The type of seat suspension in buses, specifically the difference between spring seats and other types, directly correlates with the prevalence of sleep disorders among drivers. This human factors research insight is drawn from a 2024 study published in International Journal of Environmental Health Engineering. Using Quantitative observational study with 62 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Designers must consider the long-term physiological effects of component choices, such as seat suspension, on the primary users of a product.

Key Findings
- 0146.77% of drivers reported bad sleep quality.
- 0269.35% of drivers suffered from MSDs in at least one body part.
- 03Drivers whose buses had spring seats were more likely to experience sleep disorders (OR = 3.17).
- 04Increased driver age was associated with decreased good sleep quality (OR = 0.9).
Application
Design takeaway
Designers must consider the long-term physiological effects of component choices, such as seat suspension, on the primary users of a product.
How to apply
When designing vehicle interiors or selecting components for vehicles, prioritize ergonomic features that minimize vibration and provide adequate support.
Project actions
- 01Investigate the ergonomic properties of different seating options for long-duration tasks.
- 02Consider how material choices for seating can impact user comfort and health over time.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Utilized standardized measurement tools for noise, vibration, sleep quality, and MSDs.
- +Employed statistical analysis to identify significant correlations.
Limitations
The sample size is relatively small, and the study focuses on a specific geographic location, which might limit the universal applicability of the findings.
Reliability & validity
The use of standardized questionnaires and measurement protocols (ISO standards) enhances the reliability and validity of the findings. However, the observational nature and specific context may limit generalizability.
Think critically
To what extent can a single component, like a bus seat, be held responsible for complex health issues like sleep disorders and MSDs, given the multitude of other lifestyle and work-related factors involved?
Design Principles
"User comfort and health should be a primary consideration in the design of vehicle interiors, particularly for professional drivers with long working hours."
This highlights how seemingly minor design choices in vehicle interiors can have profound physiological and psychological impacts on users. For design, it underscores the importance of considering the long-term health and well-being of users when designing or selecting components for transportation systems.
What This Means for Your Design
The seats in buses can really affect how well drivers sleep and if they get aches and pains. Buses with older spring seats seem to make sleep problems worse.
How to use in your project
- 1.Use this insight to justify design choices related to user comfort and health in your product development.
- 2.If your product involves seating or prolonged use in a vehicle, cite this study to support your ergonomic considerations.

Paragraph starter
Research indicates that specific design elements within vehicles, such as the type of seat suspension, can significantly influence user health. A study on bus drivers found that those using buses with spring seats were more likely to experience sleep disorders, highlighting the direct impact of ergonomic design on physiological well-being (Rahimimoghadam et al., 2024). This underscores the critical need for designers to prioritize user health and comfort through thoughtful material selection and component design.
