I am experiencing poor cushion quality because whenever I sit in the chair, I feel as if I am sitting on a hard surface after just a few seconds.

There is also the same problem with the side handles as there is absolutely no cushion cover at all.

Fabric is really hard and I can't even sit for a minimum of 15 minutes on this chair and I am extremely dissatisfied with the quality of this chair and I want to immediately return it, so please let me know the process for doing that.
