A chair comprising:
- a seat component comprising a seat portion with a bottom surface and a back support portion, the seat portion and the back support portion comprising a uniform body;
- an intermediate support component joined to the seat component and comprising a first plate and a second plate, the first plate being joined to the bottom surface of the seat portion, the second plate comprising a hole, the first plate and the second plate being spaced apart from each other using a first bellows, a second bellows, a third bellows, and a fourth bellows, and the first plate and the second plate being coupled together using a first rod, a second rod, a third rod, and a fourth rod, each of the first rod, the second rod, the third rod, and the fourth rod being at least partially contained within one of the first bellows, the second bellows, the third bellows, and the fourth bellows, a motion control mechanism that is selectively engagable with the first plate and that extends through the hole of the second plate;
- and
- a leg component comprising a first pair of legs and a second pair of legs, each of the first pair of legs and the second pair of legs being joined to the second plate.
A chair having a seat portion that is capable of selective wobbling relative to a leg portion, the seat portion being joined to a first plate and the leg portion being joined to a second plate, the first plate and the second plate being spaced apart by one or more resilient member, the first plate and the second plate having a range of motion that can be locked out by a motion control mechanism, and the motion control mechanism being positioned at least partially between the first plate and the second plate.
A chair having a seat portion that is capable of selective wobbling relative to a leg portion, the seat portion and the leg motion being joined by a means for controlling wobbling movement of the seat portion relative to the leg portion.
