5 Alternatives to the CBX Solution XI-Fix Child Car Seat

The closest value alternative is the Graco Junior Maxi i-Size R129 Highback Booster in Midnight Fashion. Like the CBX, it’s for children from 100-150 cm, so it covers roughly the same age range and is a straightforward highback booster for everyday use. What’s better is the price: at £34.99 it’s much cheaper, while still matching the CBX’s 4.7★ rating. What’s worse is that it feels like a more basic option, so if you want a more premium-feeling seat or are specifically drawn to the CBX brand, the Graco may seem less refined. Choose this if you want the best budget-friendly replacement for school runs, grandparents’ cars, or a second seat.

The Pink Fashion version of the Graco Junior Maxi i-Size R129 is essentially the same seat with a different colour. It compares very closely to the CBX on size range and rating, but costs a bit more than the Midnight version at £40.00. What’s better is that it gives you the same value and safety-focused i-Size R129 positioning, plus a colour some children will prefer. What’s worse is that it offers no real functional upgrade over the cheaper Graco. Pick this if style matters and you still want a low-cost, 100-150 cm booster.

The Kinderkraft I-Spark i-Size is another strong alternative, and it sits between the Graco and the CBX in price. It’s lighter at 4.5 kg, uses a 3-point seat belt rather than ISOFIX, and includes side protection, which makes it appealing if you move the seat between cars often. What’s better is the lighter weight and lower price at £39.90, which is helpful for families with multiple vehicles. What’s worse is that it’s limited to 15-36 kg, so it doesn’t quite match the CBX’s wider 15-50 kg claim. Choose this if you want a practical, portable booster and don’t need the extra upper weight margin.

The Graco Turn2Me Group 0+/1 ISOFIX 360° is not a direct alternative in age range, but it’s worth considering if you’re actually shopping for a longer-lasting seat for a younger child. It covers from birth to around 4 years, with rearward-facing support for longer and 360° rotation for easier loading. What’s better than the CBX is convenience for toddlers, especially in tight UK parking spaces, and the ability to keep a child rear-facing for longer. What’s worse is that it’s much more expensive at £126.95 and not suitable for older children. Choose this instead if you’ve realised you need a seat for a younger child rather than a booster.

The Maxi-Cosi Pebble 360 i-Size is an even more specific newborn option, designed for 40-83 cm children up to around 15 months. It’s a premium infant seat with one-hand rotation, easy-in harness, and strong side-impact protection. Compared with the CBX, it’s far less versatile for older children, but much better if you need a proper baby seat for the first year of life. It’s also the priciest option here at £146.00. Choose this if your child is still in the baby-car-seat stage and you want a high-end, easy-to-use seat for daily UK driving.

If you’re replacing the CBX Solution XI-Fix specifically, the Graco Junior Maxi i-Size R129 is the best like-for-like value pick, while the Kinderkraft I-Spark is a good lightweight alternative. If you need a different stage entirely, the Graco Turn2Me or Maxi-Cosi Pebble 360 are better suited to younger children.
