasons on a California King mattress.
