Guardmax Premium Box Spring Cover Full XL - Waterproof, Zippered

In this review of the Guardmax Premium Box Spring Cover Full XL, the bottom line is simple: this is a practical, no-frills encasement for anyone who wants reliable waterproof and bed bug protection for a box spring. It is aimed at buyers who already protect their mattress and recognize that the box spring is equally vulnerable to moisture, spills and pests. The product's strongest selling point is the full, six-sided zipped enclosure that keeps moisture, dust mites and insects out while fitting a Full XL box spring with a smooth, durable outer fabric.

Key Features

• Zippered Protection: A smooth gliding, tight locking zipper fully encases the box spring to block pests and debris on all six sides.
• Waterproof Inner Layer: A waterproof backing protects the box spring from spills, humidity and moisture that can cause damage over time.
• Full XL Fit: Sized for a Full XL box spring so it fits without bunching and covers the entire surface and sides.
• Durable Outer Fabric: Smooth, soft and durable material stands up to regular handling and keeps the encasement comfortable to the touch.

Who It's For

The Guardmax cover is best for households in humid climates, pet owners, or anyone who wants to protect a box spring from moisture buildup and insects without replacing the underlying unit.
