Did you know? Ordinary sofa mattress protectors only protect the top of your mattress. Why settle for just the top?
Our Sofa Mattress Encasement zips all the way around your mattress protecting it on all 6 sides!
Similar to our mattresses, this encasement can be made to almost any size or shape! If you don’t see your size listed, contact us for more information!

Dust mites can cause asthma, allergies, rhinitis, and eczema. They live on the millions of skin cells and body fluids that our bodies secrete each night while we sleep. Our sofa mattress encasement seals out dust mites and prevents any other allergens from coming into contact with your mattress!
The fitted sheet style sofa mattress protectors only cover 25% of your mattress, leaving you exposed to irritating allergens. Our 6-sided sofa mattress protector completely zips around your mattress to lock out dust mites and allergens!
It works so well that many of our customers leave their mattress encasement on their mattress during the off-season to give it an extra layer of protection!
Using our mattress encasement guarantees no fluids or stains will make contact with your new mattress! In fact, if you purchase a mattress encasement and a mattress from us at the same time, we offer you a lifetime warranty against spills and stains. If a spill or stain that goes through the encasement and on to our mattress and a professional cleaning company can’t get the stain out, we will replace our mattress with one of equal value for free!
The exclusive zipper lock system and our unique fabric has been lab tested to be bite and entry proof. This creates a fortress of protection around your mattress that works much better than a fitted sheet style mattress protector.
