Custom Driver's Seat: 'One Size Fits All' Does Not Work Against Back Pain

December 03 2025

For thousands of professionals, from truck drivers to crane operators, sitting is the core of their work. The seat is their office.

Unfortunately, this crucial part of the workplace is often treated with complacency. The cliché 'sitting is the new smoking' emphasizes the risk of prolonged, static sitting, which leads to insidious back and neck complaints, and ultimately to absenteeism and reduced productivity. The standard seats in many vehicles and machines are often no more than a simple cushion, chosen based on price, not on ergonomic suitability.

Trône Seating, a company with over fifty years of experience in the seating industry, is tackling this problem. They do not believe in the idea of 'one solution for everyone,' but advocate for a custom driver's seat that adapts to the individual. Thanks to advanced technologies like electric adjustment with a memory function, the seat becomes a personal and preventive tool.

What is the Biggest Misconception About Ergonomic Seating in the Industry?

The most persistent misconception in the industry is the assumption that the standard seats in machines and vehicles are ergonomic by definition. This is often incorrect. They are installed because they are cheap, not because they optimally support the user's health.

These 'standard' seats usually neglect basic provisions. Crucial settings such as:

Seat Depth Adjustment: Essential for good support of the thighs and preventing circulation cutoff.
Adjustable Lumbar Supports: Necessary to support the natural S-shape of the spinal column.
Correct Armrests: Important for relieving the shoulders and neck.

When people work day in, day out (sometimes six to eight hours long) in these insufficiently supportive seats, the complaints do not arise immediately, but creep in after years of discomfort. Only then do people seek a solution. The general statement that "sitting is unhealthy" is transformed by Trône Seating into the pursuit of dynamic and different sitting; a posture that constantly changes and moves, comparable to the use of an electrically adjustable desk.

How Do Extensive Adjustment Possibilities Contribute to Preventing Back Pain?

Every body is unique: a tall operator needs different support than a shorter driver. A custom seat prevents complaints because it guarantees the perfect, supportive posture. This is achieved through a vast number of adjustment possibilities that adapt the seat to every body part and every body size.

Trône Seating offers, for example, seven to nine adjustment options to tailor the seat exactly to the user, specifically for:

The length of the legs (seat depth and seat height).
The hollow and curvature of the back (lumbar support and backrest angle).
The position of the shoulders and neck (headrest and armrests).

Due to this versatility, the seat is always custom-made for the individual. This is the best prevention against physical complaints. A seat must follow the person, not the other way around.

Concrete Tips:

Before choosing a seat, you can use the following guidelines to check whether a seat is basically well adjusted, or whether it needs to be replaced:

Adjustment Point	Ergonomic Recommendation	Why it is Important
Seat Depth	Approximately 2 to 4 fingers should fit between the front of the seat and the back of the knee.	Prevents blood vessels in the legs from being pinched off and optimally supports the thighs.
Seat Height	The hips are slightly higher than the knees (open hip angle, ideally $100^{\circ}-110^{\circ}$ , with the feet flat on the floor.	Maintains the natural S-shape of the back and reduces pressure on the intervertebral discs.
Backrest	The lumbar support (bulge in the backrest) is at the height of the belt.	Supports the lumbar spine to prevent slouching.
Armrests	The armrests are set at elbow height, so the shoulders are relaxed.	Relieves neck and shoulder muscles during prolonged steering or operating buttons.

If your current seat does not allow these basic adjustments, the chance of complaints is significantly higher.

Why is the Combination of Electric Adjustment and a Memory Function so Crucial?

In work environments with shift work (consider port cranes in the Europoort or delivery vans at Schiphol), it is common for multiple employees to use the same machine and thus the same seat. This is where the technological innovation of an electrically adjustable seat with a memory function proves its added value.

The Challenge in Practice:

When a new shift starts, they need to get to work quickly. If the seat has to be adjusted manually with seven or eight levers, they waste valuable time and, more importantly, there is a high chance of setting the seat incorrectly because they are rushed. Even a small, incorrect adjustment can cause back problems in the long term.

The Solution from Trône Seating:

The memory function ensures that every driver or operator can set their perfect, personalized position with the push of a button. This:

Accelerates the start of work: No puzzling with levers.
Guarantees the correct posture: The setting is saved and always correct, which prevents back pain.
Offers dynamic seating comfort: The quick adjustability makes it easier to switch between different, but ergonomically correct, postures throughout the workday.

This technology serves the user; it makes the seat not only individually adjustable but also quick and consistent to set.

How Can Companies Make the Choice and Adjustment of the Seat Risk-Free and Personal for Their Employees?

The involvement of the end-user (the driver or operator) is very important. A seat is often seen as an unimportant part. When a new machine is delivered, the operation of the engine and electronics is extensively explained, but the seat is often skipped. This must change.

Companies can make the switch to a better driver's seat personal and accessible by:

The Trial Period: The ultimate guarantee is the possibility of a trial sit. Trône Seating, for example, offers a 28-day trial period. The seat and the person must 'decide' together whether it is good enough. If a seat is not satisfactory after this period, it can be adjusted or exchanged. This guarantees that the seat truly fits the user and their work.
Clear Adjustment Instructions: Providing a clear manual and instructions, often through prevention officers or a specialist from the seat supplier. This ensures that all seven to nine settings are used correctly to adopt the optimal posture.
Focus on Sustainable Employability: By investing in a better seat, companies directly invest in the health of their employees and contribute to the focus on the Working Conditions Act (Arbowet) and sustainable employability. In a tight labor market, retaining good personnel by providing them with a 'luxurious, comfortable, and better seat' is a smart move.

What Influence Do Vibrations Have on the Driver's Health, and How Can a Seat Help?

Especially in vehicles on solid tires and machines driving over uneven terrain, such as forklifts, construction machines, or tractors, exposure to vibrations is a huge strain on the body. These vibrations and shocks go straight through the back and can cause serious complaints to the spinal column.

A high-quality, ergonomic driver's seat plays a vital role in filtering these vibrations.

Suspension and Damping: Good seats have advanced suspension systems (horizontal and vertical) and steplessly adjustable damping to minimize the impact of shocks.
Prevention: The ergonomics of the seat absorb these shocks and prevent the body from having to process them itself.

This is a trend that is gaining increasing attention: the focus on vibration prevention as part of the general ergonomic seating solution. Companies realize that after three to five years of intensive use (and vibration absorption), the seat is due for replacement or needs a better solution to keep the personnel vital. The investment in a superior seat is therefore a direct investment in the reduction of absenteeism and unnecessary pain.
