What reviewers say about the Britax Poplar S ClickTight Convertible Car Seat
Only one whitelisted tester, Wirecutter (NYT), hands-on reviewed this exact model, naming the Poplar S a runner-up and 'the easiest convertible seat to install (by far).' It praises the fast ClickTight seatbelt install and the washable, dryer-safe, flame-retardant-free fabric, but flags tight rear-facing legroom despite the 50-lb limit and a heavy 29.1-pound body. As a single-source verdict, there is no cross-outlet corroboration.
Tested by Wirecutter
Consistently praised
- Requires less effort to install than any other seat tested; ClickTight seatbelt lock-off removes slack automatically and 'the seat does not budge'
- Fabrics have no added flame-retardant chemicals and can be machine-washed AND put in the dryer (top pick's fabric must be line-dried)
- No-rethread harness plus a narrow 17-inch width, among the narrowest available and good for small vehicles
Commonly flagged
- Limited rear-facing legroom despite the 50-lb limit; weaker than the other picks for keeping a child rear-facing longer
- Heavy and bulky at about 27-29 lb (Poplar S measured 29.1 lb with anti-rebound bar)
- LATCH weight limit is only 35 lb, so Wirecutter advises the seatbelt/ClickTight install instead
Where reviewers disagree Single-source only (Wirecutter), so no cross-outlet comparison is possible. Wirecutter's own internal tension: it calls the ClickTight install the easiest available yet ranks the Poplar S below the Graco Extend2Fit specifically because the Poplar is less suited to keeping a child rear-facing longer.

the Poplar seat requires less effort to install than any other seat we tested
although both Poplar seats have a 50-pound rear-facing limit, in our experience they don’t provide much legroom in rear-facing mode
These seats are not the lightest.
