Is UPPAbaby RumbleSeat V3 Second Lower Seat Good?
I’ll say yes for many families. The UPPAbaby RumbleSeat V3 Second Lower Seat is a great add-on for parents who already own a Vista. It turns a single stroller into a duo setup. It fits low on the frame so a toddler can sit or recline. It works best if you want versatility and plan to use a bassinet or car seat on top.
I used the UPPAbaby RumbleSeat V3 Second Lower Seat on a rainy city day. I had my baby in the bassinet up top and my toddler low. The low seat kept my toddler cozy and close. Folding with the lower seat removed was quick. I loved that I could swap seats and keep the stroller compact for trips.
What Makes It Stand Out / Key Features
- Lower seat designed for Vista V2 and Vista V3 frames.
- All-weather seat fabric for wind and light rain.
- Magnetic buckle for easy one-hand use.
- Includes adapters for simple install and removal.
- Reclines and offers footrest for toddler comfort.
What I Like
- Makes my Vista stroller a true two-kid solution fast.
- Low profile keeps both kids close and balanced.
- Magnetic buckle saves time when kids wiggle.
- Fabric cleans up well after snacks and spills.
- Build feels solid and matches the Vista look.
What Could Be Better
- Not a full stroller—needs a Vista frame to work.

I used the UPPAbaby Minu Duo Side-by-Side Double Stroller on a crowded holiday trip. It slipped down subway steps and fit through narrow store aisles. Folding it solo was fast. The kids had room and an independent recline. I liked how little trunk space it used in the taxi.
