This is an overview of how I created the diamond grid for the viking helmet...this might work for furniture as well..or maybe not :P Copy the base helmet mesh into a new layer, select the points you want and Chamfer them until you like the size of the squares. Select the newly created squares, give them a new surface name and subdivide the polygons using Faceted method . This will give us the edges we need later on. Bevel the N-gons just a little bit and then collapse the polygons. Select all the center edges that form a cross and bevel the edges until they roughly match the size of the squares. Merge Points , change the distance setting until you delete all the extra polygons and then delete all the 2-point vertices. Select the triangles with the surface name you applied earlier on and merge them into quads. Select all the quads (4-point polygons) and copy into a new layer. If you're not concerned with the heavy polygon count, you can subdivide the polygons ( F...
