In this guide
Cybex and Maxi-Cosi are two of the best-known car seat brands in the UK, and they're the two NuaNest parents add to their lists most. Both make seats for every stage, from newborn carriers to high-back boosters, so the right choice usually comes down to the specific seat rather than the brand.
The quick answer
- Both make seats approved to R129 (i-Size), the current standard, and both offer ISOFIX bases and rotating seats.
- Compatibility is often the deciding factor: if you've already chosen a pushchair, check which brand's infant seat fits it with adaptors.
- Your car matters as much as the seat. Check the maker's vehicle fit list before you buy, especially for rotating seats and bases.
What to compare
Stage and size. Infant carriers suit roughly the first year; extended rear-facing seats keep your child facing backwards for longer, which safety experts recommend for as long as practical.
Rotation. A seat that swivels towards the door makes lifting a baby in and out much easier, at the cost of weight and price.
Base system. An ISOFIX base can stay in the car. Some bases fit more than one seat from the same brand, which can save money as your child grows.
Fit in your car. Measure the space, check the fit list, and if you can, try it in your own car before you commit.

Questions parents ask
Are Cybex and Maxi-Cosi seats equally safe?
Every seat sold in the UK must pass the same safety tests. Look for R129 (i-Size) approval, and the seat that fits your car and your child best is the safest choice.
Do Cybex car seats fit Maxi-Cosi bases?
Generally no: bases are made for their own brand's seats. Always check the base and seat are listed as compatible.
How long should my baby rear-face?
R129 seats require rear-facing until at least 15 months, and many experts recommend staying rear-facing for longer if the seat allows it.
