Thank you for your interest in the SeatMe™!
The major differences between the COMPLETE™ and SeatMe™ include:
1. Our 6-position carriers have a standard buckle waist belt and comes with our lumbar support. The SeatMe™ has a velcro waist belt with a buckle reinforcement. The waist belt on our 6-position carriers fits up to women's US size 22/24 pants, while the SeatMe™ is designed for slender frames and fits up to size 10-12 US women's pants.
2. The SeatMe™ has a rigid seat insert that baby sits on, while our 6-position carriers have more of a classic carrier profile where baby is seated in the fabric of the torso panel.
3. Our 6-positions carriers are one complete carrier unit, while the torso panel of the SeatMe™ can be removed completely and just the waist belt and rigid shelf seat portion can be used, if desired.
Both our 6-position carriers and the SeatMe™ can be used from 7-45 pounds and allow multiple carry positions, including facing in, facing forward, and hip and back carries.
