A retractable cabinet device has a base, two tracks and a cabinet. The tracks are mounted on the base and each track has a rail slot defined in the track and having a convex top surface. The cabinet is mounted movably on the tracks, selectively extends out or retracts back above the base and has two front wheel assemblies and two rear wheel assemblies. The front wheel assemblies contact the ground. The rear wheel assemblies are rotatably and slidably mounted respectively in the rail slots of the tracks. The retractable cabinet device is arranged in a compact and retracted configuration when idle to occupy less space and therefore facilitates use of indoors space where the retractable cabinet device is placed. Furthermore, the retractable cabinet device is stable and may be positioned in the using extracted or retracted configuration. |
