Hi JB,
[quote]I see there are a few topics going about tuft and needle right now. I just received a replacement mattress as the original wasn’t breaking in correctly, I guess… At least this is what I was told when I described the situation. Anyway, I was wondering how everyone likes the newer model. However, I’m not reading a lot of positive comments.
I believe the original mattress, for me, was just too firm.[/quote]
I would tend to agree that it was probably just too firm for you rather than being an issue of breaking in.
Thanks for your feedback on their new design and how it compares to the old one as well … I appreciate it 
You can see my comments about it in this topic which seems to fit your experience.
