Office Chair, Lifting Chair with Footrest

Information on office chairs, lifting chairs with footrests, and related accessories is as follows:

I. Office Chairs with Footrests

1. Chair NB237
   This model features a combination of an adjustable single chair and a footrest. The footrest part needs to be fixed to the footrest frame using a 4.2-centimeter hex socket screw, and attention should be paid to matching the screw specifications during installation. Its lifting function is usually achieved through a gas spring, and the footrest and chair body can be adjusted in height simultaneously, making it suitable for office scenarios requiring short breaks.

2. Sanwa Footrest Stool
   As an independently adjustable footrest stool, it is made of PU leather, which is easy to clean and wear-resistant on the surface. Functionally, it supports height adjustment and tilt angle adjustment (about 15 degrees), and is equipped with brake wheels for easy movement. The design conforms to ergonomics and can be used in conjunction with an office chair to relieve leg pressure, making it suitable for people who work in a seated position for long periods.

3. Aurora CELSQW0014 Office Chair
   This model is an office chair designed with ergonomics in mind, integrating a reclining function and a footrest module. The footrest is usually hidden under the chair body and can be extended to form a flat lying position in conjunction with the chair back, making it suitable for lunch breaks or short rests. The material is mostly breathable mesh fabric or leather, suitable for both home and office scenarios, but attention should be paid to the weight-bearing limit of the footrest.

II. Selection of Accessories for Lifting Chair Feet
Chair foot accessories on the market mainly fall into two categories:

1. Structural Types

   • Four-Star Feet: With a four-claw design, they offer moderate stability and are suitable for lightweight office chairs.
   • Five-Star Feet: With a five-claw distribution, they have stronger weight-bearing capacity and are commonly found in mid-to-high-end office chairs, providing smoother movement when paired with casters.

2. Materials and Prices

   • Stainless Steel Chair Feet: Highly corrosion-resistant, suitable for humid environments, and relatively expensive (about 150-265 yuan).
   • Aluminum Alloy Chair Feet: Lightweight and strong, with moderate cost-effectiveness (about 80-180 yuan).
   • Nylon/Plastic Chair Feet: Low cost (19-50 yuan), but with weaker weight-bearing capacity and durability, suitable for temporary use scenarios.

III. Purchase Recommendations
For an overall solution, prioritize choosing office chairs with footrests (such as NB237 or Aurora models); if upgrading an existing chair, consider purchasing a Sanwa footrest stool separately as a supplement. When selecting chair foot accessories, consider the weight of the chair, frequency of use, and budget. Five-star aluminum alloy feet are a common choice that balances performance and cost. During installation, follow the instructions strictly to ensure that the screws are tightened to avoid safety hazards.
