How Pillow Protectors Affect the Feel & Breathability of Your Pillow

By the CoolingPillows.com Editorial Team Criteria: 10-Point Pillow Spec Framework Sources: 18 Manufacturer-Verified Models

Because solid memory foam and Talalay latex cores cannot be machine washed, using a pillow protector extends the life of your pillow—but the wrong protector can trap air and alter firmness.

Avoiding the "Drum Effect" When Using a Pillow Protector

When your head sinks into a pillow, air inside the foam, latex, or shredded fill must escape. If a waterproof protector seals all six sides with an impermeable film, the trapped air balloons the cover taut like a drumhead, making a soft pillow feel stiff and warm.

How Breathable Gusseted Protectors Solve Air Trapping

Both the Coop Ultra-Tech Pillow Protector (Queen) and the Coop Ultra-Tech Body Pillow Protector (20 x 54 in) place a quiet polyurethane waterproof backing on the top and bottom panels while leaving the side gusset unbacked in a breathable polyester/rayon-from-bamboo mesh so air can exit laterally when compressed.
