The Valco Baby Ultra Duo S2 Stroller: The 2026 Ultimate Guide - Valco Baby USA

The Valco Baby Ultra Duo S2 Stroller: The 2026 Ultimate Guide

by VALCO BABY in Stroller guide

When it comes to strollers, I feel like I’ve tried them all. With two kids and tons of gear, I know what I want and need and won’t settle for less. I’m through with big, bulky models that feel like a semi to maneuver. And my back won’t allow me to lift anything that a bodybuilder would be proud to show off. When I heard that Valco Baby released a new stroller, I had to admit I got excited. I absolutely love my Slim Twin and use it everywhere. So when I saw the announcement about the new Ultra Duo S2, I knew it was right up my alley. After using it for a while, I feel qualified to write a pretty comprehensive review and guide, outlining all the best features. If you’re a parent on the go, I can confidently say you’re gonna love the Valco Baby Ultra Duo S2 stroller. Still don’t believe me? See for yourself why it’s a must-have for anyone looking for a lightweight and versatile stroller that checks all the boxes.

Easy Folding

The Ultra Duo S2 is based on the design of Valco Baby’s super popular Trend Duo stroller, but with one new (and very exciting) updated feature. It boasts two independent reversible seats that stay on while the stroller is folded. That means you don’t have to waste time taking your stroller apart when you have a crying baby and toddler screaming that they’ve dropped their chicken nugget (if you know, you know). One of the main reasons I was skeptical about getting a double stroller was because I hated how long it took my friends to load it in their cars. They had to take each of the seats off one at a time and when they finally got everything loaded, the trunk was full. The Ultra Duo S2 is truly revolutionary. You don’t have to mess around with facing both seats forward or trying to figure out how to break it down. Simply use the one-hand folding feature to quickly fold the stroller no matter which direction the seats are facing, and you’re good to go!

Flexibilty

What I love is that you can choose to make the seats either forward-facing, which is great for older kids who love to see the world, or parent-facing, perfect for keeping an eye on newborns and babies. Or if your kids are a little more spaced out in age, face one forward and one backward. You can also choose from numerous add-on options like a bassinet, car seat adapters, and more. There’s endless customization possibilities, making the Ultra Duo S2 a flexible option for all stages!

Car Seat Compatible

Speaking of customization, the Ultra Duo S2 lets you attach one or two infant car seats in seconds with the optional car seat adapter—handy whether you’ve just got one baby along for the ride or two little ones traveling together. It’s great for when your little one is sleeping and you don’t want to disturb them and for families with infants and toddlers. Of course, if you don’t want to use the car seat adapter for your newborn, Valco Baby gave you that option, too. An optional bassinet enclosure (coming soon) will let them stretch out during walks for deep, uninterrupted sleep.

Multiple Color Options

I love when a stroller brand offers different color options. The Ultra Duo S2 comes in black for a sleek, timeless look or Rachel (coming soon) for a more modern alternative. I genuinely don’t know which color I like more, they’re both eye-catching, sleek, and ultra luxe. Of course, the fabric is easy to clean and made to resist the normal wear and tear that is inevitable with kids. You don’t have to hold your breath when the summer heat melts an ice cream cone or a spring outing gets a little muddy. The fabric wipes clean in seconds and resists stains, keeping it looking beautiful for the long haul.

Compact Design

As I said earlier, there’s nothing that bugs me more than a stroller that doesn’t fit through doors and aisles. What’s the point in putting your kids in a stroller if you can’t take it anywhere? That’s where the Ultra Duo S2 shines. It has all the space you need for your kids to sit comfortably and to store all your gear without the bulk or weight. It comes in at a narrow 28 inches wide so it easily fits through a standard doorway and tight spaces. When folded, the Ultra Duo S2 only measures 27.5 in x 13 in x 31 in so it fits into most standard vehicles without any problem. And since it’s lightweight at just 30 lbs, you don’t have to break your back during loading!

