First, make sure that the bottom is flat. If the bottom is uneven, it is easy to cause the sofa cushion to run off. So it is necessary to turn the sofa over and check the bottom. If there are uneven places, you can fill them with boards.
Second, determine whether the sofa cushion is installed correctly. If the bottom is flat, but the mat will still run, you need to check whether it is installed correctly. There are usually additional devices behind the cushion, which can be fixed on the sofa. Make sure that the accessories are firmly installed on the sofa so that the cushion will not move.
Third, add anti-skid pads. The anti-skid pad can effectively prevent the seat cushion from sliding. These mats can be easily bought in Amazon or home stores. Put it on the sofa, and then put the cushion on the non-slip mat, so as to prevent the cushion from sliding.
Finally, consider replacing the seat cushion. If none of the above methods can solve the problem, then you need to consider replacing the cushion. Some cushions slide easily because of quality problems. If the cushion is too old or damaged, it needs to be replaced in time.
Therefore, the above method can solve the problem that the cushion will run off. Therefore, following these methods, you can avoid the sliding of the cushion and keep the sofa comfortable and safe.
