  "answer": "Britax S864900: It should not be used as an infant insert and should not be used for children over 22 lbs. Strolleria's listing says the pillow is crash tested and approved for Britax convertible and infant car seats for children up to 22 lbs; sources disagree on compatibility, as the video reviewer says it is stroller-specific and cannot be used across all Britax car seats. Forum members asked whether the pillow had actually been crash tested and whether it is approved for all Britax seats or only some, and quoted Britax's approval wording for convertible and infant car seats.\nChicco Fit360 Mirror Car Seat Accessory: It is a shatter-resistant rear-facing mirror specifically designed for the Fit360 Rotating Convertible Car Seat and gives a targeted view of the child without adjustment. Unlike aftermarket mirrors, this accessory is made, tested and approved by the car seat manufacturer rather than being a third-party add-on.\nClek Mat-Thingy: Designed for use with all Clek car seats and booster seats. Sources disagree on dimensions: Bambi Baby lists 18.75\" L × 18.5\" W, while Little Canadian lists 25\" L × 19\" W × 1\" H.",
