Very good booster seat
We use this seat instead of a high chair in our home to save space and it works well for every day use. Our baby has used it since able to sit with apparent comfort. The two straps are enough to securely attach it to any chair. It does the job perfectly well and is inexpensive. It doesn't pack down as small as some models, but it's light and easy to bring with us out and about. I'm considering buying one to keep at home and another to keep in the car, just to avoid unbuckling it so often since I do use it as a daily high chair. The round "cup" area of the tray doesn't do much for holding a cup or a pile of cheerios in position but that's the fault of an uncoordinated baby. The whole thing is very easy to clean.
ProsSturdy, simple, inexpensive
ConsTakes longer to get set up than something you could slide on and attach to the tabletop.
