Office Chair Wheel Fixation
There are several main methods for fixing the wheels of an office chair:
Use chair fixed feet Fixed feet are installed by directly replacing the original wheels or adding them to the bottom of the chair legs. Their core advantage is strong stability. After installation, the chair can hardly move, making them suitable for scenarios that require long-term fixed positions, such as laboratories and drawing workbenches. However, the drawback is that when moving, the fixed feet need to be completely removed or the chair needs to be lifted, resulting in relatively low operational convenience. Therefore, they are more suitable for people whose stability requirements far outweigh their mobility needs.
Choose wheels with braking functions Brake wheels come in two types: one is the manual brake pad wheel, which is locked by pressing or flicking the brake pad on the side of the wheel; the other is the sit-brake wheel, which uses the weight of the human body to trigger the locking mechanism, locking when sitting down and unlocking when getting up. The advantage of these wheels is that they can flexibly switch between fixed and mobile states. However, multiple wheels (usually five) need to be operated simultaneously to ensure complete fixation, making the operation a bit cumbersome. They are suitable for scenarios that require frequent position adjustments but occasional fixation.
Use gravity self-locking wheels Gravity self-locking wheels achieve automatic locking through built-in springs or gravity sensing devices: when a person sits on the chair, the wheels lock automatically due to pressure; when the person gets up and the pressure disappears, the wheels return to a slidable state. These wheels combine fixation effects with operational convenience, automatically switching states without additional operations. However, it should be noted that their locking force may be affected by body weight, and people with very light weights may not be able to trigger complete locking.
Use chair wheel fixers Wheel fixers restrict wheel rotation through physical barriers. Common materials include PVC soft soles and nylon felt. The PVC type increases friction through soft materials, while the nylon felt type achieves fixation through fiber friction. Both have the characteristics of easy installation (just snap them on) and no damage to the floor. However, it should be noted that the fixers may become loose due to long-term use or mismatched wheel sizes, requiring regular inspection and adjustment.
Lay rough carpets under the chair Indirect fixation is achieved by increasing the friction between the wheels and the ground, suitable for scenarios with low fixation requirements (such as temporary office areas). This method does not require modifying the chair, but the fixation effect is greatly affected by the material and thickness of the carpet. Moreover, the carpet may shift due to wheel rolling, so it needs to be used in combination with other fixation methods.
