Used Mercedes-Benz GLA Headrest

This is a critical fitment boundary to watch: the GLA first generation (X156) ran from 2014 to 2019, while the second generation (H247) launched for 2020, so a 2015 and a 2019 GLA are both X156 and share the same generation. Within the X156 generation, headrests should correspond provided the trim level and seat style match, but confirm the exact part with the breaker against your registration as seat upholstery and headrest profiles can vary by trim.

No — a 2021 GLA is second-generation H247 (2020 onwards), while a 2019 GLA is first-generation X156 (2014–2019), and these generations have completely different interior designs and seat structures. A headrest from one generation will not interchange with the other, so make sure you specify your generation clearly when requesting a quote from a breaker.

Trim level does matter for GLA headrests because different trims can have different seat types — for instance, AMG Line models often feature sportier seats with differently shaped headrests compared to SE or Sport grades. Always tell the breaker your exact trim level alongside your registration so they can match the correct seat and headrest style; fitting a headrest from a different seat design may mean it does not locate correctly or looks out of place.

Headrests themselves are generally not side-specific, as they simply post into the seat-back regardless of whether the seat is on the nearside (NS) or offside (OS). However, if the headrest is part of an integrated active head restraint system within a specific seat, the seat mechanism may differ between driver and passenger sides, so it is worth confirming with the breaker that the headrest and any attached mechanism matches your seat exactly.

No — the engine has no bearing on headrest fitment whatsoever, as headrests are part of the interior trim and are the same across petrol, diesel, and hybrid variants within the same generation and trim level. Focus on getting the generation (X156 2014–2019 or H247 2020 onwards) and trim level right, and the breaker can then match you correctly.

Give the breaker your full registration number, the generation of your GLA (X156 first-gen 2014–2019 or H247 second-gen 2020 onwards), your trim level (such as SE, Sport, AMG Line, or AMG Line Premium), and the row and position of the seat the headrest belongs to (front or rear). Colour and upholstery type — cloth, MB-Tex, or leather — will also help ensure a visual match, as used headrests should ideally align with your existing interior.
