Equation Ergonomic Chair
Starting at $ 995.00 CAD
The Equation Chair pairs adaptive ergonomics with a sleek, tone-on-tone design for personalized comfort and a cohesive workspace look.
Tone-on-Tone
Each chair has been thoughtfully crafted to create a seamless synergy between fabric and mesh, offered in two distinct design identities.
Cozy & Timeless — Marble, Granite
An ultra-soft, solid fabric with a protective finish, paired with a new mesh that mimics the texture of a woven textile—almost like a micro-bouclé—for a refined, tactile experience.
Bold & Modern — Cobalt, Emerald, Onyx, Bronze, Terracotta
A premium woven seat fabric in rich, contemporary hues complemented by a durable, subtle two-tone elastomeric performance mesh. This pairing delivers modern expression and long-lasting performance.
Each variant is available in two frame options with matching caster wheels: Ash (off-white) or Black.
Bold and Intuitive Design
From its sculpted profile to its intuitive, weight-activated mechanics, the Equation Chair seamlessly unites design and comfort.
Equation’s proprietary back support system provides maximum comfort with minimal adjustments. The chair offers three precise backrest angles—103.5° (neutral), 105.25° (position 1), and 106.25° (position 2)— easily adjustable through the discreet buttons on the lower back frame. Dial the backrest recline and the seat depth for the perfect sitting posture.
The weight-activated tilt mechanism automatically adjusts to your body weight, delivering a smooth, personalized recline without manual tension knobs. It intuitively adapts to each user’s torque requirements, ensuring effortless comfort throughout the day.
An integrated seat slider enables easy, fluid seat-depth adjustment, helping you find optimal leg and lower-back support with just a simple motion.
Each chair comes standard with height-adjustable arms, giving you the flexibility to customize upper-body support—whether you’re typing, taking calls, or settling into long stretches of focused work.
For enhanced flexibility, optional dual pivoting arms allow for additional width and angle adjustments—perfect for users who need more dynamic arm positioning throughout the day.

FAQ
What's the Difference Between the YouToo & Equation Chairs?
The new Equation Chair brings together a weight-activated mechanism, an integrated seat slider, height-adjustable arms, and a backrest that adjusts forward and back. Optional dual-pivoting arms are also available for added flexibility. It comes in seven refined tone-on-tone color options.
The YouToo Chair offers height-adjustable arms, a reclining backrest with a lockable tilt, lumbar support with tension adjustment, and an optional back-height adjustment add-on. It also comes in a lower-seat option—the Small YouToo—designed for smaller frames, which includes a built-in seat slider. The regular YouToo can also be upgraded with a seat slider as an add-on and is available in 22 color combinations, including leather.
All Ergonofis chairs are designed with long-term ergonomics in mind and come equipped with dual-surface caster wheels that glide smoothly on both carpet and hardwood floors.
Are the Arms Of the Equation Chair Adjustable in Width?
The standard arms on the Equation Chair adjust in height only.
For more flexibility, you can upgrade to Dual Pivoting Arms, which allow the armrests to move freely—forward, backward, or diagonally on either side.
Is the Equation Ergonomic Chair Hard to Install?
Not at all—it's quick and straightforward. Every chair comes with a step-by-step installation guide, and assembly typically takes less than 10 minutes. The chair arrives in four main pieces: the base, gas cylinder, seat, and backrest. Just slide the gas cylinder into the base, then attach the backrest to the seat using the four included screws, and you’re done.
I'm in the US. Will I Need to Pay Any Tariffs or Customs Before Receiving My Chair?
You will never have to pay extra border taxes or fees. We never pass tariffs or unexpected fees on to our customers—what you see at checkout is exactly what you’ll pay. No additional duties, handling charges, or surprise costs upon delivery.
What's Your Return Policy?
We’re confident you’ll love your Equation Chair, which is why we offer a 30-day return window from the ship date if it doesn’t meet your expectations.
Are There Any Shipping Fees?
All of our chairs ship free, and any order over $150 also qualifies for free shipping.
