BreathableBaby Breathable Mesh Crib Liner for Full-Size Cribs – Gray, 3mm Mesh, 3 or 4 Sides

Overview

BreathableBaby’s breathable mesh liner has stood the test of time since 2002, backed by scientific insight and ongoing research. The 3mm classic mesh uses A.C.T. Air Channel Technology to keep air moving while offering a light-dense barrier against crib clutter. The original liner has sold millions, reflecting a long-running approach to breathable crib bedding that many families have grown to trust.

What makes this liner stand out

• 3mm mesh with an 85% light-blocking rating balances visibility and airflow using A.C.T. Air Channel Technology. The fabric is 100% polyester with a neat 1" trim on the top and bottom, and it's machine washable.
• Flexible fit for full-size cribs: long panel (11" x 111" / 28 cm x 282 cm) and a short panel (11" x 82" / 28 cm x 208 cm) cover four sides, or the long panel alone covers three sides.
• Safety tested and trusted: independently tested to ASTM F1917 standards; contains no added chemicals, flame retardants, or formaldehyde.
• Breathable, non-restrictive design: a single layer of mesh allows exhaled air to pass through and reduces concerns associated with bulky bumpers.
• Easy installation: hook-and-loop adjustments; bottom fabric tucked under the mattress edge and all fastenings secured; review the manual or watch the installation video.

Fit, safety, and care

The liner measures 52" x 28" (132 cm x 71 cm) and is designed for full-size mattresses. Use four panels for full coverage or the long panel for three sides. Note: do not use on solid end styles or mini cribs.

Care and maintenance

• Machine washable for busy households; quick to refresh after spills or daytime wear.
• Durable construction with 1" trim helps the fabric maintain a secure fit around the crib edge.

In everyday use, the liner provides a breathable boundary that’s gentle on small arms and legs while keeping the crib feeling open and airy. The gray color and clean lines blend with nursery decor, and the lightweight fabric makes for easy handling during changes or moves.
