Model Number  /  Manufacture Date50011-US-01  /  Jun 1, 2018
Harness Type5-pt
Weight  /  Height5lb - 45lb / up to 44"
Evaluation of Labels 1 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. There are diagrams of the various methods of installation for this mode on the labels, but they are labeled with icons and it is not clear that these are installation modes to select from. There is no indication of how to fit the harness to the child for this mode of use on the labels. The labels do not explain how to use LATCH in detail.
Evaluation of Instructions 4 stars
The instruction manual was not attached to the car seat when the car seat was removed from its packaging. No complete illustration of a child in the CRS is shown next to height/weight information. Supplemental sizing information is missing from the instruction manual. The belt routing section does not give routing instructions for lap-only seat belts.
Securing the Child 2 stars
The seat was not set for the smallest occupant when removed from the packaging. 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. If using in this mode after using as a booster for an older child, the harness must be rethreaded back into the seat, which requires carefully following steps in the owner's manual.
Installation Features 4 stars
There is a line printed on the seat that must be leveled to ground. 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.
