  "title": "Second seats for a double stroller setup",
  "question": "Which second seat works with an existing stroller so two children can ride?",
  "answer": "Match the seat to your stroller model first, since each seat below fits only the stroller named. BABY JOGGER City Select Second Seat Kit: The kit converts a City Select single stroller into a double stroller. The store says it is compatible only with Baby Jogger City Select strollers, not every Baby Jogger stroller. The second seat has a maximum child weight of 45 lb. Cybex Gazelle S 2nd Seat Unit: CYBEX lists this seat unit as compatible with the Gazelle S stroller. CYBEX says the seat unit is suitable from 3 months up to 50 lb, while the store says from 6 months, so the sources disagree; newborn use requires a separately sold cot or infant car seat. The seat-unit manual gives a maximum occupant weight of 22.7 kg (50 lb). Baby Jogger City Select 2 Second Seat Kit: The kit converts a city select 2 single stroller into a double stroller. The full-sized second seat holds a child up to 45 lb and has a 5-point harness. Bugaboo Kangaroo Sibling Seat: It is made for the Bugaboo Kangaroo stroller and adds a second seat for tandem use. The store recommends it from 6 months, with a maximum child weight of 40 lb (18 kg); it is not for newborns. Bugaboo Donkey 6 Sibling Seat: The sibling seat turns a Bugaboo Donkey 6 into a side-by-side double stroller for a second child. The store listing says the sibling seat is for children from 6 months up to 22 kg (50 lbs), while the Donkey 6 North American manual says the seat maximum is 23 kg (50 lbs); the sources disagree on the kilogram limit.",
