The Graco Extend2Fit 3-in-1 with Anti-Rebound Bar rear-faces from 4 to 50 lb, forward-faces with the harness from 26.5 to 65 lb and up to 49 in, and becomes a high-back booster for 40 to 100 lb, 43 to 57 in, at least 4 years old. The bar is for rear-facing only. It expires 10 years after the date of manufacture.
It suits a family that wants the Extend2Fit 3-in-1 limits plus an anti-rebound bar for the rear-facing years and a cover that comes off without uninstalling the seat. The trade-off is depth: Graco lists it at 26.75 in deep and 21.9 lb. The standard Extend2Fit 3-in-1 has the same mode limits, no bar, and is listed at 20.75 in deep and 20.61 lb.

This seat covers 3 stages, and a child has to meet every limit of the stage they are in. Graco gives it a 10-year life from the date of manufacture, so check the date label before using a hand-me-down.

A child must meet every limit for the mode they use. The labels on your seat and its manual are the final word.
Every install is a fit between one seat and one vehicle. Read both manuals, and use a free inspection station if anything is unclear.
At 19 in at its widest, measure your back seat before counting on three across. It weighs 21.9 lb, which matters if you will move it between cars or carry it through an airport.

The manual calls the bar optional and allows it only in rear-facing mode. Insert its ends into the holes on the front of the seat until it clicks, with the bar rising upwards, never dipping downwards. Do not use it in forward-facing or booster mode; remove it by pressing the buttons on both sides of the seat at the same time. Do not carry the car seat by the bar. Clean it with mild soap and water only, without bleach or other chemicals, and avoid spilling drinks on it.

Rear-facing, place the seat in the 1st, 2nd, 3rd or 4th recline position and route the lower anchor attachment or vehicle belt through the rear-facing belt path. Do not use the lower anchors rear-facing for a child over 40 lb. Children under 26.5 lb must ride rear-facing. Forward-facing, take the bar off, use recline position 6 for a child over 40 lb, and do not use the lower anchors for a child over 45 lb. The tether is used in addition to the lower anchors or the vehicle belt when forward-facing.

Booster mode is for children 40 to 100 lb, 43 to 57 in tall and at least 4 years old, with the bar removed and the seat in recline position 6. The child is held by the vehicle lap and shoulder belt. The manual says the seat is certified for aircraft use with the harness system, on forward-facing aircraft seats, and is not certified as a booster on aircraft because aircraft do not have shoulder belts. Contact the airline about its own policy. Stop using the seat 10 years after the date of manufacture.

Graco says the Rapid Remove cover comes off in 60 seconds without uninstalling the seat or removing the harness, and that it is machine washable. Wash the seat pad in cold water with gentle soap on a delicate cycle and drip-dry, without bleach. Clean the buckle in a cup of warm water, pressing the red button several times, without soap and without submerging the buckle strap. The harness is surface wash only, and the harness and LATCH straps must not be immersed. Metal and plastic parts may be cleaned with mild soap and cool water.
