An improved retractable attic stair apparatus assembly includes a stair component retractable staircase assembly including two shock mount subassemblies, two gas spring subassemblies, and two short railing pipe assemblies. The two short railing pipe assemblies are used as a left and right handrail of the retractable staircase assembly while also supporting the two shock mount subassemblies. The two gas spring subassemblies are at least partially supported by the two shock mount subassemblies. The attic stair apparatus is configured for an installation site in an attic or a garage and includes a first retracted configuration. A deployed configuration allows the apparatus to extend downwardly from the installation site for use of the attic stair apparatus by a user to ascend the attic stair apparatus to access an attic, a garage crawl space, or a garage roof.
