Ready to go with room to grow! The Britax Poplar S Convertible Car Seat takes the stress out of moving to the next car seat stage thanks to the patented ClickTight Installation and slim Spacesaver design. This car seat accommodates up to 50 pounds rear facing to help keep your child riding safely even longer and easily switches to a forward-facing car seat as your child grows. ClickTight Technology installation provides fully open seat belt paths that are clearly labelled and easy to access, and the automatic tensioner takes care of the tightening. Slim outside and spacious inside, the toddler car seat features 17" Spacesaver technology designed to fit 3-across* without compromising on trusted Britax safety and premium comfort.

For reference-- the highest harness slot for each car seat is as follows-- Boulevard 19.5" Poplar S 18" Extend2fit (2 in 1 and 3 in 1) 17.5" They all have a 49" height max and follow the 1" rule. Kids can outgrow the car seats by height and/or by torso height, which is why the 1" rule applies and straps have to be coming from the correct spot. (At or below with RF and at or above with FF).

The Graco has an extending headrest as well, and goes taller rear facing. I’ve never heard of a child outgrowing it by height rear facing. In fact, I’ve seen pictures of teens and small adults (all obviously over the weight limit) fitting in the tall Gracos with an inch over their head. If height is what you want, the Graco wins. The Poplar is shorter. The Poplar has 17” top harness height (the Boulevard ClickTight had 18.5”) and the Graco has 17.5”. They’re both compact. They’re both easy to install. The ClickTight is easiest, of course, but if you have ever installed a non ClickTight seat you can easily install the Extend2Fit.
Big-headed kids with 99% heads may find they have less than 1'' above their head before the Poplar is outgrown otherwise.
I prefer the material quality and features of the Britax but I have big doubts about its ability to fit taller children rear-facing.
The Poplar headrest is a bit shorter than the Graco, which has me asking a whole new question about head size/percentile.
