In English, this is known as a Gel Seat Cushion or a Gel Seat Pad. ​Here is a quick guide to what it is and why people use it: ​What is a Gel Seat Cushion? ​It is a portable cushion made from a specialized, flexible gel material (often medical-grade silicone or TPE). Most of these cushions feature a "honeycomb" or "grid" design, which allows the gel to compress and distribute weight effectively. ​Why is it used? ​Pressure Relief: It is designed to take the pressure off your tailbone (coccyx), hips, and lower back. This is especially helpful if you sit on a hard chair for a long time. ​Cooling Effect: Unlike foam cushions that trap heat, the gel material and the open-grid design allow air to circulate, keeping you cool and preventing sweating. ​Durability: The gel is highly resilient, meaning it won't "bottom out" or lose its shape over time like a standard sponge or foam pillow. ​Posture Support: It helps maintain a more comfortable and natural sitting position, reducing fatigue during long shifts. ​Who is it for? ​Office Workers & Cashiers: Anyone who spends several hours a day sitting at a desk or a workstation. ​Drivers: It is very popular for car seats to make long commutes more comfortable. ​Frequent Travelers: People take them on long flights or bus rides to soften hard seats. ​Features to Look For: ​Non-Slip Bottom: Most come with a washable fabric cover that has a "grippy" bottom so the cushion doesn't slide off the chair. ​Portability: They are usually lightweight and have a handle, making them easy to carry from your car to your office. ​Since you are working as an accountant and cashier, using one of these on your office chair can significantly reduce the physical strain on your back by the end of the day
