Abstract
A chair has a metal base, a matrix of metal tubes having a common outside and an inside diameter, welded orthogonal to the metal base, extending vertically, and a matrix of posts matching the matrix of metal tubes, the posts bored for a portion of a length of each post, with each post engaged over one of the metal tubes. The chair is characterized in that one row of posts along one edge of the metal base comprises posts of a height greater than other posts, and forms a backrest for the chair, and in that the remaining matrix of posts, of a lesser height than the posts forming the backrest, are of a common height, and form a seat surface for the chair.

A chair, comprising:
- a metal base;
- a matrix of metal tubes having a common outside and an inside diameter, welded orthogonal to the metal base, extending vertically;
- and a matrix of posts matching the matrix of metal tubes, the posts bored for a portion of a length of each post, with each post engaged over one of the metal tubes;
- characterized in that one row of posts in the matrix of posts along one edge of the metal base comprises posts of a first height and forms a backrest for the chair, and in that a remaining matrix of posts of the matrix of posts, of a second height less than the posts forming the backrest, forms a seat surface of the chair, the remaining matrix of posts forming the seat surface of the chair are compound posts having an upper portion engaging the outside diameter of the tubes, the upper portion supported on a compression spring such that the upper portions of posts in the remaining matrix of posts provide a resilient surface for a subject seated on the chair and the upper portions supported by the compression springs are all in the remaining matrix of posts in positions other than a position forming an edge of the matrix.
