For complete protection, we recommend that you always encase your box springs. The good news is you don't have to spend a lot of money.
We carry several great covers perfect for box springs; heavy-duty vinyl (includes our patent-pending Bugstop® Seal tape closure), a stretch knit polyester boxspring cover or SMS polypropylene zippered encasings. All of these provide affordable options for complete protection. Zippered and fitted styles covers available.
