An All-Terrain Upright Walker is designed to help one traverse a variety of otherwise challenging surfaces (e.g., gravel, sand, dirt, grass) with minimal strain on the back, neck, and shoulders. Being able to walk standing upright aligns the spine more correctly and engages the core muscles, reportedly enhancing balance and stability. Features of both the Elenker and the OasisSpace walkers include: height-adjustable handlebars; padded armrests; large-diameter, non-slip tires; breathable mesh seat plus backrest; foldability; large storage bag; and rear wheel-locking handbrake.
