2025 ATTO 1 rear seats split 50:50: do not select backrests or upholstery as 60:40

A rear-backrest repair request receives images of a larger and smaller section in a 60:40 layout. On the Australian MY25 ATTO 1, checking the manufacturer’s 50:50 split first improves backrest, upholstery and position identification and avoids an unhelpful enquiry cycle.

Use the explicit 50:50 entry rather than a familiar layout

Both Essential and Premium list Split folding rear seats 50:50.[Manufacturer specification][Q09] This identifies the original rear-seat layout, but does not explain separate supply of cushions, backrests, locks and hinges.

The ratio cannot establish each backrest section’s dimensions or mounting points, or prove that both sides are identical. Nor can another BYD model’s layout fill the catalogue gap.

Specify side, area and surface material

For damaged upholstery, photograph the exact area and original material. For a backrest or folding complaint, separately retain the position, actual response and inspection findings. “Half a rear seat” leaves the supplier guessing the side or layer.

A 50:50 split does not establish interchangeability between left and right sections or between trims. A matching ratio begins the check; it is not a part-number conclusion.

Folding equipment does not provide lock diagnostics

Whether a seat folds, is damaged or locks correctly requires vehicle inspection and service information. The product table gives no adjustment, locking or replacement criteria. One folding response is no basis here for deciding to replace a backrest or lock.

Scope and verification
