Your box spring is also a breeding ground for dust mites and other allergens. Allergists recommend encasing the box spring since simple movements on the bed can cause these allergens to be released into the air. This is another method to ensure your bedroom is allergen free! You can purchase any of our mattress encasements and use it as your box spring cover if you prefer a more breathable or washable option. The mattress covers and box spring covers are made the same way. Vinyl covers are also an option for this application since they are more economically priced! Many new mattresses made today are deeper or thicker. As a result the manufacturers have reduced the height of the box springs in order to keep the total height from becoming too tall. Allergy Guard Direct has accommodated this by offering a low profile box spring cover made from the same Stretch Knit with Urethane we use in our mattress encasement line. Now you can have a nice clean fit without the sloppy excess those larger covers create.
