Office Chair Height Increasing Wheels

Office chair height increasing wheels can be achieved through specialized fixers or adjustable accessories, and it is necessary to choose suitable products according to functional requirements. Here are specific solutions and purchasing suggestions:

1. Integrated Height Increasing and Fixing Solution: Chair Caster Fixers
These products achieve height increasing through non-slip and wear-resistant bases, while also being equipped with locking mechanisms to fix the wheels. For example, some fixers feature a thickened metal base design that can raise the chair height by 5-8 centimeters. The rubber pads at the bottom enhance friction to prevent sliding, and the top snap-fit structure can accommodate conventional wheels with diameters of 40-60mm. This solution is suitable for scenarios where both the issues of the chair being too low and sliding need to be addressed, such as in hard-surface office environments.

2. Pure Height Increasing Solution: Adjustable Furniture Accessories
The 1688 platform offers a variety of pure height increasing accessories, with height adjustment as their core function:

• Metal Adjustable Cabinet Legs: These legs achieve height adjustment from 3-10 centimeters through threaded rods and come with 360° rotating casters at the bottom. They are suitable for heavy furniture such as filing cabinets, but it is necessary to confirm the load-bearing range (usually marked as 50-200kg).
• Threaded Rod Casters: These casters use M8/M10 standard threaded interfaces, with a height adjustment precision of 1mm and a single-caster load capacity of up to 80kg, suitable for scenarios requiring fine height adjustments.
  For such products, it is important to ensure that they match the diameter of the original chair's wheel axles. For example, if the original wheels have an M8 thread, corresponding accessories should be selected.

3. Mobile and Fixed Switching Solution: Casters with Locking Function
The 60mm/65mm casters mentioned in the video solution have dual functions:

• Mobile Mode: The soft PU-wrapped wheel body, combined with a silent sleeve, can reduce rolling noise by 60%, suitable for carpets or wooden floors.
• Fixed Mode: The wheels can be locked through a foot pedal or manual switch, with a post-braking deviation of less than 2mm, meeting the needs of scenarios requiring temporary fixing (such as drawing or typing).
  When purchasing, it is necessary to measure the diameter of the original wheels (it is recommended to use a vernier caliper to measure the widest part of the wheel body) and the length of the wheel axles to ensure that the new wheels can completely cover the original mounting holes.

Core Purchasing Principles:

• Functional Priority: If a fixing function is required, prioritize choosing casters with locking mechanisms; if only height increasing is needed, adjustable cabinet legs are more cost-effective.
• Size Matching: The diameter error of the wheels should be controlled within ±2mm, and the length of the wheel axles should completely cover the original mounting positions.
• Load-Bearing Verification: The load capacity of a single caster should be greater than (the self-weight of the chair + the weight of the user) ÷ 5. For example, a 70kg user should choose casters with a load capacity of at least 35kg each.

It is recommended to purchase through formal e-commerce platforms first and request merchants to provide size measurement diagrams and load-bearing test reports to avoid the risk of chair tipping due to mismatched accessories.
