Quick answer
Set up your Ultimate 3 bassinet by clipping it onto the stroller frame, then use the flat-lay surface for safe, comfortable naps on the go. Always secure the harness and keep the bassinet away from heat sources.
Why the Ultimate 3 bassinet is a smart choice
The Ultimate 3 bassinet is designed specifically for the Mompush Ultimate 3 stroller, so it clicks into place in seconds without any extra adapters. The flat-lay sleeping surface is ideal for newborns, who need to lie flat for healthy breathing and spine development. The OEKO-TEX certified quilted interior adds comfort and peace of mind, knowing the fabric meets strict safety standards.
One trade-off to consider: the bassinet is a dedicated accessory, so it only works with the Ultimate 3 frame. If you have a different stroller, you'll need to check compatibility before purchasing.
Step-by-step setup and safety guide
- Attach the bassinet to the frame: Hold the bassinet with both hands and align the clips on the bottom with the connectors on the stroller frame. Press down until you hear a click. Check that both sides are locked by gently tugging upward. Common mistake: forgetting to verify the click on both sides, which can lead to an unstable attachment. Always do a quick tug test after clicking.
- Adjust the position for a flat lay: Ensure the bassinet is fully flat, as the flat-lay surface is designed for newborn safety. If your model has an adjustable recline, set it to the lowest position before placing your baby inside. Common mistake: leaving the bassinet slightly tilted, which can cause your baby to roll or breathe uncomfortably. Check that the surface is perfectly horizontal before each use.
- Secure your newborn properly: Place your baby on their back and use the built-in harness to secure them snugly, but not too tight. The harness should sit low on the shoulders and between the legs. Common mistake: leaving the harness loose, which increases the risk of your baby slipping or climbing out. You should be able to slide one finger between the harness and your baby's chest.
- Use the bassinet safely on walks: Only use the bassinet while the stroller is moving on smooth surfaces. Avoid rough terrain or stairs. Keep the bassinet away from heat sources like radiators or direct sunlight for extended periods. Common mistake: using the bassinet as a car seat or for overnight sleep, which it is not designed for. Reserve the bassinet for stroller walks and supervised naps.
- Clean and maintain the bassinet: Spot clean the quilted interior with a damp cloth and mild soap. Check the clips and fabric regularly for wear or damage. The 4-year warranty covers manufacturing defects, but not normal wear. Common mistake: machine washing the bassinet, which can damage the fabric and affect safety. Inspect the clips monthly and clean spills immediately.