Adjustability

Another exciting feature on the Ultra Duo S2 is its adjustability. Practically everything can be adjusted to fit your family perfectly. For the littlest members, adjustable footrests with a built-in cocoon ensure even newborns have somewhere comfortable and secure to rest. The 3 - stage extended canopy, complete with a magnetic peek-a-boo window, protects sensitive skin from harsh UV rays and keeps everyone cool while letting you check in on your kids without lifting the fabric. When it comes to your stroller, you know there’s no such thing as a one-size-fits-all. With the Ultra Duo S2, kids can enjoy a comfortable ride designed just for them, with room to grow up to 45 lbs per seat.

Compact Fold

There’s few things as annoying after a long day than fighting to fold your stroller. I love that the Ultra Duo S2 has a compact clean-fold system that makes breaking it down a breeze. The compact design folds with the fabric on the inside and stands upright, protecting the seats from germs and dirt. Say goodbye to folding struggles, now you can load and unload with ease!

Durability

Of course, when it comes to choosing the right stroller, you want something that’s durable enough to last for years. The Ultra Duo S2 may be small but it’s definitely mighty—Valco Baby doesn’t mess around when it comes to quality. Of all the strollers I’ve tried, nothing else comes close. To ensure a smooth ride, the Ultra Duo S2 now features Infinity wheels with built-in suspension that absorb shock and glide across almost any surface—an upgrade that makes an already smooth ride even smoother. Thought and care was put into every aspect of the stroller, from the high-quality, easy-to-clean fabric that offers UPF 50+ protection to the padded, vegan leather handlebars—you can truly see and feel the attention to detail that gives you the confidence to know the Ultra Duo S2 is built to last.

Comfort

Your kids deserve to ride in comfort, even with a compact stroller. A taller seat design ensures your little ones will fit comfortably for longer. The multi-position, one-hand, near-flat recline lets you adjust their sitting position quickly and easily. There’s ample padding and support to protect growing bodies and make this stroller something your kids will look forward to riding in. Plus, the ventilated seat back keeps them cool and comfortable, even on hot summer days. In fact, I’ve said more than once after a long outing that I wish I could switch places with my kiddos and enjoy the cozy seats. I don’t think that’s too much to ask for!

Safety

For Valco Baby, your children’s safety is the top concern. A stroller is only as good as its safety features, which is why they made sure the Ultra Duo S2 was safe and secure. Each seat boasts an upgraded 5-point harness with shoulder straps that are easy to adjust, keeping little ones comfortably in place. Plus, two removable belly bars—one for each seat—give extra peace of mind. One of my favorite safety features is the foot brake lever, which makes it easy to keep the wheels from moving even on uneven surfaces. You can trust your little ones will be secure in this impressive stroller.

Storage

As a mom, you know storage is a premium feature that all too many strollers overlook. Kids come with a lot of stuff, so you need a place to put everything where it won’t fall out. The Ultra Duo S2 has you covered with an extra large easy access basket, with plenty of room for a diaper bag, toys, and whatever else you could need. I was really surprised at how much could fit in this basket, it really seemed like I could put in everything I needed and then some. If you’re sick of having to carry your bags when you go shopping, or losing items because your current storage basket isn’t deep enough, you’ll fall in love with the storage on the Ultra Duo S2.

The New Valco Baby Slim Twin S2 Stroller: A Real Mom’s Review - Valco Baby USA

The New Valco Baby Slim Twin S2 Stroller: A Real Mom’s Review

When it comes to strollers, I’ve always been pretty picky. Let’s face it, they’re not cheap, so I have very high expectations. Over the years, after four kids and counting, I’ve tried a bunch of different brands, and the one that has always checked all the boxes is Valco Baby. You just can’t beat the quality and thoughtfulness that goes into their strollers. So when I heard Valco Baby recently updated its Slim Twin stroller, I knew I had to get my hands on it. Because my kiddos are fairly spread out in age, it can be a challenge finding a stroller that fits our needs. After using the new Slim Twin S2, I’m ready to give my full, honest review, and, spoiler alert, I absolutely love it! If you’re looking for a full-sized double stroller that’s compact enough to fit where you want but roomy enough to bring everything you need, the Slim Twin S2 is the one for you! Adjustability When it comes to meeting our family’s needs, one of the most important features for any stroller is adjustability. It needs to work with where we’re at now but also offer room to grow. The Slim Twin S2 doesn’t disappoint! To start, I love the optional bassinet (coming soon) for evening strolls or when I want my littlest one to stretch out. It’s a super nice and ultra luxe addition! You can also individually recline each seat so one kiddo can nap peacefully while the other stays engaged with the world around them. And it’s not a partial recline; you can put those babies down to near flat so they stay comfy and cozy. The footrests also move up and down with a cocoon-style support that keeps younger babies secure. Of course, sun protection is a non-negotiable, since young skin is super delicate and sensitive. The Slim Twin S2 features two extendable canopies with UPF 50+ and convenient peekaboo windows, so you can keep an eye on what your kiddos are doing at all times. There’s also a ventilated seat back on each seat, which is such a relief on hot days. It’s true customization for kids from newborn to around 45lbs, so you know this stroller will last! Safety This point should have probably been the first on the list, but I was just so excited about all of the adjustable features I wanted to tell you about those first. But safety is every parent’s main concern. I want to know that when I put my kids in their stroller, they’re safe and secure. The Slim Twin S2 goes above and beyond to put my mind at ease. Instead of a simple lap or shoulder belt, both seats have an upgraded 5-point harness with padded shoulder straps that are easy to adjust, keeping little ones in place and comfortable. It also includes two removable belly bars (which is a huge bonus I haven’t seen on other compact strollers). Another of the Slim Twin S2’s new upgrades is the locking mechanism, which is easier to use with one-foot step engagement. Once locked, you can trust your stroller will stay where you put it, which was a huge requirement for me. Compact and Lightweight Did I tell you that I’ve gone through A LOT of strollers over the years, because I have! After my second daughter was born, I knew I had to upgrade to a double stroller. Let me tell you, it was a nightmare. First, the one I chose was so wide it couldn’t fit anywhere. I hated going shopping because I would knock down every piece of clothing in the aisle. So I tried an inline version. It seemed like the perfect answer, right? Wrong! The dang thing was huge, took up all my trunk space, and took forever to take apart. What I love about the Slim Twin S2 is that, even though it’s a full-sized double stroller, it’s super compact. Since it’s only 26” wide, it fits through standard doors, aisles, and busy streets easily. It’s also perfect for travel since you don’t have to fight with extra bulk. And at just 27 lbs, I don’t feel like I’m lifting a boulder every time I pick it up. Plus, you can fold it with just one hand, and there’s a carry strap included. Not only did the Slim Twin S2 make shopping with