Quick answer

Installing the G5+ Merino Wool Infant Car Seat Liner takes under five minutes: remove the existing liner, align the new liner with the shell, and secure it using the built-in straps and snap buttons.

Why the Merino Wool liner is different

The G5+ Merino Wool Infant Car Seat Liner is designed to replace the standard liner on your Orbit Baby G5+ Infant Car Seat. Its naturally fire-resistant Merino Wool blend means no added flame-retardant chemicals, which is a meaningful difference if you prefer fewer synthetic treatments next to your baby's skin. The fabric also wicks moisture and regulates temperature, so the liner handles heat and sweat differently than the original polyester lining.

Because the Merino Wool liner is thicker and more breathable, it may feel snugger at first compared to the standard liner. That is normal—the stretch in the knit allows it to conform to the seat over a few uses. Check that the harness straps lie flat and are not twisted after installation, especially during the first week.

Step-by-step installation

  1. Remove the existing liner: Unbuckle the chest clip and harness straps from the seat. Unsnap the existing liner from the shell at the shoulders and crotch area, then pull the liner out through the harness slots. Set it aside. Common mistake: pulling the old liner without unbuckling the harness first can snag the fabric. Always unbuckle first.
  2. Route the harness straps through the new liner: Lay the Merino Wool liner inside the seat shell. Reach behind the liner and push each harness strap through its corresponding slot from the back to the front. Make sure the straps come out straight, not twisted. Check each strap is not twisted before snapping the liner in place. Twisted straps reduce harness effectiveness.
  3. Snap the liner into the shell: Press the snap buttons at the shoulders and crotch area firmly into the corresponding receivers on the shell. You should hear a click for each snap. Smooth the liner from the center outward to remove any wrinkles. A loose snap can come undone during use. Double-check each snap by pulling gently.
  4. Re-buckle the harness and adjust fit: Reconnect the chest clip and harness buckle over the liner. Pull the adjuster strap to tighten the harness to a snug fit against your baby—you should not be able to pinch any slack at the shoulder. The Merino Wool liner adds slight thickness, so the harness may need a tighter pull than before. Readjust as needed after the first ride.
