Learn how to install a Cybex comfort inlay in your car seat or high chair. Step-by-step guide with tips for a secure, comfortable fit for your baby.

Quick Answer

To fit a Cybex comfort inlay, position it over the existing seat surface, align the harness slots, and secure the inlay with the provided clips or Velcro. Always check that the harness remains snug and the inlay doesn't bunch up.

Why Use a Comfort Inlay?

A comfort inlay adds an extra layer of padding and support, helping your baby lie in an ergonomically correct position. It's especially useful for newborns who need a snug fit in a car seat or high chair. The inlay also helps protect the seat from spills and wear.

Check Compatibility First

Not all comfort inlays fit every Cybex model. The Cybex Lemo Comfort Inlay is designed specifically for the Lemo Chair, while the Cybex Sirona G Line Newborn Inlay is made for the Sirona car seat. Check your product model before purchasing. Using the wrong inlay can compromise safety and comfort.

Step-by-Step Installation Guide

  1. 1. Remove the Seat Cover (if applicable): For car seat inlays like the Cybex Sirona G Line Newborn Inlay, first remove the existing seat cover. This ensures the inlay sits directly on the shell for a secure fit. For the Lemo chair inlay, you can place it over the existing cushion. Check your manual: Some inlays require removing the original cover; others don't.
  2. 2. Position the Inlay: Place the inlay on the seat, aligning the harness slots with the seat's harness openings. Make sure the inlay lies flat and covers the seat surface evenly. For the Lemo inlay, attach the backrest cushion first, then the seat cushion. If the inlay has a curved shape, the narrower end usually goes at the top or backrest.
  3. 3. Secure with Clips or Velcro: Most Cybex inlays have clips, straps, or Velcro to hold them in place. Attach these to the corresponding points on the seat. For the Sirona inlay, thread the harness straps through the designated slots in the inlay. A common mistake is forgetting to secure all attachment points. Check every clip.
  4. 4. Reattach the Harness: If you removed the harness to install the inlay, reattach it now. Ensure the straps pass through the inlay's harness slots and are not twisted. Tighten the harness to a snug fit against your baby's body. The harness should be tight enough that you cannot pinch any slack at the shoulder.
  5. 5. Test for Movement: After installation, gently push the inlay from side to side. It should not shift more than a centimeter. If it moves too much, re-secure the clips or adjust the straps. A loose inlay can cause discomfort and reduce safety. Test with your baby in the seat: the inlay should not bunch up behind their back or under their legs.
  6. 6. Final Safety Check: Ensure the inlay does not interfere with the harness buckle or chest clip. The harness should lie flat against your baby's chest and between their legs. For car seats, check that the inlay is compatible with your car seat's base and recline settings. If the inlay pushes your baby too far forward or changes the harness angle, it may not be suitable for your specific model.
