Love this booster! It's so durable I'm on kid two and it's held up perfectly! They attachable toy is awesome to keep little ones busy while you are cooking and preparing meals. It's adjustable height grows with your kids. Sturdiness Very sturdy, attaches to kitchen chair with two adjustable straps for a nice tight fit. Durability This chair is now on child number two and boy does it hold up! This booster looks like I just bought it, no scratches, stains, discolorations, nothing. Design Very nice design, it has three adjustable heights on it to grow with your child as well as an adjustable tray to grow out with your child. Safety As long as your child is strapped in and the chair is properly tightened on your kitchen chair the child is safe. Of course never leave a child unattended in a booster or any place for that matter. Ease of Cleaning Super easy to clean, food wipes right off the chair, tray and even the straps are really easy to get food stains off.
