UPPAbaby RumbleSeat V2+ Review: The Second Seat Your Vista Needs?

When your family grows from one child to two, the stroller situation gets complicated fast. The UPPAbaby RumbleSeat V2+ promises to turn your Vista V2 or Vista V3 into a capable double stroller without buying an entirely new system. I spent several weeks testing this second seat attachment with two kids in tow, navigating grocery stores, parks, and crowded sidewalks.

The RumbleSeat V2+ slots into the lower position of the Vista frame, creating an inline double stroller configuration. At $149.99, it represents a significant add-on cost to an already premium stroller ecosystem. The big question for growing families: does it deliver enough value and comfort to justify the investment, or should you consider a standalone double stroller instead?

What I Liked About the UPPAbaby RumbleSeat V2+

Increased Weight Capacity to 40 lbs

The V2+ bumps the weight limit from 35 lbs on the older RumbleSeat to 40 lbs. That extra 5 lbs translates to several more months of use before your child outgrows the seat. For parents spacing their children 2-3 years apart, this upgrade makes a meaningful difference in how long the double stroller setup remains practical.

Five-Point No-Rethread Harness

The harness adjusts with a single pull motion, and you never need to rethread the straps as your child grows. This sounds like a small detail until you’re trying to buckle in a squirming toddler at the grocery store. The adjustment is smooth and locks securely at each position.

One-Handed Multi-Position Recline

The recline operates with one hand, which matters when your other hand is holding a child or pushing the stroller. The seat moves between forward-facing and parent-facing orientations, so younger children can face you while older ones look ahead. Multiple recline angles let your child nap comfortably during longer outings.

UPF 50+ Extendable Canopy

The canopy extends further than the previous version and includes a zip-out panel for full UPF 50+ sun coverage. A peekaboo window lets you check on your child without stopping. The height-adjustable design accommodates taller children as they grow, preventing that awkward gap between the top of their head and the canopy edge.

Adjustable Multi-Position Footrest

The multi-position footrest keeps dangling legs comfortable. It adjusts to match your child’s leg length, and the positions click firmly into place. This is a welcome feature that the older RumbleSeat lacked, and it noticeably reduces fidgeting on longer walks.

Quick and Easy Installation

Large hubs and included adapters make attaching the RumbleSeat V2+ to the Vista frame straightforward. The connection points are intuitive and click solidly when properly seated. A bumper bar and bug shield come included in the box, which saves you from buying them separately.

What Needs Improvement

Lower Position Only Limits Configurations

The RumbleSeat V2+ can only mount in the lower position on the Vista frame. If you want a bassinet or infant car seat on top with an older child below, the RumbleSeat is your only option. The regular toddler seat will not fit in the lower position. This effectively makes the RumbleSeat a mandatory purchase for most double stroller configurations, adding to an already expensive system.

Smaller Than the Main Toddler Seat

The seat is noticeably smaller than the main Vista toddler seat. The toddler seat supports up to 50 lbs and 40 inches, while the RumbleSeat V2+ maxes out at 40 lbs and 36 inches. Taller toddlers may hit the height limit well before they reach the weight limit, shortening the usable lifespan of the seat.

Added Bulk in Double Mode

Running the Vista as a double stroller with both seats loaded adds considerable weight and bulk. Navigating narrow store aisles and doorways requires more effort, and the longer wheelbase makes tight turns challenging. Parents who frequently navigate urban environments should factor this into their decision.

Younger Babies May Need Extra Support

Younger babies around 3-4 months old may lean to one side in the seat before they develop enough core strength to sit upright. An infant insert helps address this, but it is sold separately and represents yet another accessory purchase.

How the RumbleSeat V2+ Compares to Other Double Stroller Seats

vs Mockingbird Single-to-Double Second Seat

The Mockingbird Single-to-Double Stroller system costs around $450 total, compared to $1,000+ for a full Vista setup with the RumbleSeat. The Mockingbird second seat offers a similar inline configuration at a fraction of the price. Build quality and accessory ecosystem favor UPPAbaby, but the Mockingbird delivers strong value for families who do not need the Vista’s extensive compatibility with bassinets, car seats, and the PiggyBack board.

vs Nuna Demi Grow Sibling Seat

The Nuna Demi Grow takes a different approach with two identical-sized seats stacked vertically rather than the Vista’s different-sized inline arrangement. The Demi Grow includes dual adjustable suspension and an all-weather mesh seat, features the RumbleSeat V2+ lacks. Both strollers weigh roughly the same in double mode (around 12-13 kg). The Vista offers more total configurations and a broader accessory ecosystem, while the Nuna provides equal seat sizes for both children.

Final Verdict

The UPPAbaby RumbleSeat V2+ is a well-engineered second seat that makes the Vista a functional double stroller for growing families. The increased 40 lb weight capacity, one-handed recline, and UPF 50+ canopy deliver genuine improvements over the previous version.

I’m giving the UPPAbaby RumbleSeat V2+ a 4.3 out of 5. The comfortable harness, easy installation, and broad Vista compatibility earn high marks. Points come off for the smaller dimensions compared to the main toddler seat, the mandatory nature of the purchase for double configurations, and the added bulk when fully loaded.

Bottom line: if you already own a Vista V2 or V3 and are expecting a second child, the RumbleSeat V2+ is the most practical way to expand your stroller without starting over.
