Why the Coo stands out for newborns
Unlike a traditional bassinet that you replace after a few months, the Joovy Coo starts as a snug rocking bassinet and grows into a roomy playpen. That means you get more use from one product, and your baby has a familiar sleep space even as they grow.
The breathable see-through mesh sides let you keep an eye on your little one from anywhere in the room. And because you can choose to let it rock gently or lock it fixed, the Coo adapts to your baby’s mood and your routine.
What you need before starting
You only need the Coo unit itself—no tools required. Make sure you have a clean, flat floor surface. Avoid setting up on a rug or uneven carpet, as the frame needs solid contact to lock securely.
Check that all parts are present: the frame, the bassinet/playpen fabric, and the mattress pad. If you bought the Coo as a bundle, you may also have a carrying bag or extra accessories.
Coo setup steps
- Unfold and lock the frame: Lay the frame on the floor and pull the two side rails outward until you hear a click. Push down the center hub until it locks flat. A common mistake is not pressing firmly enough—if the frame wobbles, the hub isn't fully locked. Check that all four legs sit flat and the frame doesn't fold back when you lift one side.
- Attach the bassinet fabric: Drape the fabric over the frame so the mesh windows face outward. Reach underneath and snap the fabric clips onto the frame rails, starting at the head end and working your way around. Ensure each clip is fully engaged—a loose clip can cause the fabric to sag. After clipping, run your hand along the top edge to confirm no clips are half-snapped.
- Install the mattress pad: Place the included mattress pad inside the bassinet, flat side down, and press the corners into the fabric corners. The pad should fit snugly with no gaps around the edges. A common mistake is using an aftermarket mattress that doesn't fit, which can create a suffocation risk. Always use the supplied mattress pad—it's designed for the Coo's exact dimensions.
- Choose rocker or fixed mode: At the base of the frame, you'll see a switch or lever. Slide it to the rocker position to let the bassinet gently rock when your baby moves. Slide it to the fixed position to lock the frame steady. A common mistake is leaving it in rocker mode when you need a stable surface for diaper changes or feeding. Use fixed mode for any activity that requires a still surface; rocker mode is best for soothing to sleep.
- Test stability before use: Give the assembled Coo a gentle push from the side and from the head end. In fixed mode, it should not tip or slide. In rocker mode, the rocking motion should be smooth and not too fast. If either feels off, recheck the frame lock and fabric clips. Perform this test every time you reassemble the Coo, especially after travel.
