Frequently Asked Questions

  • What is the Luxury Mattress Encasement?
    • The Cosy House Luxury Mattress Encasement is a 100% waterproof cover that fully protects your mattress from spills, stains, and everyday contaminants. It acts as a physical barrier to prevent bed bugs, shields against irritants, and protects against everyday wear. The secure fit ensures your mattress stays protected while offering peace of mind.
  • How do I install the Mattress Encasement on my mattress?
    • Installation is easy! Just follow these steps:
    • Step 1: With the help of another person, remove the mattress from the bed frame and lean it upright.
    • Step 2: Unzip the encasement on all three sides and wrap the short, unzippered size over the top of the standing mattress. 
    • Step 3: Gently pull the encasement down so that both sides of the mattress are covered, and begin closing the zipper.
    • Step 4: Set the mattress back down on the bed and finish closing the zipper. Use the 360 Secure Velcro enclosure to seal off the end of the zipper.
  • What makes the encasement waterproof?

    Our Luxury Mattress Encasement is designed with a unique, double-layer membrane technology that absorbs liquids and shield your mattress.

  • What are the washing instructions?

    Wash on a gentle setting with cold water. Avoid bleach-based detergents to preserve the waterproof blocking of your encasement. Tumble dry low or air dry. Do not iron or dry clean.

  • What is the difference between an encasement and a protector?

    A mattress encasement generally has a zipper and six sides that completely cover the mattress for extra protection. Mattress protectors generally have five sides that cover the mattress like a fitted sheet.

  • 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.

“Immediately could tell the difference once I went to bed with the Luxury Mattress Encasement! So soft and cool, and it stayed securely on the edges of my mattress. There were no wrinkles after washing. I had never heard of Cosy before, but I will definitely be buying my bedding from them going forward after this purchase. Their prices are a win-win when you want a good rest.”

“This Luxury Mattress Encasement is so soft and does not shift. I was skeptical at first, but it hugged my mattress tightly and didn’t move an inch! I couldn’t even tell it was on the bed. I also love that it’s waterproof and doesn’t make any noise, too. I feel protected with this cover, and I’m very pleased with this purchase!”
