Quick answer
For most families with twins or close-in-age siblings, a side-by-side double pushchair offers equal comfort and easy conversation, while a tandem (front-to-back) model is better for navigating tight doorways and shop aisles.
Tandem vs side-by-side: key trade-offs
A tandem double pushchair has seats arranged one behind the other. This makes it narrower—typically fitting through standard doorways—but the rear child may have a restricted view and less legroom. A side-by-side stroller gives each child the same view and space, but is wider and can be harder to steer in crowded areas.
Consider your daily routes: if you often go through narrow shop entrances or public transport barriers, a tandem design is more practical. If you walk in parks or wide pavements, a side-by-side model offers a more equal experience for both children.
Weight and age of your children
Check the maximum weight per seat. Most double pushchairs support children up to 22 kg per seat, which covers from birth to around 4 years old. If you have a newborn and a toddler, look for models with lie-flat recline or a compatible carrycot option.
The Joie Estrella Double Pushchair and Cybex Gazelle S both offer lie-flat recline suitable from birth, so you can use them without a separate carrycot. The Nuna TRVL DUBL is side-by-side and also works from birth, but its compact fold makes it ideal for travel.
Decision rules for choosing a double pushchair
- Measure your doorways first: Standard door width is about 30 inches (76 cm). Most side-by-side strollers are 29–32 inches wide. Tandem models are usually 24–28 inches. Measure your home doors and any shop entrances you use daily before choosing a width. If your doors are narrower than 30 inches, choose a tandem model.
- Check weight limits and seat recline: Look at the maximum weight per seat and whether the seat reclines flat. For a newborn, you need a lie-flat recline or a compatible carrycot. For older toddlers, a seat that supports up to 22 kg is standard. If you have a baby under 6 months, ensure at least one seat offers a lie-flat position.
- Consider your storage space: Tandem pushchairs often fold larger than side-by-side models. Check the folded dimensions and whether the stroller stands when folded. Side-by-side strollers like the Nuna TRVL DUBL are designed for compact storage. If you have a small car boot, prioritise a model with a compact fold.
- Think about seating configuration flexibility: Some tandem models let you attach a second seat, a carrycot, or a car seat in different positions. The Cybex Gazelle S offers over 20 configurations, including lie-flat seats without a carrycot. Side-by-side models usually have fixed seats. If you need to switch between a newborn and toddler setup often, choose a modular tandem system.
