I have to add my vote to timber. Glass, in my opinion, tend to leech spaces of warmth and with timber tables available to suit so many design styles and to suit a range of budgets, As Wild River Store rightly pointed out "Timber develops character" over time and so it begs the question why anyone would look further than timber?

Ive been researching for quite a while,,and Houzz photos have been a great resource.

It might be worth while to consider the rest of the space also. Your breakfast bar/kitchen is located quiet closely to your dining table so depending on your kitchen space (apologies, I can't see too much of your kitchen from the photo) you might want to think about the overall style you want to achieve for you entire open plan space, and select pendants that would work for both your kitchen and dining. This is a project I worked on recently that shows how two different types of pendants can work harmoniously in the one space that is most similar to your kitchen and dining set up. Keep us posted on what you decide!

Unfortunately there is no simple answer for the best dining table for your home as so much depends on your household, lifestyle, and dimensions of the available space. You need to think about who uses it, and how you entertain. If you have messy toddlers get something that is easy to keep clean, and is fairly robust. If you like to host large number of people for dinner maybe a table that can be extended. What is the size of your household? Do you usually eat at the breakfast bar? For materials and colours I would be looking at what you already have in your kitchen and family room as a starting point. Don't introduce new colours or new materials to the dining area that aren't already in the kitchen or family room. Your bar stools look good and work well with your kitchen. If you are happy with your bar stools I would use them as a starting point to see if you can source complementary dining chairs. Once you have sourced your dining chairs find a table that works with the chairs. Make sure that the dining chairs that you select are the right height for the table, and if you get dining chairs with arms (called carver chairs) that the arms fit under the table. The tops of tables are a fairly consistant height, but the clearance under the table depends on the materials, structure and the position of the table legs. The number of chairs that you can fit around a table will depend on the position of the table legs and the width of the dining chairs. Measure your available space carefully before looking at tables to ensure that you have adequate circulation space around the dining setting to access the external door. Make sure that there is enough room to get past a chair when somebody is sitting at it. Without knowing your household, or lifestyle, or the dimensions of the room I think a six person or possibly an eight person circular table would work well in the space, but this may not meet your needs (or fit). Best of luck with finding the best dining table, Dr Retro
