How to Assemble Your Chair

Before You Start

Are you hydrated? Loose? Limber? Assembly is easy and takes only 5 minutes, but it’s always good to be all of the above.

Remember to work on a soft, protective surface.

If you don’t have one available, you can lay out the cardboard inserts included in the box.

In your box you will find:

  • A

    5× Casters

  • B

    Star Base

  • C

    Gas Lift

  • D

    Seat Plate

  • E

    Seat Assembly

  • F

    4×¾″ Bolts

  • G

    Allen Key

+ You Also Need: Box cutter and/or scissors


Open your box. Pull out the Star Base (B), Seat Plate (D), and cardboard insert underneath and set them aside.


Use the finger tab to pull out the triangle-shaped corner insert with the top cover. Lay the insert flat on the ground and open to reveal the Casters (A), Gas Lift (C), ¾″ Bolts (F), and Allen Key (G).


With the Star Base (B) upside down, insert five Casters (A) firmly into the holes.


Take the remaining corner inserts out of the box. While holding the box, grab the frame of the chair and turn the box on its side. Pull the Seat Assembly (E) out so the bottom is facing up. Move the box aside.


Place the Seat Plate (D) squarely on top of the Seat Assembly (E), making sure the arrows on each face the same direction.


Attach Seat Plate (D) to the bottom of the Seat Assembly (E) by placing a ¾″ Bolts (F) through each hole of the Seat Plate (D) and using the Allen Key (G) to tighten the bolts completely so that the seat plate and assembly are secure.


Flip the Star Base (B) over and insert the Gas Lift (C) through the center hole of the Star Base (B) so that the narrowest part is at the top.


Holding the Star Base (B) and Gas Lift (C) together, place them upside down into the opening on the Seat Plate (D). Press down to ensure it is secure.


Hold the frame of the Seat Assembly (E) and carefully lift the chair to place it right side up.


Use a box cutter or scissors to remove the zip ties from the Seat Assembly (E). Pull the seat open. Taking caution to avoid pinching your fingers, push the back cushion into an upright position until you hear a “click-lock” sound confirmation.

That’s it!

Your new chair has a seat waiting for you.

How to Sit in Your Chair

In order to reap the benefits of your all33 chair, you must use it correctly.

First off, that means sitting all the way back in your chair, so that your butt makes contact with the lumbar support. The chair will then guide your spine into proper alignment and stack your vertebrae, allowing the weight of your head to be equally distributed by your back.

/01Working Those Abs

Our patented pivot technology engages your core to keep your energy levels high and blood pumping. To operate the pivot function, first sit back in your chair. Then push up from the floor with your toes until you feel the pivot rebalancing. You will instantly feel your core muscles engage. Do this anytime you want to strengthen your core, and challenge yourself each day to see how many crunches you can do!

/03Easing into Ergonomics

When using your all33 chair, it’s important to follow ergonomic guidelines for your entire workspace. What good is owning the healthiest chair if the rest of your workspace isn’t set up for success?

Set the height of your chair so that your feet are able to rest naturally on the floor (or on a footrest) and your elbows are at a 90 degree angle when using your keyboard and mouse.

/02Getting Used to Good Posture

When we get used to sitting with bad posture, our bodies need a period of readjustment. For the first couple of weeks using your chair, you’ll be engaging muscles you haven’t used in a long time (or ever!) and may experience soreness. But much like going to the gym or lifting weights, that short-term pain transforms itself into long-term gains.

Should you continue to experience back pain, or if you experience an increase in pain or other issues for a prolonged period of time, please consult a medical professional with regard to your specific condition.

/04Taking Movement Breaks

Frequent breaks are beneficial for your long-term health and will improve your productivity. Even taking just one minute to stretch and move for every 30 you work will go a long way toward improving circulation.

How to Adjust Your Chair


While seated, lean forward and reach under the right side of the chair to find the handle. Lift the handle and raise your body up slightly to allow the chair to rise to the desired height. Once the desired height is reached, release the handle to lock the chair in place. To lower the seat, lift the handle while seated and let gravity do its thing. The chair will descend until the handle is released or the chair reaches the lowest possible position.


First, make sure you are sitting all the way back in your chair. Your body will balance in the pivot of the chair. When you push up from the floor with your toes, the pivot will rebalance and you will instantly engage the muscles in your core. Do this anytime to strengthen your core and work your abs.

/03tilt TENSION

Reach under the front center of the chair, grasp the round knob, and turn it counterclockwise to stiffen the tilt mechanism for a heavier user. Turn the knob clockwise to loosen the tilt mechanism for a lighter user. Rotate the knob until the desired resistance is reached.


While seated, reach under the right side of the chair to find the height adjustment handle. Pull the handle all the way out (away from the seat plate) to allow the chair to tilt backwards. To stop the tilt mechanism, push height adjustment handle in toward the seat plate.


The chair has movable arms so they can be flipped up and down. Simply push the arms up next to the back cushion to roll your chair nearer to your desk.

Once you’ve found your sweet spot, you can push off with your feet to turn in your chair.

Chair Care & Cleaning


Proper care ensures your chair will last for years. Our modular design allows all components to be individually removed and replaced.

/01Vegan Leather

Use a slightly-dampened microfiber cloth. Simply sprinkle the cloth with a little water and wipe the vegan leather clean from dirt and light stains. Leave the chair to air dry.

Leather cleaning products work well on our vegan leather. Make sure to spot test the product on a small area before cleaning your chair completely. Spray a small amount onto a clean microfiber cloth and gently wipe clean.


Over time, it’s natural for fabric to trap loose particles and dirt. These can be easily removed with a vacuum. Clean any spills as soon as possible by blotting with a dry cloth or paper towel, taking care not to rub the stain into the fabric.

Stubborn spots may require the use of a fabric cleaner or stain remover. Spray a small amount onto a clean microfiber cloth, and clean according to the cleaner’s instructions.
