Safety Information

• This chair has a maximum weight capacity of 400 lbs. Do not exceed this limit.
• Improper use of adjustable components or heavy-duty casters may result in injury.
• Always follow assembly instructions carefully, even for pre-assembled components.
• Use caution when operating adjustable features to prevent pinching or sudden movements.
• Ensure all bolts and screws are securely tightened before use and periodically check for looseness.

Setup

The SertaPedic Emerson Task Chair is designed for minimal setup, often arriving largely pre-assembled. Follow these general steps to prepare your chair for use:

1. Unpack Components: Carefully remove all parts from the packaging. Retain packaging materials until you are satisfied with the product.
2. Inspect for Damage: Before proceeding, inspect all components for any signs of shipping damage. Contact customer support immediately if any damage is found.
3. Caster Installation (if separate): If the casters (wheels) are not pre-installed, firmly push each caster stem into the holes at the end of the chair base until they click into place.
4. Gas Lift Insertion (if separate): Insert the larger end of the gas lift cylinder into the center hole of the chair base.
5. Seat Placement: Carefully place the assembled seat onto the top of the gas lift cylinder. Apply gentle downward pressure to secure it.
6. Final Check: Ensure all connections are secure and the chair is stable before sitting.

Operating Instructions

Your SertaPedic Emerson Task Chair features several adjustment mechanisms to optimize your comfort and support:

1. Seat Height Adjustment

• To Raise: While standing, pull the lever located on the right side of the seat upwards. The seat will rise automatically. Release the lever at the desired height.
• To Lower: While seated, pull the lever located on the right side of the seat upwards. The seat will lower under your weight. Release the lever at the desired height.

2. Tilt Lock-Out Adjustment

This feature allows you to recline the chair and lock it in a tilted position, or keep it upright.

• To Recline: Pull the lever on the left side of the seat outwards. Lean back to the desired angle.
• To Lock Upright: Push the lever on the left side of the seat inwards. The chair will return to its upright position and lock.

3. Arm Height and Width Adjustment

The arms are designed to be height and width adjustable for custom comfort.

• Arm Height: Locate the button or lever on the side of each armrest support. Press and hold this mechanism while simultaneously raising or lowering the armrest to your preferred height. Release the button/lever to lock.
• Arm Width: Depending on the model, arm width adjustment may involve loosening a knob or bolt underneath the seat or on the arm support, sliding the armrest in or out, and then re-tightening. Refer to visual guides if available for precise location.

Maintenance

Proper care will extend the life and appearance of your SertaPedic Emerson Task Chair:

• Cleaning: The premium bonded leather upholstery should be spot cleaned only. Use a soft, damp cloth with a mild soap solution for spills. Avoid harsh chemicals or abrasive cleaners, which can damage the material.
• Regular Inspection: Periodically check all bolts, screws, and connections to ensure they are tight. Re-tighten as necessary to maintain stability and safety.
• Caster Care: Keep casters free of hair and debris to ensure smooth movement.
• Avoid Direct Sunlight: Prolonged exposure to direct sunlight can cause the bonded leather to fade or crack.

Troubleshooting

If you encounter any issues with your chair, consider the following common solutions:

• Chair Squeaks: Ensure all bolts are tightened. A small amount of silicone spray on moving metal parts (like the tilt mechanism or gas lift connection points) can often resolve squeaks.
• Difficulty Adjusting Height: Check if the gas lift lever is fully engaged. If the chair is new, the gas lift may need a few uses to operate smoothly. Ensure no obstructions are preventing movement.
• Chair Feels Unstable: Verify that all casters are fully inserted into the base and that the chair base is level. Re-tighten all assembly bolts.
• Casters Not Rolling Smoothly: Remove any hair, dust, or debris that may be caught in the caster wheels.

If these steps do not resolve the issue, please contact Serta customer support for further assistance.
