I have not purchased them myself. I think the style would lend itself to a traditional room nicely. As for the quality, here is what the site states:

With sturdy frames, unrelenting style and soft, resilient cushions, you will enjoy the comfort and stunning appeal of these chairs for years to come. Quality crafted for years of lasting use.

Pretty vague....
Good quality furniture usually has screwed and glued hardwood frames, has corner blocks, and the foam density of the seat starts at 1.8. Since HDC is not shouting out these qualities it's probably a nice looking chair that should hold up OK with light to medium use.

May be worth an email to them for further info on construction. I didn't see fabric content either. That may be a factor in quality also.

Here is a fairly short tutorial on the basics.

Hope that helps!
