Bugaboo Donkey 6 Duo 3-in-1 Set incl. Bugaboo Otter by Nuna – The premium sibling travel system designed to grow with your family
Family life rarely stays the same. One child becomes two. A newborn arrives while a toddler still wants to explore the world. These transitions require more than just a stroller — they require a mobility system that adapts, protects and supports you every single day.
The Bugaboo Donkey 6 Duo 3-in-1 Set incl. Bugaboo Otter by Nuna is exactly that system. It is engineered for families with a baby and an older sibling, combining side-by-side connection with advanced car seat safety and long-term flexibility.
At Kindermaxx, we guide families through these decisions every day. What we have learned: investing in a modular, high-quality system from the start prevents compromises later. The Donkey 6 Duo with the Otter infant car seat is not a temporary solution — it is a long-term mobility strategy.
Understanding the Duo configuration – what makes it different?
The Duo version is ideal when you have a newborn and a toddler. One side accommodates the carrycot or infant car seat, while the other holds a full-size seat for your older child. Both sit next to each other at equal height.
This layout offers distinct advantages:
- Both children are equally visible and connected
- Better interaction between siblings
- Balanced weight distribution for smoother steering
- Clear view and access for you as a parent
The patented expandable frame allows you to switch from Mono to Duo in just three clicks. If you only need the Mono setup for a while, you can convert it back just as easily.
Real-world performance: manoeuvrability without compromise
Optimised width for daily life
In Duo configuration, the Donkey 6 measures approximately 74 cm in width. While this provides generous space for two children, it remains narrow enough to pass through standard doorways, supermarket aisles and most elevators.
Its intelligent weight distribution ensures:
- Stable steering even with two children
- Easy one-hand manoeuvring
- No dragging or imbalance feeling
- Confident control in tight spaces
Designed for every terrain
The extra-large, puncture-proof wheels combined with upgraded suspension allow you to glide over:
- City pavements
- Cobblestone streets
- Gravel paths
- Forest trails
- Snow and sand (two-wheel position)
This is particularly important for families who do not want their mobility limited by terrain.
Bugaboo Otter by Nuna – redefining infant car seat safety
The infant car seat is the most safety-critical element of any travel system. The Bugaboo Otter by Nuna has been developed in collaboration with Nuna, a globally recognised safety expert.
Advanced impact protection
The Otter integrates energy-absorbing foam designed to reduce impact forces in the event of a collision. The patented Tailor Tech™ memory foam headrest adapts individually to your baby's head shape, offering enhanced protection for the delicate head and neck area.
The reinforced carry handle contributes structural stability and helps manage rotational forces during impact.
10-position adjustable headrest
The headrest adjusts easily without rethreading the harness. This ensures that safety settings grow seamlessly with your child.
Three recline positions – including an ergonomic lie-flat angle
One of the Otter’s most valuable features is its near lie-flat recline position. This promotes a healthier posture for newborns and allows more comfortable sleeping during longer journeys.
When attached to the stroller frame, this recline feature becomes even more relevant for maintaining ergonomic alignment outside the car.
Optional: Bugaboo 360 ISOFIX Base by Nuna
For maximum ease of use, the Otter can be paired with the Bugaboo 360 ISOFIX Base (available separately). The 360° rotation function allows you to turn the car seat towards the door, significantly reducing strain on your back during daily use.
Without the base, the Otter can also be installed securely using the vehicle’s 3-point belt thanks to integrated belt guides.
Premium comfort for both children
While safety is paramount, comfort ensures peaceful journeys.
- Removable newborn insert for optimal support
- Breathable premium fabrics
- UPF 50+ extendable sun canopy with ventilation window
- Machine-washable covers (30°C)
The Otter feels luxurious while remaining practical for daily family life.
Sustainability built into the Donkey 6
The Donkey 6 has been redesigned with a 17% lower CO₂ footprint compared to its predecessor. Recycled aluminium, water-saving dye techniques and durable textiles reduce environmental impact without sacrificing durability.
Its modular expandability also prevents unnecessary future purchases — one system grows with your family instead of being replaced.
