Chicco’s Travel Seat portable high chair has rubberized grips that won’t mark tables and firmly attaches to tables between .75 and 4 inches thick (with a collar up to 6 inches). It can be locked in place on the table. Weighing in at only seven pounds, the Chicco Travel Seat also folds up compactly, so it’s easy to take on a trip and can even fit in the pouches of some strollers.
A note about safety: a measure of caution should be used when using the Chicco Travel Seat on a table that you haven’t used before. Since the seat accommodates children up to 37 lbs., you might want to test it out first, especially on tables with center posts or lightweight restaurant tables, as they may tip. Just use common sense and you will be fine.
