This is not just any feather bed protector- these feature a silky soft 375 thread count cotton twill weave fabric. Our unique zipper system allows for easy linen changing. Oversized and gusseted to guarantee your feather bed (or fiber bed) will fit perfectly. Feather beds are simply too large to wash - so prevention is key. Using a feather bed protector allows you to simply remove the protector for laundering and re-apply when ready. This feather bed cover has a large zipper that opens on three sides and prevents dander, dirt and body oils from soiling or discoloring bedding. Feather bed protectors also help reduce dust mites, and provide cushion against feather bed quills.
