Mountain Buggy Cosmopolitan Stroller Review


The Mountain Buggy Cosmopolitan is a luxury slick modern stroller that is designed for parents who live in a city. Its main feature is a reversible seat that allows your child to look at you or the world.

It also converts into a FLAT-BED for a newborn, so you don’t even need to buy a bassinet. It is a very compact stroller with an easy fold.

The all-wheel suspension and Aerotech tires, create amazing maneuverability and provide a smooth ride.

Although it’s not an all-terrain stroller, it can easily tackle playground mulch, grass in the park, or gravel. This stroller is full of great features like a large canopy, adjustable footrest, and a huge basket that can handle 22 lbs of stuff!

The Cosmopolitan weighs 26 lbs which is quite average for a full-size luxury stroller with a reversible seat. It can be used from birth and up to 44 lbs. Since the seat is removable, you can use it as a frame by taking the seat out and replacing it with a car seat.


It gets a perfect score of 5 out of 5 stars from me because it is almost perfect. The only thing that needs improvement is its non-adjustable handlebar. I also wish it was not as bulky and weighed a little less.

The Cosmopolitan retails for around $549. It doesn’t come with any accessories except for the bumper bar. I wish the cup holder was included. There is also no pram option, but I guess you don’t really need it since the seat converts into a flat-bed.

The canopy is really a good size. It has two large panels that are zipped together. Unzipping them will expose a middle panel that is made out of dark mesh. I like that this canopy goes way down to the bumper bar.

There is a large peekaboo window with a no-noisy velcro closure. The back of the canopy is attached to the seat so it does NOT convert into a so-called ‘floating canopy’.

I wish there was that option. Overall, I think it’s a great canopy that will shade your child any time of the day.



It is a non-adjustable handlebar located 40″ from the ground. I think the fact that it doesn’t adjust is the ONLY con of this stroller.



It is 13″ wide and 22″ from the bottom of the seat to the top of the canopy. The seat is one molded piece, so it keeps its ‘V’ shape when reclined. It has a one-hand recline that allows for the seat to go to almost a flat position.

The seat also is reversible, so your child can face you or the world. This seat can accommodate a child from birth and up to 44 lbs.


The unique thing about this stroller is that it can be turned into a flat-bed if you undo two buckles underneath the seat. I love this feature! It creates a bassinet-like environment for your baby. Great for a newborn.



The harness is padded with a tricky buckle. To unlock it you will need to push two buttons in the middle and squeeze the buckle from both sides.



It has a removable swing-away baby bumper bar. The bumper is covered with the same fabric as the stroller (instead of the foam cover).



When in toddler mode, the footrest can be adjusted to provide your child with a more flat surface. The footrest area is made out of durable rubberized material for easier cleaning.



The basket can fit two large diaper bags! It’s really huge. The weight capacity of the basket is 22 lbs making it great to go grocery shopping. Two steel bars underneath the basket provide plenty of support for a heavyweight.

It is also very accessible from every side. The stretchy elastic mesh makes it easy to get things from the sides. That basket gets 5 stars from me :)



The Cosmopolitan rolls on four Aerotech tires with 8″ front wheels and 12″ rear wheels. Aerotech tires are a combination of rubber and EVA foam meaning you will never get a flat.

The front wheels are 360-degree swivel wheels that could be locked straight if the terrain gets rough. To lock them, you just press a button located on top of each wheel. Easy!

The Cosmopolitan has an all-wheel roundhouse suspension across the entire frame that helps to absorb some of the bumps making the ride smoother. Although it is an urban stroller, it can tackle grass, mulch, and gravel without a problem.



It has a single flip-flop-friendly brake in the back that locks both rear wheels in place. We like that!



The fold is easy, but you will need to use both hands. After pushing two buttons on both sides of the frame and a large button on the handle, it folds down flat. The automatic lock keeps it in place. 

When folded, it can stand on its own or you can pull it behind you like a piece of luggage. The folded dimensions are 25.1″W x 37.4″L x 13.8″H. In real life, it looks less compact than on the company’s site. Take a look at my photo below vs the photo from their site.



-Non-adjustable handle bar. I do expect to have an adjustable handlebar in a luxury stroller.

-More storage. I wish there was a storage pocket in the back of the seat for small items like keys or sunglasses.

-Bulky. As with most reversible seat strollers, the fold is a little bulky.  I think because the frame of the seat doesn’t fold at all it’s also longer than some of the other strollers.

  1. Hi Katrin,

    I just can across the MB Cosmopolitan and it seems like a great stroller. Was wondering what your thoughts are between this and the Armadillo Flip/Flip XT? I am mostly looking for a stroller to run errands with or short walks, as I already have a jogging stroller.

    I like the Flip models, but am thinking that the no bumper bar option might be kind of a drag.

    Which would you choose and why?

  2. Hi Katrin,
    I just read your great reviews on both the MB Cosmopolitan and the Nuna Mixx. I live in NYC, and I am trying to decide between the two strollers…is there one that you would recommend over the other?
    Thank you for your help!

  3. Hi Lana. Both of them are great strollers and of course both of them have their own pluses and minuses. I really like that Cosmopolitan can convert into a bassinet without any additional purchases. At the same time the seat on Cosmopolitan is lower (22″ to the canopy) while on Mixx it is 25″. So if you have a taller child it’s better to get Mixx. Another thing I like about Mixx is that the seat can fully recline creating bed-like environment for you child to take a nap and stretch. This can be used even when your child is older. On Cosmopolitan the flat-bed feature works only for younger babies. Once your child is older, he will be always in the sitting position when you recline the seat.
