Babystyle Oyster4 Tandem Adaptors

Engineered specifically for the Oyster4 chassis, the Tandem Adaptors allow your pushchair to convert effortlessly from single to double mode. Whether you’re preparing for twins or accommodating close-in-age siblings, these adaptors provide maximum versatility and secure attachment for a variety of Oyster-approved components.

Designed to support multiple combinations, the adaptors are compatible with the Oyster4 Carrycot, Oyster4 Seat Unit, Oyster4 Tandem Seat, and Oyster Capsule Infant Car Seat (when used with the Multi Car Seat Adaptors). Wheel guards are included and must be used whenever a seat is positioned in the lower configuration for added safety.

The system also supports the Oyster Basket, offering additional storage or pet accommodation up to 9kg for everyday flexibility.
