Second Hand Mercedes-Benz GLB Seat

The Mercedes-Benz GLB (X247) launched in 2019 and has run as a single generation through to the current model, so a 2020 seat and a 2023 seat are from the same generation and are likely to be compatible in principle. However, Mercedes introduced a facelift for the GLB around 2023, which can bring interior trim and upholstery updates, so whether a pre-facelift seat crosses that boundary cleanly is something you should confirm with the breaker against your registration before buying.

Yes, trim level genuinely matters for GLB seats because upholstery material, bolstering, and seat design vary between grades — for example, Sport seats differ visually and in construction from those on AMG Line models, which typically feature more pronounced side bolsters and different fabric or leather finishes. A seat from a different trim will physically fit the mounting points but may look noticeably out of place, so make sure you match the trim as closely as possible and confirm the exact spec with the breaker.

Yes, driver's side (OS — offside) and passenger's side (NS — nearside) seats are not interchangeable, as they are mirror-image in construction, mounting, and any integrated electronics. Always specify NS or OS when getting a quote from a breaker.

No, the engine has no bearing on seat fitment for the GLB — seats are determined by generation, trim level, and side, not by whether the donor car was a diesel or petrol. You can safely disregard the engine when searching, which gives you a wider pool of donor vehicles to choose from.

Yes — GLB seats can contain side-impact airbags and the seat belts may incorporate pretensioners, both of which are safety-critical and single-use once deployed, so you must verify with the breaker that neither has been triggered in the donor vehicle. Airbag module compatibility with your specific SRS system and pretensioner variants are things you should confirm with the breaker against your registration rather than assume. Professional fitting is strongly recommended for any seat containing airbag or pretensioner components.

No — the GLB (X247), GLA (H247), and GLK are distinct models with different seat bases, mounting points, and interior architecture, so seats are not interchangeable between them. Always source a seat specifically listed for the GLB X247 generation, and confirm compatibility with the breaker using your registration.
