How we researched this

2 current models compared
Specs from each manufacturer’s page or manual
NHTSA and CPSC recall records searched
5 official sources cited

What we looked for

Rear-facing weight and height limits, since NHTSA and the AAP advise rear-facing until your child reaches the seat's limit
How each seat installs and how easily you load a child
Width and weight, for small cars and moving between vehicles
Recall history and useful life

Research-based: limits and dimensions from each manufacturer's manual or spec page, recall history from NHTSA and CPSC data, and list prices from the manufacturers' own sites in October 2026. We have not crash-tested or installed these seats. Both must meet the same federal standard, FMVSS 213.

The short answer

Choose the Britax Poplar if you want the easiest tight install with a seat belt and the most rear-facing height. Choose the Evenflo Revolve360 Slim if lifting a toddler into a rear-facing seat is the hard part: it swivels toward the door, and its base stays put. Both rear-face to 50 lb and fit in about 17 in of width.

Where they really differ

Installing it. The Poplar uses Britax ClickTight: you open a panel, buckle the car’s seat belt through, and close the panel to clamp it tight. You don’t have to pull the belt tight yourself. The Revolve360 Slim installs a base once, using a built-in belt tensioner or the lower anchors, and the seat stays on that base whichever way it faces. On both, the lower anchors are only rated up to a 35 lb child; after that you switch to the seat belt.

Getting your child in. This is the Revolve360 Slim’s reason to exist. The seat swivels toward the open door, so you can buckle a heavy rear-facing toddler without lifting them over the side of the shell. With the Poplar, you lift and lean in like any fixed seat.

Rear-facing room. Both rear-face to 50 lb. The Poplar allows 1 in more height (49 in against 48 in). The Revolve360 Slim starts at 4 lb instead of 5 lb, which matters only for very small newborns.

Moving it between cars. Both weigh about the same, 27.2 lb for the Poplar and 28.2 lb for the Revolve360 Slim with its base. Neither is a seat to move daily; the Revolve360 Slim’s base makes it a little more of a commitment.

Recall history. We found no recall naming the Poplar. Revolve360 Slim seats made from December 1, 2022 to December 8, 2024 are covered by NHTSA recall 25C010000: a child could pick off headrest foam. Evenflo sends a free fix. Check the manufacture date on the seat’s label and order the fix if yours falls in that window.

Price. On the makers’ own sites in October 2026, the Revolve360 Slim listed for about $50 more than the Poplar. You’re paying for the rotation.

Frequently asked questions

Is one of these seats safer?

Not in a way you can buy. Every seat sold in the US must meet the same federal standard, and the AAP says no single seat is the safest: the best seat fits your child, fits your car, and is installed and used correctly every time.

How long should my child stay rear-facing in either seat?

Until they reach the seat’s top rear-facing height or weight limit, as NHTSA advises. Our guide to rear-facing explains why.

What about other options?

Our convertible car seat guide also covers a budget seat for a second car and the narrowest seat we found for three-across.
