Overview
Evenflo's CS700212434 is a belt-positioning booster built for toddlers, with a listed weight capacity up to 120 pounds. It secures with the vehicle's own seat belt rather than a LATCH system, in a polyester cover over polyurethane foam padding.
The model number reads like an internal SKU rather than a marketed name, so shoppers searching by name may not recognize it. At just over 7 pounds it moves between cars more easily than a heavier convertible seat, and because it relies on the vehicle's own seat belt, fit will vary with your car's belt geometry.
- Belt-positioning booster orientation
- 120 lb weight capacity
- 7.1 lb item weight
- Polyester cover over foam padding
Who it's for
Suited to parents of a toddler who has outgrown a rear-facing infant seat and is moving into a belt-positioning booster, up to the 120 pound limit. Not a fit for infants or for anyone who wants a LATCH-installed harnessed seat.
Strengths and trade-offs
Drawn from this product's published specifications.
- Light at about 7.1 pounds for moving between vehicles
- High 120 pound weight capacity extends its usable years
- Works with any seat belt equipped vehicle seat
- Relies on seat belt fit, so comfort and security vary by vehicle
- No headrest or side impact details are given in the spec sheet
Performance notes
As a booster rather than a harnessed seat, the child is held by the vehicle's own lap and shoulder belt, with the booster raising and positioning them so the belt sits correctly across the hips and shoulder. Fit depends heavily on your vehicle's belt length and buckle placement.
