Lots of information about Morris chairs, also
some good links to suppliers of materials. And
he has some hardware of his own that he has made
incidental to his own chair-making business but
is willing to sell to others.

I do some part-time upholstering and, surprisingly, I've worked on several Morris chairs. In that link, notice the height of the legs compared to the height of the arms above the seat frame. The seat cushion thickness needs to be appropriate, in order for the arms not to be (feel) so high. If the seat cushion is too low, one's arms feel awkward, i.e., too high, when resting on the chair's arms.

Also, I've worker on a Morris chair (variation) with a caned backrest.... I re-caned the backrest. The seat depth, for the caned chair, was shorter, than for a typical chair with a cushioned (3" or 4" thick) backrest. At first glance, a caned chair frame, without the seat cushion installed, looks mis-proportioned and one thinks something is wrong with it.... until you realize why the seat depth needs to be shorter. *For the caned chair I worked on, the customer still wanted a removable thin (2") backrest cushion.
