For dining section we have all tables divided in 3 major groups. casual style tables (for everyday use), counter-height tables (higher, bar style seating, for everyday use) and family size dining. Latter ones usually tend to seat 6 or more persons and usually have servers/buffets or other dining units, like Chinas or Vetrinas.
We also have a separate dining chairs section, but in most cases we don't add chairs there (when there is no distinct picture) - but you can usually purchase all types of chairs by browsing 3 main groups above - just check those options. Same applies to buffets, kitchen cabinets, etc. Chairs, in most cases, can be purchased by quantities of 2 or 4.
