Model Number  /  Manufacture Date50305-US-01  /  Jul 18, 2018
Harness Type5-pt
Weight  /  Height5lb - 50lb / up to 44"
Evaluation of Labels 2 stars
There is not a full picture of a child properly restrained in the child seat directly next to sizing information on the labeling. Supplemental sizing information is missing from the labels. No indication of correct harness height relative to the child is given on the labels. The labels do not explain how to use LATCH in detail.
Evaluation of Instructions 5 stars
Supplemental sizing information is given in short, simple text. No complete illustration of a child in the CRS is shown next to height/weight information. No step-by-step installation instructions are provided for lap-only seat belt installation.
Securing the Child 2 stars
The user must attach the rear-facing base (included separately) prior to use in this mode. The harness must be rethreaded to adjust for the child's growth as well as for reassembly after cleaning. Loose parts may be generated when disassembling for cleaning. When converting to rear-facing mode, the LATCH belt must be rerouted through the belt path.
Installation Features 1 stars
It may be uncomfortable for those with larger hands to route the seat belt or LATCH belt through the belt path. Interference may be possible between the seat belt/LATCH belt and a harness component. There are fewer than three levels of recline for this mode of use. The LATCH attachments have buttons to depress for removal from the vehicle's LATCH anchors. The storage system for the LATCH attachments is labeled with a latchplate icon which users may find confusing.
