In some cars it is endless search for a pleasant seating position.

No matter how long you spend with the seat adjustment and whether you move the seat forward, backward or higher: really comfortable seating is not an option.

The car seat developers recognize this problem.

Large, small, thick, thin: a car seat must be suitable for people of very different stature and meet strict safety requirements.

For example, the seat must hold you well in place, but an airbag also shoots out of the backrest in the event of a collision with more and more seats.

Therefore, particularly intensive testing is required to develop the ideal car seat.

"A lot of things are calculated on the computer, but we still build a large number of prototypes and we also test the seats ourselves," explains Sascha Ring of Volkswagen's development department.

"During the many test rides, the test drivers sometimes have to endure a lot."

Ring explains the secret to a good chair.

"I like it when the side bolsters offer good lateral support, but at the same time offer enough freedom of movement."

When assessing a chair, it also comes down to matters that initially seem unimportant.

“If you look at the seams on some side bolsters, you can see how important their correct positioning is. to press."

This is how you sit, according to an experienced driver

In many cases, adjusting the chair properly is no longer done by hand.

Electric motors ensure that the backrest and seat are in the desired position.

“Even if I only have a short drive to go, I check that the seat adjustment is correct,” says German racing driver Benjamin Leuchter (33), who also works as a driving instructor at Volkswagen.

He knows better than anyone how important it is to have a good sitting position.

"The backrest should be upright, the seat should be pushed forward reasonably far and the legs should be slightly bent so that I can depress the brake pedal deeply without the risk of sliding forward over the seat."

Finally, Leuchter takes a look in the rear-view mirror, because according to him it is also part of a good sitting position.

This can help with a weak back

The German organization Aktion Gesunder Rücken (AGR), supported by physiotherapists, has a checklist that assesses the seating quality of car seats.

AGR also has a quality mark that is awarded to chairs that meet these conditions.

German car manufacturers in particular have the so-called AGR seats on the option list.

The organization assesses whether the basic structure of the chair supports the spine properly.

She also looks at the quality of the upholstery, the operation of the headrest, the adjustment options of the seat and the accessibility of the controls.

The organization also provides tips on its website that can prevent pain while driving.

Think of stretching exercises that you can do during a layover to relieve the back during a long ride.

That is good for the body and ultimately also for road safety.

How about the headrest?

Headrests must strike a balance between comfort and safety.

Of course, it is not pleasant if your head constantly hits the headrest, but a limited distance from the head ensures that the spine is not overloaded in a collision.

Mercedes, BMW and Renault nowadays supply extremely soft pillows as a headrest, which feel just as comfortable as the luxurious pillow of your bed.

Sports cars are an extra challenge

The low seat in sports cars makes it extra difficult to sit properly.

AGR has a tip for this.

"Make sure you sit as high as possible. This not only gives you a better view, it is also good for the pelvic position, which is important for the curvature of the spine."
