We purchased this booster seat to replace our large high chair since it takes up a lot of space. Well, we still used our high chair for over 9 months after we bought the chair so that doesn't look very good. While it is simple and convenient, that is also its downfall. The straps that hold the child are very difficult to loosen, but the straps that hook the seat to the chair are difficult to keep tight. I like that the height of the chair is adjustable. It is nice to have the attachable tray, but I think it is too low. It would be nice if it was a few inches higher. We have used this when we travel, and I think it is very convenient for times like this. However, if I could, I would go back and purchase a better booster seat as this does not seem like something we will want to use long term. I will likely buy a new one with our next child and use this as back up for when family visits.
