Office Chair Height Increasing Base Feet

There are various types and price ranges of office chair height increasing base feet available, and attention should be paid to size compatibility and performance points when making a purchase. Here is a detailed introduction:

I. Common Types and Prices

1. Desk Leg Height Increasing Base: These products are usually adjustable in design and suitable for heightening needs of various furniture such as desks, coffee tables, and sofa chairs. Their price is approximately ¥8.5, and they have comprehensive functions. However, it is necessary to check whether the adjustment range matches the size of the chair legs.
2. Plastic Adjustable Feet: Sold in bulk as ready stock, with common specifications of 40M818, suitable for scenarios such as tables and chairs and shelves. The price can be as low as ¥0.24, but it is necessary to confirm whether the screw diameter (e.g., M8) is compatible with the hole diameter of the chair legs.
3. Three-Wire Anti-Slip Thickened Adjustable Feet: Designed with 6-mm or 8-mm screws, emphasizing anti-slip and load-bearing performance, with a price of approximately ¥0.23. These products are suitable for scenarios requiring stable support, but it is necessary to measure the thickness of the bottom of the chair legs to choose the appropriate specification.
4. M6 Adjustable Feet: Designed specifically for stability, suitable for shelves, floor feet pads, etc., with a price of approximately ¥1.0. They have outstanding moisture resistance, but it should be noted that the M6 screw diameter may not be suitable for all chair legs.
5. Universal Adjustable Feet: Such as adjustable feet for furniture and office desks, with a price of approximately ¥0.3, emphasizing moisture resistance and moisture-proof functions, but it is necessary to check whether their size matches the contact surface at the bottom of the chair legs.
6. Large Disc Adjustable Foot Pads: Using 8*48 specification plastic accessories, with a price of approximately ¥0.2, suitable for scenarios requiring thickened support, but it is necessary to confirm whether their diameter covers the bottom of the chair legs.

II. Key Points for Purchase

1. Size Compatibility: It is necessary to accurately measure the diameter or hole diameter of the chair legs and choose the screw diameter (e.g., M6, M8) or the inner diameter of the adjustable feet that match to avoid looseness or inability to install.
2. Anti-Slip Performance: Prioritize products with rubber pads or textured designs at the bottom to prevent the chair from sliding, especially suitable for wooden floors or tiled floors.
3. Load-Bearing and Sturdiness: Choose materials (such as metal or thickened plastic) according to the weight of the chair to ensure no deformation during long-term use.
4. Seat Cushion Hardness: If the seat cushion of the chair is too soft, increasing the height may lead to instability of the center of gravity, and it is necessary to use a hard seat cushion or adjust the height increase.

III. Usage Precautions
Before installation, clean the debris at the bottom of the chair legs to ensure that the adjustable feet are flat and in close contact with the contact surface; regularly check whether the screws are loose to avoid the risk of falling off due to long-term use.
