Type: Convertible seat, booster.
Limits: 5-40 lbs. rear-facing, 20-65 lbs. in harness mode forward facing and 30-100 lbs. as a belt-positioning booster
NHTSA ease of use rating:
Rear-facing: Three out of five stars.
Forward-facing: Four out of five stars.
Booster mode: Five out of five stars.
IIHS rating for booster mode: Best bet.
Pros: All in one seat works from 5 lbs. through booster mode. Affordable. No rethread harness.
Cons: Doesn’t work as a backless booster, as sister model 4Ever does. Only one cup holder. Some downgrades versus Graco 4Ever.
Key features of the Milestone include EPS foam lined seat, side impact protection headwings, four position recline and an adjustable headrest. The seat pad is removable and machine washable. We liked the no rethread harness, which is impressive at this price level.
The Milestone was released back in 2014 and reader feedback has been quite positive. Fans like the seat’s overall comfort and value—at $200, the extended use of the seat (from convertible to high back booster) wins many fans.
So what’s the difference between the Milestone and Graco’s other new all-in-one seat, the 4Ever? The big difference is the booster mode: the 4Ever converts to a backless booster to 120 lbs. The Milestone has no backless mode and stops at 100 lbs. Then there are minor differences: recline positions (Milestone’s four vs the 4Ever’s six) cup holders (one on on the Milestone that hangs off the side of the seat, versus two integrated cup holders on the 4Ever). The 4Ever works better for preemies (the 4Ever starts at 4 lbs; the Milestone at 5 lbs.). There’s no level indicator on the Milestone to aid rear-facing installation.
When the Milestone and 4Ever were launched, there was a $70+ price difference between the two. As of this writing, that has narrowed to $57. Given the numerous upgrades with the 4Ever, it is probably worth the extra the bucks.
In their most recent ranking of all-one-seats, Consumer Reports gave the Milestone and 4Ever top marks over competing seats like the Evenflo Symphony. And we would agree with that sentiment, given our own reader feedback.
We’ll give the Milestone the same rating as the 4Ever as they are essentially the same seat—but the Graco 4Ever is the better buy. Rating: A-
