What Is a Brake-Loaded Caster (Sit Lock Caster)?
The Reliable Solution for Stability in Medical and Technical Seating
1. Not Every Chair Should Move—Stability Matters More
In certain professional environments, the ability for a chair to stay in place is more important than how smoothly it rolls. When a user is performing precise tasks, receiving medical attention, or assisting others, a moving chair can be a liability.
To meet this need, Enjoying Go offers the Brake-Loaded Caster, also known as a Sit Lock Caster or Compression Brake Caster. This caster type automatically locks the chair when someone sits down, and unlocks it when the chair is unoccupied, making it the perfect solution for safety-critical or task-focused environments.
2. How It Works: Automatically Locks When Seated
The Brake-Loaded Caster operates in reverse compared to conventional caster wheels:
-
Unoccupied (no weight) → chair moves freely
-
Occupied (with weight) → wheels automatically lock
The locking mechanism is triggered by the user’s weight, providing automatic stability without any manual adjustment. This reduces human error and enhances safety in environments that demand full focus.
3. Ideal Applications: When Stability Is a Must
Brake-Loaded Casters are best suited for environments where the chair must stay still while in use and be mobile only when not in use. Typical applications include:
-
Medical examination chairs – ensure patients remain stable during diagnosis
-
Patient companion chairs/caregiver seating – improve fall prevention in hospitals
-
Children’s high chairs – reduce the risk of tipping or slipping
-
Laboratory or testing station chairs – stabilize seating during delicate operations
-
Beauty or dental treatment chairs – avoid unintended rolling during procedures
-
Technical workstations – ensure safety and precision for seated operators
In all these cases, stability isn’t optional—it’s essential.
4. Three Key Benefits of Brake-Loaded Casters
