ThyssenKrupp Access manufactured several different stair lifts including the Levant, The Levant Comfort, the Citia and the Flow curved lift before ceasing operations in the United States. The Levant comfort is very similar to the standard Levant but will have a different seat assembly. The ThyssenKrupp Access Flow is designed for curved stairs and will have a white or cream color rail. ThyssenKrupp Access announced the closing of all its US operations in 2012. Other stair lift models discontinued by ThyssenKrupp Access were the Excel and the Stair-Glide. While we may be able to repair a TK Access lift parts are difficult to locate.
