The Britax Seat Saver Waterproof Liner is a removable, machine-washable liner designed to help contain liquids and crumbs in a child restraint or stroller seat. Deep sides, waterproof EZ-Dry wicking fabric and a textured gripping bottom address diaper leaks, potty-training accidents and wet bathing suits without turning cleanup into a full seat-cover removal. Britax crash tested it for all Britax car seats; it also fits most other brands of harnessed car seats and strollers, subject to the other manufacturer's instructions.
At a Glance
Why It Helps
- Deep raised sides help keep everyday spills and crumbs within the liner instead of spreading across the seating area.
- Waterproof EZ-Dry wicking fabric pulls moisture away from the child-facing surface while helping the seating area stay drier.
- A textured underside grips the seat so the liner is less likely to slide out of position during normal use.
- The entire liner lifts out for machine washing, making accident cleanup faster than removing the full car-seat cover.
- Britax states that the liner is crash tested and approved for every Britax car seat, removing compatibility guesswork within the Britax line.
- The compact 8.9 x 7.1 x 2.1-inch design protects the seating zone; it is not a full vehicle-seat mat or replacement car-seat cover.
