You probably need to talk to your local bike shop.
Yes, they are pretty firm seats, but for a reason.
The one you are talking about may be entirely the wrong size, like mentioned just above around the sit bones. If the seat is the correct size for you and you feel it is too stiff, it's likely something you will adapt to.
Again, anything softer will be pushed up into your body. Note the new style seats have a groove. That groove is meant to allow our bodies to rest on the sit bones and be supported by the seat, making our body parts not have pressure applied to sensitive nerves. If you are experiencing any numbing sensations, the seat is probably front for you. If you consider seats have the groovet to relieve pressure, think what is going to happen when you sit on a sponge. All tha extra material has to be forced someplace....and it will go where the voids are.
Spend a few minutes searching the internet for proper saddle fit....the diagrams may be helpful instead of our words.
Again though, it may be the seat on your bicycle is the absolute wrong one for you. That is not for the internet to decide because we can't see you sitting on it. My 2000 MTB came with a relieve in the seat....as did my 2016 and 2019 bicycles. I have not had to change them but I a pretty averaged body type per stereotypical MTB person. I purchased a used road bike, 2006 model and it did not have a relieve. I rode about 2 rides on that and had to chagne the seat because it was causing way too much pain and numbing. That was only my 2nd ever seat, the 2006 mountain bike then this used road bike. I had very little experience but did know the reason for the relief. I purchaesd a seat, quite firm, that very similarly matched the dimensions of my MTB seat and it was like night and day because of the relief. The comparison saddles were all very similar actually, the 2006 sadde, the 2000 MTB and the new one I purchased for the road bike. It was the design that made a difference, not the amount of extra or missing padding.
The type of shorts you ride in may also be a factor. I am fortunate enough to be comfortable riding in board shorts (hybrid to be exact) and never required a chamois. You may need to consider a proper pair of bottoms to ride in as well.
This video may explain. You don't need that saddle but you can understand the theory of saddle fit.
