My Buying Guide on ‘Graco Affix Highback Booster’
When I was searching for the perfect booster seat for my child, the Graco Affix Highback Booster caught my attention. Here’s what I learned and considered during my buying journey, which I hope will help you make an informed decision.
Why I Chose the Graco Affix Highback Booster
I wanted a booster seat that combined safety, comfort, and ease of use. The Graco Affix offers a highback design for extra head and neck support, which was important for me as my child still needed that protection during longer rides. It also easily converts to a backless booster, giving it extended usability as my child grows.
Key Features That Stood Out to Me
- Highback and Backless Modes: I appreciated how versatile the seat is, allowing me to switch between modes depending on my child’s needs and the car’s seating arrangement.

- Adjustable Headrest: The multiple height positions helped me customize the fit as my child grew.
- Comfortable Padding: The seat has ample cushioning which kept my child comfortable on both short trips and longer drives.
- Easy to Clean: The fabric cover is removable and machine washable, which is a big plus for busy parents like me.
Safety Considerations I Looked For
Safety was my top priority. The Graco Affix meets or exceeds all U.S. safety standards and has side-impact protection, which reassured me. I also checked that it was easy to install correctly since improper installation can reduce safety. The seat’s secure fit in my vehicle was a big factor in my decision.
What I Considered About Size and Fit
Before purchasing, I measured the back seat of my car to ensure the booster would fit comfortably without crowding other passengers. The Affix’s slim profile was ideal for my sedan, and the adjustable features meant it could accommodate my child’s growth from about 40 to 100 pounds.
Pros and Cons Based on My Experience
