Can I use third-party accessories or parts with the Graco 4Ever DLX car seat?
No, you should not use accessories or parts other than those provided by Graco, except for a thin towel or mat to protect your vehicle seat or a rolled-up cloth. Using unauthorized accessories could compromise the safety and performance of the car seat. (Page 2)
