Graco 4ever extend2fit can extend your kids legs when rear facing so your kids leg wont bent alot. The max weight limitation of rear facing for Graco 4ever is 40 lbs where else Graco 4ever extend2fit can go up to 50lbs. This makes it more safe coz your kids can sit in rear facing mode longer. Rear face is 5x safer than Forward facing.

I have seen a few Graco sold in Aeon but not these models. I have seen Graco 4ever and Graco Extend2fit sold in Midvalley Baby fair a few times. I think the Graco 4ever was sold around Rm1600 to Rm1800. So far I havent seen Graco 4ever Extend2fit sold in Malaysia retails stores or baby fair. Maybe you can try to order it online:
