BreathableBaby Breathable Mesh Liner for Full-Size Cots, Light Pink — 3mm Single-Layer Airflow Safety Cover

BreathableBaby Breathable Mesh Liner is a single-layer, 3mm lightweight mesh crib liner designed to allow airflow while helping prevent limbs from getting caught between crib slats.

Designed by BreathableBaby—the original brand behind breathable crib liners—this full-size liner is made from a fine 3 mm polyester mesh that balances air permeability with a soft barrier. It installs around a standard 52" x 28" full-size mattress using long and short panels so you can cover three or four sides, and it’s been independently tested to align with recognized infant bedding safety standards.

How does this mesh liner promote airflow while acting as a barrier?

The liner uses a thin, single-layer 3 mm knitted mesh that permits exhaled air and room air to pass through freely while providing a visible, flexible surface between a baby’s limbs and the crib slats. It avoids thick padding that can trap air, reducing the risk associated with bulky bumpers.

• 3 mm mesh thickness engineered for breathability and visibility
• Knitted polyester fabric that allows unrestricted airflow
• Single-layer construction—no padding or foam inserts
• Tested for compliance with ASTM F1917 bedding guidance

Will this fit my full-size crib, and how do the panels work?

The liner is sized for full-size cribs with a 52" x 28" mattress. It includes one long panel (11" x 111") and one short panel (11" x 82"), giving you the option to outfit three sides using the long panel alone or cover all four sides by installing both panels.

• Designed for 52" x 28" (132 cm x 71 cm) full-size mattresses
• Long panel covers both long rails; short panel covers an end rail for four-sided coverage
• Not suitable for mini cribs or solid-end crib styles
• Trim dimensions and tuck method compatible with most standard mattresses

How easy is installation and maintenance?

The liner secures with hook-and-loop fastenings and includes a 1" fabric trim to tuck beneath the mattress edge for a tidy, stable fit. It’s machine washable so you can clean it as needed; follow the included instructions and video for correct fastening and care.

• Hook-and-loop straps for adjustable, tool-free installation
• 1" top and bottom trim for mattress tuck and added stability
• Machine washable polyester—follow care instructions on the label
