4. Operating Instructions
4.1 Standalone Bassinet Mode
In this mode, the bassinet functions as a portable sleeping space for your baby. Ensure the wheels are locked when stationary.

Figure 4.1: Standalone Bassinet Mode.
4.2 Bedside Sleeper Mode
This mode allows the bassinet to be placed directly next to your bed, providing easy access to your baby.
- Lower Side Panel: Locate the zipper on one of the long mesh sides of the bassinet. Unzip and lower the side panel.
- Adjust Height: Use the height adjustment mechanisms on the legs to match the height of your adult mattress. There are five adjustable levels.
- Position Bassinet: Push the bassinet flush against your adult bed. Ensure there are no gaps between the bassinet mattress and your adult mattress.
- Secure with Straps: Utilize the provided attachment straps. Pass the straps under your adult mattress and secure them to the bassinet frame on the opposite side. Tighten the straps to ensure the bassinet is firmly attached to your bed and cannot move away.
- Engage Brakes: Always engage the wheel brakes when in bedside sleeper mode.

4.4 Height Adjustment
The bassinet features five adjustable height levels. To adjust, locate the adjustment buttons on each leg. Press the buttons and slide the legs up or down to the desired height. Ensure both sides are adjusted to the same level for a flat sleeping surface, unless intentionally tilting for specific needs (e.g., reflux, under medical supervision).
4.5 Wheel Usage and Portability
The built-in silent universal wheels allow for easy movement between rooms. Each wheel is equipped with a brake. To move the bassinet, disengage the brakes. To secure it in place, engage the brakes on all wheels.
For travel, the bassinet can be easily folded and stored in the included carry bag.
