Our driving force here at Designer Cognoscenti - "Comfort is King"
There's a reason Eames is famous for their furniture designs and maintains it's value over decades, yes it has simple "Less is more" Design but the most important thing is the furniture has deep comfort, well thought out ergonomic designs.
Pacific Green's Bruce Dowse of Australia, Roche Bobois from France, Ekornes from Norway, Many Danish Designers and many older American Manufacturers.
Comfort brings a long term human benefit to be deeply rejuvenating in your own home. Some furniture just holds you up off the floor but finely tuned designs cradle the human skeletal system for recharging your batteries.
The true test of a classic design is when it's still being manufactured after more than a half century after being introduced.
