Facts from the maker or a manual quote the page word for word; what real users report is summarised with a link to the page read. Recall status was checked directly with CPSC (United States), Health Canada: CPSC search returned no recall records for Uppababy/Alta V2. Health Canada's four Uppababy records concern RIDGE strollers, RumbleSeat adapters, bumper bars and a Peg Perego adapter, none for Alta V2. Official safety test results were looked up directly with CREP, the Child Restraint Evaluation Program, NHTSA's Car Seat Ease of Use Ratings, ADAC's child seat test: CREP, the Child Restraint Evaluation Program (Australia and New Zealand): CREP's published list of 216 seats has no UPPAbaby or Alta V2 entry, and the list is complete, so this seat has no CREP rating. NHTSA's Car Seat Ease of Use Ratings (United States): NHTSA lists an UPPAbaby Alta V2 Jake-style model 1320-ALT-US-JKE, made 2025-04-01, with 3/5 overall ease of use: vehicle installation 5/5, instructions 4/5, securing the child 2/5 and labels 2/5. The model number differs from the maker's 1302-ALT-CA-JKE, so check the label; these are ease-of-use ratings, not crash-test results. ADAC's child seat test (Germany, the UK and Europe): ADAC's published list includes only UPPAbaby Mesa i-Size entries, not the Alta V2; the list is complete for its published tests, so no ADAC grade applies to this booster. Not read, because they are member-only or refused RoboTrunk: Consumer Reports car seat ratings, Which? child car seat tests, JPMA certified products. Still open, with no evidence found: Are tools needed to assemble the booster?; Does it fit three child seats across a typical rear bench?; Does it fit a Toyota RAV4 rear seat without hanging over?; Will the fabric stain or pill with everyday use?; Is it certified to ECE R129 or i-Size?; How many recline positions does it actually have?; Does it work with inflatable seat belts?; Does it work with switchable seat-belt retractors?; Does the cup holder hold a large 32 oz bottle securely?; Does the seat have a top tether?; Are replacement covers or parts sold separately?; Does the cover shrink after machine washing?.","tier":"complex","depth":"trimmed_read","model":"deepseek-flash","recall":{"note":"CPSC search returned no recall records for Uppababy/Alta V2.
