The Diffrient World chair is the simplest, most sustainable and most user-friendly high-performance task chair. Utilizing a virtual mechanism, the sitter’s body weight and the laws of physics, the chair automatically adapts to each user to provide perfect resistance and support through the full range of recline. Its Form-Sensing Mesh Technology also provides perfect lumbar support for every user. Weighing only 25 pounds and featuring far fewer parts—just 80 overall—than traditional task chairs, the Diffrient World chair promises a long, serviceable life with an industry-best 15-year 24/7 warranty. Disassembly is also a cinch to encourage recycling 99% of its content.
