Overview
The BubbleBum BBTPRT01-US is a forward facing booster seat rated up to 110 pounds, installed with the vehicle seat belt rather than latch. At 5.5 pounds and a packed footprint of 15 by 13.5 by 6 inches, it is built to be light and portable.
BubbleBum is known for inflatable, backless booster seats designed to pack flat for travel or carpooling, and the listed weight and dimensions here are consistent with that style, though the listing does not explicitly confirm an inflatable design.
- 110 pound weight capacity
- 5.5 pound seat weight
- Seat belt installation
- 15 by 13.5 by 6 inch packed footprint
Who it's for
Fits parents who need a portable booster for carpools, grandparents' cars, or travel, given its light weight and compact packed size. Parents who want a high back booster with side impact wings for a younger or smaller child should look elsewhere, since this is a forward facing, seat belt installed booster.
