Best Cooling Mattress Protectors
Most mattress protectors trap heat — the waterproof membrane on cheap protectors is a complete vapor barrier. The picks below use either stretch-knit polyester or performance moisture-wicking fabric that lets the mattress breathe. If you sleep hot, sweat through the night, or invested in a cooling mattress like a Purple grid or Saatva HD, these are the only protectors that won't undo that cooling.
How We Ranked
- ✓Breathable construction — not a full vinyl/PVC barrier
- ✓Performance fabric or stretch-knit top surface
- ✓OEKO-TEX Standard 100 certified
- ✓Verified moisture-wicking or cooling claims from manufacturer
Our Methodology
We compared the top mattress protectors specifically marketed as cooling or breathable. Picks favor designs that pair a hypoallergenic waterproof membrane with a surface that wicks moisture rather than just blocks liquid. Crinkly plastic protectors and dense terry-cotton designs were excluded.

A soft fitted protector with two organic cotton layers around a thin, flexible moisture barrier. It prioritizes quietness and breathability for everyday spills; Avocado does not position it as a heavy plastic enclosure for prolonged liquid exposure.
- ✓Cotton layers soften the feel and reduce the crinkle associated with rigid plastic protectors
- ✓Thin flexible barrier preserves more airflow than a full plastic encasement
- ✓Two pocket-depth choices cover low-profile through tall pillow-top mattresses
- −Avocado says the breathable barrier is intended for prompt cleanup, not prolonged or heavy liquid exposure
- −Cotton shrinkage means the protector should be washed before use and may take several washes to settle
