DOF Reality H4 4-Axis Motion Simulator Platform
Enhanced 4-Axis Motion with Integrated Heave
The DOF Reality H4 4-Axis Motion Simulator Platform is designed for advanced home simulation setups that benefit from additional physical feedback. Its four-axis motion system incorporates heave alongside the platform's other movement axes, adding vertical motion to create a more comprehensive simulation experience.
By combining vertical movement with other motion cues, the H4 can reproduce a wider variety of simulated events, including elevation changes, surface irregularities, turbulence, jumps, and acceleration transitions.
Four-Axis Motion with Heave
The H4 adds a dedicated heave axis for vertical movement, complementing the platform's other motion capabilities.
This allows the system to provide physical feedback associated with:
-
Heave – Vertical movement
-
Pitch – Forward and backward tilting
-
Roll – Side-to-side tilting
-
Additional coordinated motion cues depending on the simulation
The combination of these movements provides a more complete physical response than platforms without dedicated vertical motion.
Enhanced Simulation Feedback
The H4 is designed to translate simulation data into controlled physical movement. Its integrated heave functionality can add movement cues associated with:
These effects can complement the visual and audio elements of the simulation by adding corresponding physical feedback.
Designed for Advanced Home Simulation
The H4 is built for home users looking to enhance their simulator with additional motion capability. Its four-axis configuration provides a balance between expanded physical feedback and a practical home-oriented setup.
It is particularly suited to users who want vertical movement included in their simulation experience without moving to a more complex multi-axis platform.
Versatile Simulation Applications
The DOF Reality H4 can be incorporated into a variety of immersive simulation environments, including:
Balanced Motion and Performance
The H4 combines its four-axis architecture with a design focused on controlled and consistent motion response. The addition of heave gives users another dimension of physical feedback, helping create a more detailed relationship between simulated events and platform movement.

Developed using DOF Reality’s experience in motion simulator engineering since 2014, the H4 brings advanced motion capability into a compact and quiet platform suitable for home environments. The footprint is similar to the DOF Reality H3 and measures approximately 3 × 5.2 ft (100 × 150 cm) with a height of 2 ft (60 cm), making it well suited for use in limited spaces.
The platform is constructed from high-strength European steel to ensure stability and long-term durability. All mounted components—including the seat, steering wheel, pedals, and flight controls—move together as a single unit. This design allows motion feedback to be delivered through natural body pressure points, enhancing realism beyond visual cues alone. The H4 is compatible with racing peripherals, flight simulation controls, and major VR headsets.
Designed for sim racing and flight simulation use, the H4 provides immersive physical motion intended to closely reflect in-game movement, offering a realistic motion experience for home users.
