  "title": "Single-to-Double Strollers That Add a Second Seat Later",
  "question": "Which single-to-double strollers can be converted to take a second child later?",
  "answer": "Bugaboo Kangaroo Seat Complete Stroller: It is a single-to-double stroller sold in a seat-only version so you can start with one child and adapt later. It converts to a tandem stroller by adding a Bugaboo sibling seat, which is sold separately. It is for toddlers from 6 months to about 4 years, with a maximum seat capacity of 50 lbs (22 kg).\nCybex Gazelle S 2: Converts from single to double without adapters. Integrated seat adapters tuck into the frame, and the top adapters shift up for a second seat or to bring the shopping basket close.\nBugaboo Kangaroo Complete Stroller + Bassinet Bundle: An all-terrain single-to-double stroller that can be used as a newborn stroller and expanded for two or three children. Seat holds up to 50 lbs / 22 kg.\nCybex Gazelle S: Owners highlight that no adapters are needed to switch to double mode and that the second seat matches the first seat's weight limit, unlike some rival rumble seats. Praised for offering around 20 configurations with built-in adapters, which makes switching between setups much easier for parents, and called a strong option for twins.\nBugaboo Donkey 6 Complete Single-to-Double Stroller + Essential Accessories Bundle: A reviewer who tested the conversion in store found it works exactly as claimed: three clips, press a button, slide to expand the frame by 14 cm, no tools and under a minute; the expanded frame felt solid with no flex or wobble. In double mode the stroller is 29.1 inches wide and the listing says it still fits through standard doorways.",
