Designed with a slimmer profile, this seat, which supports children up to 100 pounds, is only 17.4 inches wide to fit comfortably into smaller cars without sacrificing any of the support, safety, and comfort a child requires. The 19.5-pound seat can be set up as a rear-facing, forward facing, and high-back booster seat to accommodate growing children. It also features a 10-position adjustable headrest and harness and an anti-rebound bar that provides additional safety during rear-facing rides as well as a well-coded, fat-buttoned belt system that makes installation simple.
