Safety 1st Ellaris
Safety notice: No US recall names the Ellaris (searched 19 Oct 2026). Check your seat's model number and date of manufacture at nhtsa.gov/recalls.
Pros
- About 12 lb, light enough to swap between cars or carry through an airport
- A 3-in-1: rear-facing to 40 lb, forward-facing to 65 lb
- Compact frame leaves legroom for the front seats
- Machine-washable, dryer-safe seat pad and dishwasher-safe cup holders
Cons
- Hook-style LATCH, so a tight install depends on how hard you pull
- The harness is rethreaded by hand
- Rear-facing stops at 40 lb rather than 50
- At 19 in wide it is not a three-across seat
Our Verdict: Safety 1st Ellaris
The Safety 1st Ellaris scored 81 out of 100 and took Best Lightweight Travel & Budget Choice in our convertible car seat guide. We score every convertible car seat on seven criteria. Six of them, crash test, ease of install (latch), ease of install (belt), ease of use, comfort & durability, and weight, are not scored for this one, so read this review as an incomplete picture until we have them.
Weight is its selling point: about 12 lb against 19.5 lb for the next lightest, so swapping cars or carrying it through an airport is realistic. It's a 3-in-1, rear-facing to 40 lb and forward-facing to 65 lb.
Hook-style LATCH means the tightness depends on how hard you pull, the harness rethreads by hand, and at 19 in wide it isn't a three-across seat.
