The Baby Jogger Second Seat Kit transforms the City Select 2 single stroller into a fully functional double stroller, accommodating two children with ease. Designed as a full-size seat, it offers the same level of comfort and support as the primary seat, allowing children to sit upright or recline to a near-flat position for napping. The seat features a multi-position recline mechanism, adjustable leg rest, and a five-point safety harness to ensure a secure and comfortable ride. Its compatibility with the City Select 2 frame is seamless, utilizing the existing mounting points for quick attachment without the need for additional adapters.

Constructed with a durable, weather-resistant fabric in the Radiant Slate color, this seat kit withstands everyday use and clean-up with a simple wipe. The padded seat insert provides ample cushioning for long walks or errands, while the canopy offers UV protection and a peek-a-boo window for monitoring the child. The seat can be positioned in multiple configurations—forward-facing, rear-facing, or facing the parent—allowing caregivers to customize the stroller layout based on preference and the ages of the children.

Weight capacity supports children from birth up to a substantial limit, though specific weight restrictions apply for the infant mode with the included liner. Installation does not require any tools; the seat clicks securely into place on the stroller frame and can be removed just as easily when converting back to a single stroller. The compact fold feature remains functional even with the second seat attached, enabling convenient storage and transport.

This compatibility ensures that families can expand their stroller system without sacrificing portability or storage space. Material quality includes a sturdy steel frame within the seat, combined with high-density foam padding that maintains its shape over time. The fabric is resistant to stains and fading, and the entire seat can be removed for spot cleaning.

The harness adjustors are smooth to operate, and the buckle is designed for one-hand release. As an accessory, it serves as a reliable solution for parents expecting another child or for caring for siblings close in age, providing a safe and comfortable riding experience without requiring a whole new stroller purchase. Its value lies in extending the functionality of the existing City Select 2 stroller, offering a cost-effective alternative to buying a separate double stroller.
