The Britax cup holder allows your child to bring along their favorite drink in the car without worrying about where to put it. The Britax cup holder fits multiple sized containers including sippy cups, water bottles, juice boxes and drink pouches. It can be attached to either the left or the right side of the seat and is dishwasher safe (top rack only). This cup holder is exclusively made for use on Britax convertible car seats manufactured after June 2010 including ClickTight models (excludes Britax classic models).
