The new Nuna Demi Grow is joining the great lineup of convertible strollers that go from single to double to accommodate a growing family. Currently the most popular convertible on the market is the UPPAbaby Vista stroller. How does the Vista compare to the new Demi stroller? The difference that stands out the most is the configuration when the strollers are in double mode. A second seat is added to the Vista in the lower position, in front of the main seat, while a second seat is added UNDER the main child on the Demi Grow stroller. This means less visibilty for the child in the second seat on the Demi grow and less leg room for them. The Demi includes fenders for the back wheels when you are using the second seat so as to protect them from flying dirt. Both strollers can accommodate two seats, two car seats and two bassinets at the same time. There is definitely more room on the Vista for each child, while the Demi Grow is much more compact. The Vista offers more configuration options. The Demi Grow can accommodate two children up to 50 lbs each, while the Vista can hold 50 lbs in the main seat and just 35 in the second seat. The UPPAbaby Vista includes the bassinet, while the bassinet is an extra accessory for the Demi Grow that needs to be purchased separately. The Demi Grow does include a dual footmuff and seat liner. The Vista includes a bug cover and bug cover for the bassinet as well, which the Demi does not. The UPPAbaby Vista weighs 26.3 lbs, while the Demi Grow weighs in at 30.6 lbs. Let's compare the seats. The seat on the Demi Grow is much more breathable with the ability to remove the seat fabrics for those hotter days. The Vista offers 5 recline positions, while the Demi offers just 3. The canopies on both strollers are large, but the one on the Demi Grow is larger with the Dream Drape and provides better coverage. Both strollers have really large baskets that are easy to access. The Demi Grow's basket is actually removable and features an extra compartment to store your things safely. The handlebars are easily adjustable on the Vista and the Demi Grow. The leather handlebar and belly bar details on the Vista are genuine leather, while they are leatherette on the Demi Grow. We do not know pricing yet for the Demi Grow so we can't compare the pricing of the two strollers, but we will update once we know more!
