Original PIPA Base vs RELX Base
PIPA aire: Original PIPA base with rigid lower anchors and load leg; no anti-rebound panel. PIPA RX and aire RX: RELX base with adjustable rigid anchors, load leg, anti-rebound panel, and approved recline settings. All three carriers also allow approved baseless seat belt installation.
What Makes the PIPA urbn Different?
The PIPA urbn has rigid lower anchor connectors built into the carrier, so no separate base is needed. It cannot be used with a PIPA or RELX base. It can also be installed with a vehicle seat belt following its manual. The newer urbn model shown in Gina's video supports 4–30 lb and up to 29 inches.

Frequently Asked Questions
Is PIPA aire RX always better than PIPA RX?
No. The aire RX adds premium materials and magnetic harness holders, but the RX has a two-position crotch buckle that may be important for your child's fit.
Can these seats be installed without a base?
All four models have approved baseless installation methods. The urbn also has integrated lower anchor connectors. Follow your seat and vehicle manuals.
Can PIPA urbn use a RELX base?
No. PIPA urbn is not compatible with any separate PIPA base.
When should I remove the infant body support?
For the models Gina demonstrates, the entire body support pillow must be removed after 11 lb, not only the foam wedge. Check your specific model's manual.
Which PIPA is lightest?
In Gina's equipped-seat comparison, PIPA aire weighed 7.8 lb, followed by aire RX at 8.4 lb, RX at 8.6 lb, and urbn at approximately 9 lb.
