Office Chair Hover Function

Office chairs with a hover function can achieve stable retention of the recline angle through specific chassis designs. Currently, some ergonomic chairs on the market have been optimized technologically to maintain a stable hover state without locking the angle when users lean back. The core principles and functional features are as follows:

1. Realization Principle of the Hover Function

The hover function mainly relies on the damping adjustment system of the chassis. Taking the Sihoo Doro C500 as an example, its sixth-generation space chassis adopts infinite damping adjustment technology, controlling the resistance during reclining through mechanical structures or pneumatic/hydraulic devices. Users can adjust the damping intensity of the chassis according to their body weight (e.g., differences in reclining force required by 50kg and 90kg users) or usage habits (e.g., different inclination needs for office breaks and deep rest). When the reclining force balances with the user's body weight, the chair can hover at any angle without manual locking.

2. Types of Hover Functions

1. Infinite Hover
   For example, the Sihoo Doro C500 supports continuous adjustment of reclining damping, allowing users to precisely control the reclining force and achieve a smooth transition from slight reclining to near-lying flat. There are no fixed gear restrictions for the hover angle, adapting to diverse usage scenarios.

2. Multi-gear Locking + Arbitrary Hover
   Some models (e.g., the Sihoo Doro S300) offer four locking gears (e.g., 90° for office work, 110° for reading, 130° for leisure, and 150° for lying flat) while also supporting arbitrary angle hovering in the unlocked state. Users can choose a fixed gear to maintain a stable posture or freely adjust the reclining angle and hover, balancing flexibility and safety.

3. Core Advantages of the Hover Function

1. Enhanced Safety
   Traditional office chairs may suddenly topple due to gravity imbalance when reclining without locking the angle. The hover function balances gravity through the damping system, allowing stable retention even without locking, preventing accidents.

2. Optimized User Experience
   Users do not need to frequently adjust the locking gears and can naturally lean back to a comfortable angle and hover according to their body feedback, reducing operational interference. This is especially suitable for office or rest scenarios that require frequent posture changes.

3. Increased Adaptability
   The infinite adjustment design can match the needs of users with different body types. Lightweight users can achieve easy reclining by reducing the damping, while heavyweight users can increase the damping to prevent rapid reclining, enhancing the product's universality.

4. Technical Challenges and Solutions

The realization of the hover function requires addressing issues of damping stability and service life. High-end models ensure the precision and durability of damping adjustment by adopting high-strength materials (e.g., aerospace-grade aluminum alloy chassis), optimizing mechanical structures (e.g., dual-spring systems), or introducing pneumatic/hydraulic buffering technologies, preventing damping attenuation or jamming after long-term use.
