Need a durable comfortable ergonomic styled chair that will handle someone 6' to 6'4" and weight range of 300-400#. Most offerings will not handle someone of this size, either they do not sit well (don't fit the body and proportions) or do not hold up (busted within a month or two). The two chairs shown look quite like a decorating statement, but no way would they hold up to someone of perhaps taller than 5'10" and weighing more than 180#....

As Karthik has suggested above you have to use good quality anchor bolts as per the load specifications . If you want to be doubly sure use two anchor bolts so that the load is shared. You will need changes to the chain links for that. Thanks Nitin Cornerstone Designs Bangalore.

Hello dear, You can contact Oriental Creativity. Here you can get a good dining table set that can completely fit in your dining area. I bought a 6 seater dining table set from this shop at a very good range.

Hey Lauren, Can you share images of you home so that I can get a better idea of what chairs to suggest. There are way too many types of 'modern'! We can look for 19" chairs, or fit a one inch base, which you can easily find on amazon. Edit: Can you alter the legs of your trestle table to make it look modern? They are inherently very country.
