You don’t see too many seriously comfortable wooden chairs. For starters, forget the soft bum-surface, the least I could use is an adjustable backrest. The RJR Chair by Mario Alessiani has a simple design feature that makes other wooden chairs feel like sitting on boulders. The RJR chair sports a backrest that can be angle adjusted by just twisting it. The RJR chair masks its awesomeness in a simple design that is sure to surprise you. Aside from the backrest, the RJR chair is stackable, and the greatest thing about the design is that it’s open source! The design plan is available to any carpenter or hobbyist who wishes to build the RJR chair. Just head down to the for more details! Designer:
