If you’re searching for the perfect single stroller, look no further. StrollAir’s CosmoS is the best full size single stroller designed with safety, comfort, convenience, and style — all with our experience and parent suggestions in mind.

CosmoS is an all-terrain, full-featured single stroller thoughtfully engineered with loads of features parents love. Newborns can lie flat in the comfortable CosmoS bassinette, which includes a mattress with a zippered cover that is easy to remove and wash. Once your baby is older, interact with your little one by reversing the seat to face you. When he or she is ready to explore, turn the seat forward so your baby can peer out at the world ahead. Additionally, our unique seat has an independently adjustable backrest and footrest, so older babies can nap comfortably with their legs outstretched. The CosmoS flat recline also allows for on-the-go diaper changes in the stroller.

Best in the industry, our extendable hood provides extra protection from the sun, wind, and inclement weather. The unique mesh vent in both the bassinette and seat hood allows for an extra breeze on a hot day, helping your little one sleep in comfort. A magnetic peekaboo window lets you to quietly check on your little one at any time. Our mosquito net keeps out those pesky insects, and the rain cover shields the baby if you get caught outdoors in the rain.

The optional Infant Car Seat Adapter fits most car seats on the market, allowing you to take your baby from car to stroller without disturbing your sleepy little one. You can accessorize your stroller with optional Air Tires, Universal Organizer / Cup Holder, and Front Bar Organizer / Snack Tray. You can even replace the seat with Shopping Tote when your baby no longer wants to sit and you need additional cargo space.

Transforming from travel system to bassinet to toddler stroller, CosmoS is the clear choice for your active lifestyle.

    Purchased one last year and been happy with it ever since. Bassinet is a must for newborn babies as they need to sleep on flat surfaces rather than in a car seat. Spent last summer by the pool with my son sleeping tight in bassinet, then switched to regular seat. It is lightweight and compact indeed, it fits in my Ford Fiesta’s small trunk, if seat and the base! The toddler seat is a blast, especially the hood with sun protection extension and mesh to let the air in while your baby is asleep. Watch their video review on YouTube, it really shows all the advantages of Cosmos stroller. Good deal for the price, well built, great looking. I’m getting compliments on it all the time!

    Tried out a lot of strollers. The Cosmos is the best by far and that’s comparing it to ones that cost $1,200 plus. Easy to use, lightweight and super sturdy! Love it!

    Its a pretty awesome stroller. I’m very happy with it so far. Comes with everything you need. Nice to have the bassinet for lying flat since that is most important for newborns. My only wish is that it had softer wheels for better suspension on rough, segmented sidewalks. My 4 month old is 27 inches so I hope she sits up soon since the bassinet fits up to 30 inches long.

    We recently bought a CosmosS single stroll air stroller for our daughter who is expecting her first child. We absolutely love the features of this stroller and its lightweight design. We had previously bought a twin stroll air stroller for our oldest daughter about three years ago. Our oldest daughter loves her twin stroller.

    We would highly recommend to anyone that is looking for a stroller to buy from stroll air. They won’t be disappointed. The owners of stroller air are great people as well.

    Excellent stroller: I searched for a stroller with a bassinet, with a toddler seat that reclines to 180 degrees, that fits well in Honda Civic trunk, and protects well from the sun and wind and can be used in Canadian winters. This stroller meets almost all these requirements (toddler seat reclines to about 160 degrees). The bassinet and toddler seat are both roomy and protect well from wind, easy to switch the seats, easy to navigate and remove wheels for cleaning with one click. It has front wheels lock system for easier navigation through snow. It makes the stroller harder to push when turning but at least it doesn’t get stuck in the snow.

    It doesn’t have a cupholder but I bought one for $5 and solved the problem. I have used it every day and already have offers from the neighbours to buy it when I dont need it.

    I can honestly say, that I’m so disappointed that there are not too many stores that carry this stroller in stock. I was hesitant to order, but you can’t beat the price with the amount of stuff it comes with. I could not be happier. I’m so excited to have the nicest stroller around and so comfortable for my baby. It has everything I wanted in a stroller and more. The quality is outstanding and it is so beautiful. This seriously is the best single stroller out there.

    This stroller is so beautiful and so well made. Black color is so nice. A bit shiny, so it’s easy to wipe. Basinette is a must. So nice and comfy for the baby. I truly recommend this product. It comes with everything. All you may need is a car seat adapter.

    Love it

    Love this stroller! Searched and researched a lot and this was by far the best. Easy to put together and its a large stroller so lots of room for baby and storage. One Con – Doesn’t fold very small.

    but it all fits together nicely and the quality is very good

    The baby hasn’t actually arrived so it hasn’t been used, but it all fits together nicely and the quality is very good. The wheels turn well and very smooth.

    Absolutely love this stroller.

    Easy to stow in the car and carry.

    Comes with everything you’d ever want in a stroller. It’s also light weight, comes with rain cover, mosquito net, basinette, hood that extends and also a diaper bag.

    It’s Canadian company made as well!

    Looking forward to this summer so I can take my son out for a stroll in this stroller.

    Amazon has really good price for this particular colour, I think it was about 150 dollors cheaper than other sites.

    Best stroller ever, and it’s a Canadian company!

    We have been in love with our stroller for the past 15 months. No problems with it other than the front wheels needing some WD-40 once in a while or with the handlebar clicking down when the basket is too full.

    We live in the city and don’t have a car so this stroller has been used A LOT, from the bassinet stages to now for a toddler. We take the bus often and it’s not too big and incommoding.

    We didn’t get too much snow last winter but when we did it was okay to navigate. We didn’t buy the air tires that are available but are considering it, as well as the toddler ride-along. We have the universal adapter that works with the 2 car seats that we own.

    For the price, it comes fully equipped (bassinet, diaper bag, rain/wind cover, mosquito net, foot muffs) and is good quality.

    The huge canopy is great, especially because we can also unzip the back for more air circulation.

    The best stroller ever. The price is great, amazing quality and all the accessories are included.

    It’s an amazing stroller. We couldn’t be happier. It’s super light, takes 2 seconds to put in the car, very well designed. Protects from the rain, the sun, the snow. My little guy is 2 months old so i’m using the bassinet and i love that he can be moving and sleeping on his back. I also love that i can use it as a change table when i’m out and about (an idea to make the stroller even better, would be to be able to drop the handle to be more comfortable with changing the little ones in it because it’s a little bit in my way. I know it’s not the main purpose but it’s so handy for changing and is a great advertisement plus for this stroller 🙂 ) Would not go with any other stroller.

    • Dear Celia,
      Thank you so much for your review. We are so happy that you love it!
      Enjoy your walks with your little one! 🙂

    I’ve had the StrollAir My Duo for a few years and have wanted a single stroller like it! I was so happy to find this. I love it! It’s just as great as our double. I believe strollair makes top of the line strollers!

    This stroller is absolutely perfect. I use the bassinet most of the time. Assembling the stroller was easy peasy, except for the bassinet piece because the instructions for this piece are really terrible.

    Here’s a tip:
    1. Place the bassinet on a tabletop on is short end.
    2. Inside the bassinet are two metal “handles”, one on each side.
    3. On each handle there is a small nylon loop. This loop is a finger pull.
    4. Make sure you move the loop so that it’s placed at the center of the top of the “handle”.
    5. Hold the bassinet firm and use the finger pull to pull one handle UP and toward you until it snaps in place. This could take some wiggling to get it fully snapped in. Do the same to the other side. Done. Now your bassinet is ready for action.
    The stroller moves easily and comfortably on gravel and cobblestones. It’s simple to take down to place inside the backseat of my car. This stroller is expensive, but it’s some of the best money I’ve spent.

    I have a StrollAir for my son and love it. I used it from birth until now- he’s 3 years old! It transformed to meet his needs as he grew. From bassinet when he was a newborn to stroller seat that I still use this stroller evolved. Plus, I was able to purchase an adapter for his infant carseat and attach it to the stroller frame for easy transport. The accessories were great too! I love the rain cover, diaper bag and the footmuff made it easy to keep him dry and warm as the seasons changed as well as carry his diapers and supplies. This stroller is awesome!

    The only things I’d add are cup/ bottle holders for parent and child.

    I just got the CosmoS, I am in the US and ordered on their website. It shipped really fast. It is an amazing stroller, I have never seen anything so well built, with high quality materials. With all the accessories and features, they really thought of everything. I also love the bassinet it comes with. I highly recommend this brand to anyone looking for a high end stroller for a reasonable price. I could not be happier :).

    We did a lot of research before buying our StrollAir, but we cannot be more happy with the purchase. The stroller has been through snow, sand, water and grass; it went on paved and unpaved roads, and after almost 2 years of using it for our grandson it’s still like new. This is one very well made product! I am not one to write reviews, but this stroller, including all the great accessories, is sooooo good that i had to let everyone know about it.

    Mesh Vent in Hood

    Babies love looking out the mesh vent. Being reclined helps them fall asleep and having a nice breeze on a hot day allows for a longer, more comfortable sleep.

  • product

    Large Extendable Hood

    In order to protect the baby from harmful sunrays, we have added an extension on the hood.

  • product

    Includes Bassinette

    The most comfortable way for baby to travel is in the bassinette.

    Included Foot Cover
