Frequently asked questions

What does 400 thread count mean for cotton sheets?

Thread count is the number of threads per square inch. For combed cotton, 400 is a sweet spot that balances softness, durability, and breathability. Higher counts (like 1000) may use multi-ply threads that can actually trap heat and reduce airflow.

Is combed cotton better than regular cotton?

Combed cotton undergoes an extra process that removes short fibers and straightens the long ones, resulting in a smoother, stronger, and more uniform yarn. This reduces pilling and enhances softness, making it superior for bedding.

What is the difference between percale and sateen weave?

Percale has a crisp, matte finish and is more breathable, ideal for hot sleepers. Sateen has a silky, lustrous feel and drapes better, but can be less breathable. Both are common for 400-thread-count sheets.

How should I care for my 400-thread-count combed cotton sheets?

Wash in cold or warm water on a gentle cycle, then tumble dry on low. Avoid bleach and high heat to prevent damage. Most sheets will soften over time and can last for years with proper care.

Do these sheets fit deep mattresses?

Many of our picks, like the L.L.Bean Pima Cotton and Parachute, have deep pockets (15-18 inches) to accommodate thick mattresses. Always check the product specs for pocket depth before purchasing.

The verdict

For most sleepers, the L.L.Bean 400-Thread-Count Pima Cotton Percale offers unbeatable durability and crisp comfort.
