Cobblestone Stairs are crafted from six cobblestone blocks in a stair-shaped triangle, yielding four stairs per recipe — same triangle layout as every other stair variant. Cobblestone itself comes directly from mining stone with any wood-tier or higher pickaxe, so this stair option requires zero processing beyond the initial dig: collect cobble, craft, place. That low barrier makes it the first stair material most players ever use in survival.

The rough chunky texture suits medieval castles, dungeon corridors, mountain fortresses, and any structure that should look hand-built rather than industrially polished. The mossy cobblestone variant pairs especially well for ageing — replacing one in five with the mossy version reads instantly as old or abandoned construction. Standard stair behaviour applies: half-block riser, automatic corner formation, top-half ceiling placement, walking-up without jumps. Like all cobblestone family blocks, the stair has no fire flammability and a moderate blast resistance, useful when the build needs to handle creeper damage in addition to looking the part.
