It's an extremely personal choice. Bodies are different. The following are somewhat pricey options. In my opinion the Knoll Regeneration is pretty good. Hermann Miller chairs are also good, but the Aeron is probably the least ergonomic thing they sell now – and definitely not "minimal". The Setu might fit your criteria.