multiple kids enjoyable again (who knew that was even possible!), but it saved my poor back in the process! Compatibility As a mom, I’ve learned a lot over the years when it comes to my kids’ gear, and one thing my stroller must be is compatible. Compatible with what, you may ask. The car seat, of course! Look, I’m a woman who loves options; some days I want to take my baby out of his car seat and let him ride in the stroller, but when he’s sleeping, no force could make me interrupt his nap to unbuckle him, lift him up, and rebuckle him into a different seat. Of course, Valco Baby thought of that when designing the Slim Twin S2. By simply snapping in the car seat adapter, your double stroller becomes car seat compatible. That’s right, you have the option to snap your baby’s infant car seat right onto the Slim Twin S2 for unmatched flexibility! I guess this feature could have also gone under adaptability since it lets you customize your stroller for infants and older kids, but it’s such a good one I thought it deserved its own section. Smooth Ride One thing I’ve noticed about Valco Baby is they don’t cut corners. Parents are going to be interested in features that make their strollers adaptable, safe, and convenient, but what about the components that slip under the radar? I’m referring, of course, to wheels. You may have never even thought about the type of wheels your stroller has, but just like your car’s tires, they make all the difference in the smoothness of the ride. Where others may just slap on a pair that rolls, the Slim Twin S2 boasts top-quality Infinity wheels, now with built-in suspension for good measure. And when I say we will never go back to anything else, I mean it. Even my husband, who’s an avid car guy, made a comment about how nicely the stroller moves. It seems to glide over pretty much any surface so my kids aren’t bouncing around. It’s a lifesaver when they fall asleep and makes this stroller feel so luxurious. Even the little touches, like the vegan leather handlebar, make it feel like a stroller that costs twice as much. Storage Do your kids come with a lot of stuff? Because mine sure do. Another top concern when choosing a stroller was having enough storage. Not only do I need to fit a diaper bag and snacks, but I want there to be enough room for shopping bags, my older kids’ backpacks, or anything else I may need. The Slim Twin S2 has a huge storage basket with plenty of room for everything we bring along. It came in very handy on our last flight since it freed up our hands and arms by holding more than one carry-on. If you need to bring it, the Slim Twin S2 can hold it with room to spare! Slim Twin S2 Specifications •            Overall Width - 26 inches •            Stroller Weight - 27 lbs •            Weight Capacity - ~45 lbs per seat •            Stroller Open - W - 26 in x H - 42 in x L - 30 in •            Stroller Folded (with wheels) - W - 26 in x H - 16 in x L - 30 in •            Seat - W - 11 in x H - 18 in x D - 10 in •            Footrest Length - 9 inches •            Handle Height - 42 inches •            Seat to Canopy - 22 inches •            Basket - W - 24 in x H - 9 in x L - 23 in •            Wheels - Infinity wheels + suspension •            Colors - Black, Rachel When it comes to choosing a stroller, I know how overwhelming it can be. You want to make the right choice for your family, but if you’re like me, with so many options, you may not know where to start. Take it from someone who’s been around the block a few times with different strollers: you just can’t beat anything from Valco Baby. When it comes to double strollers specifically, the Slim Twin S2 really is the best. Nothing is left to chance; every feature is designed thoughtfully to work for both parents and kids. After using it for a while, I can say with confidence it’s the ultimate stroller for growing families who need full-size comfort without the full-size footprint. If you’re looking for a stroller that lasts, is fun to use, and has everything you need to make your outings unforgettable, you need the Valco Baby SlimvTwin S2!

