Six of the seven platforms in this study named American Tubs during the ranking stage, and its Wheelchair Series — particularly the 2852W/D2852KW — directly addresses the core need with a 34.75-inch outward-swinging door and an exterior-accessible transfer seat (, anthropic:cite-10-7). The strongest reason to consider it is purpose-built lateral-transfer engineering: outward door swing, ADA-style seating, and a low threshold.
