This stage is set on a flat, floating hard platform in the middle of an arena-like stadium with a single soft platform floating above it. On both edges of the main platform are trampolines that occasionally appear, and the floating platform will also occasionally become a trampoline. If a fighter jumps while standing on a trampoline, they will launch upward with invincibility upon startup and deal damage to any opponent in the way. Small trampolines will also occasionally appear beside the main platform that will automatically launch fighters upward when landed upon. Trampolines can be jumped off of without the high bounce by short hopping. Items can bounce off of active trampolines. There are also two arches above the stage that act as ceilings. Uniquely, the arches are only solid on the bottom sides; therefore, fighters launched above the ceilings are able to fall back through. If items are turned on, ARMS Drones will occasionally carry items onto the stage.
The background consists of a cheering audience of fans dressed in Smash Bros.-themed attire, as well as a screen display. This display shows off visuals representing every playable character in ARMS.
Ω form and Battlefield form
The main platform of the Ω form and Battlefield form is identical to how it appears in the normal form; however, it is resized and reshaped to match Final Destination and Battlefield, respectively. The trampolines on both ledges are also absent. The three soft platforms of the Battlefield form resemble the floating soft platform of the normal form and do not become trampolines. The ceilings above the stage are removed, as well as the other arches in the background. The occasional trampolines that appear to the side of the stage also do not appear.
With hazards off, the trampolines on the stage never activate. The small floating trampolines on either side do not appear, and neither do ARMS Drones. The arches that act as ceilings are still present.
Spring Stadium is a stage in ARMS that is owned and operated by the Spring Gym, and it is the home stage of Spring Man. In ARMS, Spring Stadium is a square, mostly flat stage with trampolines along the perimeter that can be used to jump on for height and bounce opponents off of. In Ultimate, the overall design of Spring Stadium is mostly retained; however, rather than being set on the ground, the stage is set on a floating platform in the middle of the arena with trampolines on the edges that fighters can use to jump off of.
In ARMS, if items are turned on, drones will randomly spawn carrying items that either deal damage to opponents or heal the user. In Ultimate, these drones also randomly spawn carrying items if items are on.
