A rolling soft sided luggage case enclosing a volume and having opposing sidewalls, the sidewalls being supported by a tubular strut frame structure independent of the wheel housings mounted at the rear corners of the case. A straddle bracket affixed to a middle region of a side edge of the structural base joins the rear sidewall strut to the rigid base without engaging the wheel housing in order to facilitate ease of construction and repair of the wheel bracket. The levered portion of the base to which the wheel housing is affixed serves as a dampened swing arm on which the luggage case is sprung in order to isolate the structural frame of the case from bumps while being rolled and to and dampen shocks to the structure.
