Protect pillow top queen mattresses during moving, storage, delivery, or warehouse handling with 60" x 12" x 90" 4 Mil Pillow Top Queen Mattress Bags. The 12" side gusset gives extra room for thicker mattress profiles, including pillow top and plush designs that need more clearance than flat mattress covers. The 4 Mil polyethylene construction helps resist punctures, scuffs, dust, and moisture exposure from routine handling. Each roll contains 40 bags, giving furniture retailers, mattress distributors, moving companies, and storage operators a practical pack size for recurring use without oversized case quantities. Butterfly vents help trapped air escape as the mattress slides into the bag, reducing ballooning and making the cover easier to position.
