2015 Mercedes-Benz C-Class: Car Seat Check

The 2015 Mercedes-Benz C-Class underwent a growth spurt during its recent redesign. The sedan grew more than 3 inches in length. Backseat occupants might notice the increase because it translates to nearly 2 additional inches of rear legroom; we certainly noticed this during our Car Seat Check when installing our rear-facing child-safety seats. Our results only apply to the C300 sedan; the C-Class coupe has yet to be redesigned.

What We Like

  • The C-Class has two sets of lower Latch anchors in the outboard seats that are easy to find and use thanks to their design. They sit out in the open with movable rubber flaps covering the anchors. To access the anchors, just push the flaps back. Three tether anchors are found on the C300’s rear shelf.
  • While we had to move the front passenger seat forward to fit the rear-facing infant seat behind it, it was such a small amount that we decided not to downgrade the C300. Our front-seat tester had plenty of legroom and knee room.
  • There was no need to move the front passenger seat forward to fit the rear-facing convertible seat.
  • The only adjustment we made while installing the forward-facing convertible was to raise the head restraint to allow for a better fit of the car seat. This seat was easy to install.

What We Don’t

  • Seat bolsters pushed our high-back booster seat off to the side slightly. Seat belt buckles are on stable bases, but they sit low in the seat bottom cushion, which could make them difficult for young kids to use independently.

Grading Scale

A: Plenty of room for the car seat and the child; doesn’t impact driver or front-passenger legroom. Easy to find and connect to Latch and tether anchors. No fit issues involving head restraint or seat contouring. Easy access to the third row.

B: Plenty of room. One fit or connection issue. Some problems accessing third row when available.

C: Marginal room. Two fit or connection issues. Difficult to access third row when available.

D: Insufficient room. Two or more fit or connection issues.

F: Does not fit or is unsafe.

About Cars.com’s Car Seat Checks

Editors Jennifer Geiger, Jennifer Newman and Matt Schmitz are certified child safety seat installation technicians.

For the Car Seat Check, we use a Graco SnugRide Classic Connect 30 infant-safety seat, a Britax Marathon convertible seat and Graco TurboBooster seat. The front seats are adjusted for a 6-foot driver and a 5-foot-8 passenger. The three child seats are installed in the second row. The booster seat sits behind the driver’s seat, and the infant and convertible seats are installed behind the front passenger seat.

We also install the forward-facing convertible in the second row’s middle seat with the booster and infant seat in the outboard seats to see if three car seats will fit; a child sitting in the booster seat must be able to reach the seat belt buckle. If there’s a third row, we install the booster seat and a forward-facing convertible. To learn more about how we conduct our Car Seat Checks, go here.

Parents should also remember that they can use the Latch system or a seat belt to install a car seat, and that Latch anchors have a weight limit of 65 pounds, including the weight of the child and the weight of the seat itself.
