Lifelong Cuppy 2-in-1 ISOFIX Car Seat
From 9 kg, up to 36 kg (~9 months to 12 years).

Pros / Cons
Pros
- ISOFIX connectors and a five-point harness cover the 9-18 kg stage, while the same shell converts for later vehicle-belt use through 36 kg.
- An adjustable headrest, removable washable cushion and cup holder make the long harness-to-booster span easier to manage.
Cons
- The manual provides no rear-facing mode and starts forward-facing use at 9 kg, so families wanting a longer rear-facing stage need a different seat.
- The restraint setup changes with weight and the internal harness is removed for later stages, so belt routing must be reset exactly as the manual shows.

Lifelong Cuppy LLCCS021 suits families who need a forward-facing seat from the 9-18 kg harness stage through later booster use and have a compatible vehicle position. Its clearest advantage is the documented progression: 9-18 kg, 15-25 kg, and 22-36 kg configurations, with ISOFIX installation and an adjustable headrest. The overlapping bands are not an automatic timetable for moving a child onward.
Before buying, check the LLCCS021 instructions against the child and car. This is not a birth seat and the reviewed material does not support rear-facing use. At every change, use the restraint, belt route, headrest position, and installation method specified for the current configuration; do not remove the harness or switch to vehicle-belt booster use from weight alone. Also confirm that the shoulder belt sits correctly in booster mode and avoid accessories or routing not approved in the supplied instructions.
