IKEA Office Chair Modification

The modification of IKEA office chairs should be selected based on the specific model. Currently, only the Poäng chair has a clear case of users spontaneously adding wheels. For other models, it is recommended to refer to the official installation instructions or contact after-sales service to confirm compatibility.

Specific Steps for Adding Wheels to the Poäng Chair

Users of the Poäng chair have solved the problem of the robot vacuum cleaner getting stuck by adding idle casters, while also increasing the chair's height and mobility. The modification steps are as follows:

1. Tool Preparation: You will need an electric drill, casters (it is recommended to choose universal casters with fixing screws), and a tape measure (for locating drilling points).
2. Material Confirmation: The legs of the Poäng chair are made of particleboard. Ensure that you avoid internal structures when drilling to prevent cracking.
3. Drilling and Fixing: Mark four points symmetrically at the bottom center of the chair legs (adjust the spacing according to the size of the casters). After drilling with an electric drill, screw in the caster screws to fix them.
4. Effect Verification: After modification, the chair's height increases by a few centimeters, the robot vacuum cleaner can bypass it, and the resistance during movement is significantly reduced. Precautions: When drilling particleboard, control the rotation speed to avoid high temperatures causing edge charring; the load-bearing capacity of the casters should match the weight of the chair (it is recommended that each caster has a load-bearing capacity of ≥50kg).

Installation and Modification Suggestions for Other Models

1. Tofias Chair: The official provides a standard installation process. Assemble the metal bracket, gaskets, and screws in order, and finally fix them with an Allen wrench. The bottom comes with anti-slip pads, and no additional wheels or accessories are required.
2. Alefjäll Office Chair: Users report that two people can assemble two chairs in one hour. The design focuses on home style adaptability, but no modification cases have been mentioned. It is recommended to install according to the instructions first.
3. MARKUS Markus Chair: The design includes adjustable tilt tension, headrest/armrest accessories, and casters suitable for various floors such as wooden and tiled floors. There are no user modification records, and forced installation may damage the original structure.

General Modification Principles

If you need to modify other models, you should first contact IKEA's official to confirm structural compatibility, focusing on verifying the following:

• Whether the chair leg material is suitable for drilling (e.g., solid wood and metal require special tools);
• The original caster type (e.g., changing from fixed casters to universal casters requires replacing the bracket);
• Whether the modification affects stability (e.g., raising the height may cause the center of gravity to shift). Risk Warning: Non-official modifications may violate the warranty terms. It is recommended to prioritize using the chair's original adjustable functions (such as the tilt tension adjustment of the MARKUS chair) to optimize the user experience.
