The UPPAbaby Rumble Seat V3 in James is the purpose-built second seat for the Vista V3, designed to grow alongside your family from 3 months to 40 lbs. Road-tested in our boutique and loved by families nationwide, it attaches directly to the Vista frame with large, intuitive hubs — no guesswork, no fumbling.
All-Weather Comfort, Every Season
At the heart of the Rumble Seat V3 is an All-Weather Comfort Seat with a reversible Seasonal Seat Liner — plush fleece for crisp mornings, breathable mesh when the temperature climbs. The extendable UPF 50+ canopy with a vented peekaboo window and grow-with-me height adjustment means your child stays shaded and comfortable as they grow.
Thoughtfully Engineered for Everyday Life
The quick-to-secure harness system features a magnetic buckle and no-rethread harness, so buckling in a wriggly toddler takes seconds, not minutes. A one-handed, multi-position recline accommodates both forward- and parent-facing configurations, while the adjustable footrest keeps pace with your child's growth.
Premium Materials & Certified Safety
Crafted with premium fabrics and full-grain REACH certified leather details, the Rumble Seat V3 carries GREENGUARD Gold Certification — meaning it meets some of the world's most rigorous chemical emissions standards. All fabric is removable and machine washable, because real life is messy.
UPPAbaby Vista V3 Compatibility
Compatible with all Vista models from 2015 onward, including the Vista V2 and Vista V3. Suitable from 3 months to 40 lbs or 36" in height (whichever comes first), and from birth when paired with the UPPAbaby SnugSeat accessory (sold separately). Explore our full range of UPPAbaby Accessories and Shop All Stroller Accessories to complete your setup.
