The Safety 1st TrioFit 3-in-1 Car Seat gives your child a safer and more comfortable ride through three different modes of use. From rear-facing to forward-facing and later as a belt-positioning booster, this extended use 3-in-1 car seat keeps your child snug from 5-100 pounds.The car seat’s first mode is in the rear-facing position from 5-40 pounds. This is great for both newborns and growing toddlers. The comfortable body pillow gives smaller babies a snug fit and is easily removed when no longer needed.Forwarding-facing harness mode keeps your child in a 5-point harness up to 50 pounds. In both rear and forward-facing positions, the convenient harness holders keep the harness in an open position during seating. This makes it easier for you to get your child in and out of the car seat. No more fishing for the harness and clips from behind your child – they’re right there when you need them! The QuickFit Harness offers additional convenience in both rear and forward facing positions by letting you adjust the height of both the headrest and harness in one easy step, with no need to rethread the harness or uninstall the car seat. This makes it simple to give your growing child the best fit.When your child outgrows the forward-facing harnessed mode, it’s simple to remove the harness and use the TrioFit 3-in-1 Convertible Car Seat as a belt-positioning booster all the way up to 100 pounds. The headrest still adjusts easily, letting you ensure that your child gets the best fit.As your tiny baby grows into a big kid, messes are bound to happen, but the car seat pad on the EverFit makes cleanup easy. Machine washable and dryer safe, it is designed with snaps that allow it to come off the seat without removing the harness. With the TrioFit, parents are more comfortable in the car too. In the rear-facing mode, it takes up less room, giving up to 7 inches more leg room for people riding in the front seat.
