I have been looking for a chair similar to the H&M Author Chair, with the rounded tufted back, for quite a while.

So when one of our not so local dealers said he would order one for his showroom for us to try I was very excited. Six months later he finally calls and says it's in. We drove to the showroom yesterday, and I have to say this is one BEAUTIFUL looking chair in the Weston Cane Burnished leather. The problem was that the tufted back was so stiff, it felt lumpy and my back hurt after sitting in it for a while. I have had lower back pains for the last couple years and that was why I was specifically looking for this type of chair was for the support. I've sat in similar chairs in the past and if they actually fit me (I'm 6'2") they can be the most comfortable chair.

So my question is to anyone who has an Author chair or similar tufted back chairs or couches, will the tufted back soften up much over time?
The dealer said probbaly not, but he wasn't very knowledgeable.
