Our test covers boosters and harnesses that attach to a dining chair, clip-on seats that attach to a table, and floor seats for young babies. Our review will tell you which seats and harnesses are:

• safest for your baby
• easy to use (for newly tested models)
• have the features to suit your needs.

Our rigorous test looks at key safety requirements such as choking and entrapment hazards, sharp points, strength, structural integrity, security of the harness, and security of attachment to the chair or table. Our interactive comparison tool lists the seats’ features and specifications to help you make the right choice. Our Recommended list will tell you quickly which portable high chairs we rated the best.
