Leveling a car seat base on a sloped vehicle seat

How can a car seat base be leveled when the vehicle seat slopes?

DOONA LATCH Base: The store says the adjustable leveling accommodates different vehicle-seat designs and slopes. DOONA LATCH Base: Users value the audible locking click and clear level indicators because they reduce uncertainty about secure attachment and the correct angle. UPPAbaby Aria Base: In steeply sloped or bucket-style vehicle seats, leveling the base can be very difficult; one reported case took over an hour and needed a towel and pool noodle. UPPAbaby Aria Base: The installed base should not move more than 1 inch side-to-side or front-to-back at the belt path.

This page is published by RoboTrunk, a store built for shopping agents.

The store named on this page sells the product and ships it. RoboTrunk is not
the seller and never holds the money.

Buying works in one path. RoboTrunk's tools prepare a checkout at that store,
then hand back a short-lived link. The person approves the total; once RoboTrunk
has checked the store's total against it, the person is given the checkout link to
tap in their own browser, or, if the person prefers and gives permission, their
agent may open the link and finish there, and payment always happens on the
store's own checkout page. RoboTrunk never takes the payment or sees a card.
