Contoured seat cushion for office and car

Sitting on a hard chair for hours—and by the end of the day, you feel every inch of it.

Anyone who spends many hours at a desk every day or takes long drives knows the feeling: The seat puts pressure on you, your legs become heavy, and you constantly slide forward. The Lumbox seat cushion addresses this with a contoured double curve that deliberately shifts weight onto the thighs, along with a shaped coccyx cutout that relieves pressure at a critical point. The result: You sit more comfortably and upright and get up from your chair feeling more balanced at the end of the day.

Benefits

• No more constant readjusting: The contoured double curve along the front edge follows the natural shape of the thighs, so you do not slide out of position or have to keep shifting, and you do not lose concentration because of uncomfortable seating.
• The cushion lasts all day without needing to be replaced: The 5.6 cm-thick foam core does not compress after hours of sitting, so you are not already sitting on a flat cushion by midday and forced to start over.
• No more guessing about fit and stability: Measuring 40 cm wide and 37 cm long, the cushion fits most standard chairs, while the flat underside stays securely in place on smooth surfaces—no slipping and no readjusting.

How to Use

1. Place: Place the cushion centrally on the chair or car seat with the flat side facing down—the shaped indentation should face backward.
2. Adjust: Sit so that the coccyx cutout is directly beneath your tailbone and the front edge is flush with the edge of the chair.
3. Use: Adjust the position slightly if needed—the cushion remains stable thanks to its flat underside and does not need to be secured during normal use.

Pro tip: When using the cushion in a car, push it all the way back against the backrest. This allows you to benefit especially from the weight distribution onto the thighs, which makes a real difference on long drives.
