Driver’s seat

Hello together, since recently the driver’s seat of my V60 II as if you are sitting on an old sofa. The snoring comes from the rear part of the right cheek of the seat and from the lower part of the right cheek of the seatrest. The snaring is particularly penetrating at left turns as well as on uneven roads. My car has the textile/T-Tech cushion, is just over three years old and has about 46,000 km on the tacho. Has any of you heard of such experiences or of such a possible solution? Thank you in advance for your support and many greetings, Heili74