The Valco Baby Ultra S2 Rachel SE: The Comprehensive 2026 Guide - Valco Baby USA

The Valco Baby Ultra S2 Rachel SE: The Comprehensive 2026 Guide

If you’re searching for a full-sized single stroller that’s lightweight and stylish, look no further than the Ultra S2 Rachel SE by Valco Baby. This eye-catching stroller has it all: flexibility, durability, and beauty. When I first had my son, I wasn’t sure what I wanted in a stroller. There’s so many different options, it felt overwhelming. One day, I was talking to my friend, and she recommended Valco Baby. She’d used them with her first little one and was planning to upgrade to the new Ultra Duo S2 once her second child was born. I trust her opinion, so I took the chance, and let me tell you, I’m glad I did. I’m absolutely in love with the Ultra S2 Rachel; it has everything I want in a stroller and more. I decided to use my experience to write a review that will hopefully help other moms find the perfect stroller without wasting their time on ones that simply don’t stack up to what the Ultra S2 Rachel has to offer. If you value quality and aren’t willing to compromise, this is the stroller for you! Lightweight Design Whether you live in the city or suburbia, no one wants a stroller that requires a gym membership to lift. The Ultra S2 Rachel is surprisingly lightweight for a full-sized stroller, coming in at only 17 lbs and holding up to 45 lbs, so it grows with your child from newborn all the way to toddler. I don’t know how Valco Baby managed to create such a durable frame without the added bulk, but they did. I have no problem lifting it into my trunk by myself, and I can even carry it upstairs without pulling out my back. The lightweight design makes it perfect for pushing up hills with my chunky little guy and maneuvering along busy sidewalks. After my C-section, I wasn’t allowed to lift heavy objects, and even after I was cleared by my doctor, I was honestly scared to pick anything up. The Ultra S2 Rachel was a lifesaver, allowing me to maintain my independence and bring my baby with me without worrying about lifting a heavy stroller. Adjustability I love that the Ultra S2 Rachel has a reversible seat so I can place my son forward or rear facing. When he was first born, I kept him facing me so I could keep an eye on him and have more peace of mind. As he got older, he loved looking around, so I simply turned the seat forward, and he could watch the world around him. The seat is so lightweight, changing position is a breeze. When he’s tired or cranky, I’ll still turn him toward me, and I notice he calms down much faster. Just a little pro-tip to keep in mind! Along with the seat’s position, you can also adjust the shoulder straps so they fit securely, and the multi-position, near-flat reclining feature is great for naptime. It isn’t just the seat’s positioning that’s adjustable on the Ultra S2 Rachel. The footrest also moves to grow with your baby, with a built-in cocoon that keeps newborns snug and supported, and the triple-stage canopy extension, complete with a magnetic peek-a-boo window, provides superior sun protection from every angle while letting you check on your little one without lifting the fabric. Compact and Foldable While I wasn’t sure about everything I wanted in a stroller, I knew it had to be compact enough to fit in my trunk. The Ultra S2 Rachel didn’t disappoint. The one-hand folding feature makes it easy to break down the stroller quickly, no matter which direction the seat is facing. You’ll never have to fight with it to fold or unfold; it maneuvers smoothly every time. It’s ultra-compact, so I can still fit groceries, shopping bags, and more. The compact size is also great for apartments, hotel rooms, and traveling, so you can have the comfort of bringing your own stroller with you wherever you go. And at just 21.5 inches wide, it slides through standard doorways and narrow store aisles without a fight. Versatility The Ultra S2 Rachel is a highly versatile stroller, made to move easily whether you’re shopping or exploring the neighborhood. The front swivel wheels make maneuvering in tight spaces easy, which is a relief when you’re trying to fit through small aisles or crowded sidewalks. And it’s not just easy to steer—the Ultra S2 Rachel is one of the most versatile strollers on the market thanks to its numerous optional add-ons like a bassinet, car seat adapters, and much more. I loved the bassinet during the newborn stage, since we liked to go on walks during naptime. The car seat adapter will make your life so much easier, since it lets you quickly attach your baby’s car seat without disturbing them during the transfer. The Ultra S2 Rachel is the ultimate dual-duty stroller that will fit all of your needs. Storage Did you know that kids come with a ton of stuff? Okay, of course you did, but what you may not have known is that you can have a stroller with enough room to fit all of it. The Ultra S2 Rachel has ample storage thanks to an oversized, easy-access basket that lets you fit everything you need and then some. I have no trouble fitting my diaper bag, toys, water bottle, and shopping bags. Plus, the deep walls keep everything securely in place, so you don’t accidentally lose something important like a favorite stuffed animal or blanket. Safety There’s nothing more important than your child’s safety, and safety is exactly what Valco Baby is known for. The Ultra S2 Rachel boasts a secure, upgraded 5-point harness with shoulder straps that are easy to adjust, keeping your little one safely and comfortably in place. There’s also a removable belly bar for added protection, plus a ventilated seat back that keeps them cool and comfortable on warm days. The canopy has built-in UPF 50+ that protects your baby’s sensitive skin. One of the best features is the quick foot brake lever that lets you lock your stroller in place even when your hands are full. I don’t have to worry about my stroller rolling away; I simply step down on the brake and know it isn’t going anywhere. Beautiful Design The Ultra S2 Rachel proves that functionality can be beautiful. The scalloped edge on the canopy is one of the first things that caught my eye. It adds the perfect amount of whimsy and really makes the stroller stand out from the rest. I love the cream color and the fact that the fabric is super easy to clean. Even small details, like the vegan leather handlebar, feel premium in your hands. Everything about the Ultra S2 Rachel screams luxury, from the finishes to the design and materials. It’s simplistic, yet stunning—what else could you want in a stroller you use every day! Ultra S2 Rachel SE Specifications •            Overall Width - 21.5 inches •            Stroller Weight - 17 lbs •            Weight Capacity - ~45 lbs •            Stroller Open - W - 21.5 in x H - 41.5 in x L - 30 in •            Stroller Folded (with wheels) - W - 21.5 in x H - 15 in x L - 30 in •            Seat - W - 12 in x H - 19in x D - 9 in •            Footrest Length - 10.5 inches •            Handle Height - 41.5 inches •            Seat to Canopy - 20 inches •            Basket - W - 16 in x H - 10.5 in x L - 19 in •            Wheels - Standard EVA wheels •            Colors - Rachel SE Valco Baby really went above and beyond with the Ultra S2 Rachel SE.

Whether you’re traveling and need a full-sized stroller that’s still lightweight, going on a fun outing, or just doing everyday activities, you can’t go wrong with the Ultra S2 Rachel. My family loves it, and I know you will too!
