Summary: This was a purchase for my vehicle to transport our oldest daughter to school in the mornings. The trip is only about 1 mile so I felt comfortable looking at a Booster seat. Our primary seats for our two girls are Recaro with 5-pt harness and Latch systems. These are the basis of my experience and several months of reading reviews etc prior to purchasing. I couldn't be happier or more comfortable with a primary seat purchase.
But, back to the Clek booster seat.
Summary: Quality is great and seat is comfy. My daughter loves her new seat and I really like that it locks to the car. The only con I have is that the booster sits too close to the seatbelt buckle, and hence is not too easy for my 5yr old to put on her seatbelt by herself. Is not super hard, yet is something to consider. i have a 2010 Mazda 5. Overall, I'm very happy with the purchase.
