Mercedes-Benz CLA Seat Replacement Parts

The Mercedes-Benz CLA ran as a single generation (C117) from 2013 to 2019, with a facelift arriving in 2016, so a 2014 seat and a 2017 seat sit either side of that facelift boundary. The generation is the same, but trim changes around the 2016 facelift mean seat styles and upholstery fixings may differ, so you should confirm with the breaker whether the specific seat from the donor car crosses the facelift boundary cleanly for your trim. Never assume fitment without checking your registration details against the donor vehicle.

Trim level matters for CLA seats because Mercedes offered different seat styles across grades — SE and Sport models typically came with standard cloth or part-leather seats, while AMG Line models featured more heavily bolstered sport seats with different mounting points and side-bolster airbag configurations. Fitting an SE seat into an AMG Line car (or vice versa) may mean a cosmetic mismatch in style and material, and the airbag wiring plugs may differ, so confirm compatibility with the breaker against your registration. Because seat-mounted side airbags are safety-critical and single-use after deployment, professional fitting is strongly recommended.

Yes — always specify nearside (NS, left as you sit in the car) or offside (OS, right as you sit in the car) when ordering, as the seats are handed and not interchangeable. On models with seat-mounted side airbags, the airbag module is built into the outer bolster of each seat, making it even more important to get the correct side. Confirm the side and airbag specification with the breaker against your registration before purchasing.

No — the CLA moved to an all-new platform with the second generation (C118) from 2019 onwards, and the seat mounting points, rail systems and wiring connectors are not shared with the C117 (2013–2019). You should only source a seat from the matching generation for your car. Always confirm the exact donor vehicle details with the breaker against your registration.

Engine choice has no bearing on seat fitment for the CLA — what matters is the generation (C117 2013–2019 or C118 2019 onwards), the trim level, and the side (NS or OS). A CLA 180 and a CLA 250 of the same generation and trim will use the same seat. Confirm generation and trim with the breaker against your registration to make sure you get the right seat.

Yes — CLA seats commonly contain side-impact airbag modules built into the outer bolster, and the seat belt pretensioner is also integrated into the seating system on many variants. Both airbags and pretensioners are safety-critical, single-use components that must be in undeployed condition, and you should confirm airbag module compatibility with your car's specific SRS system and pretensioner variant with the breaker against your registration rather than assuming they match. Professional fitting by a qualified technician is strongly recommended for any seat containing airbag or pretensioner components.
