Frequently Asked Questions

  • What is the thread count for the Flannel Bed Sheets?

    Thread count is often considered an outdated measure of bedding quality because it doesn't accurately reflect the fabric's performance or feel. At Cosy, we prefer to use GSM (grams per square meter). GSM provides a reliable understanding of the fabric’s weight, density, and overall quality. Our Flannel Bed Sheets are rated at 165 GSM, ensuring they are cozy, durable, and of the highest quality!

  • What distinguishes the 100% Bamboo Bed Sheets from the Flannel Bed Sheets?

    The main difference is in the materials. Our 100% Bamboo Bed Sheets are made from 100% viscose derived from bamboo, making them exceptionally soft and breathable. Our Flannel Bed Sheets are crafted from 100% cotton flannel, making them super cozy and warm—perfect for staying snug during those chilly winter nights, especially if you live in a colder climate.

  • Will these sheets fit my mattress?

    Our flannel fitted sheets have a deep pocket that measures 15 inches. But thanks to the stretchy, flexible material, it can comfortably fit mattresses up to 17 inches deep.

  • Will these sheets stay securely on my bed?

    Absolutely! These sheets feature a 360-degree cinched perimeter around the opening and extra-wide elastic on the corners to prevent shifting during the night. Additionally, we’ve included corner straps for enhanced security and a snug fit for uninterrupted quality sleep.

  • How should I care for my Flannel Bed Sheets?

    Caring for our Flannel Bed Sheets is simple and hassle-free. Just place them in the washing machine and wash on cold with similar colors using a gentle detergent. Tumble dry on low heat and remove promptly to minimize wrinkles. Avoid ironing, bleach, and dry cleaning.

  • What is your return policy?

    We offer a Risk-Free Satisfaction Guarantee! If for any reason you are unsatisfied with your order, we encourage you to contact our customer service within 90 days and we will refund your entire purchase.
