I know, I know, booster seats aren't exactly age-appropriate for babies, but I have a feeling there are more than a few of you out there with tots who've outgrown their highchairs—or who've been kicked out, thanks to a new sibling who requires a little more support. In any case, the fact is: There are a lot of good-looking, smart-functioning alternatives to a stack of phone books. (Though I actually find this foam phone book booster quite clever.) So whether your household has a little bottom currently in need of a lift (and we could all use a backside lift, couldn't we?) or you're just a plan-ahead kind of mom (bless you!) who's already keeping her eye out for future needs, here are a few sleek seats to get you started.
