Office Chair Accessories Inclusion

Whether an office chair comes with accessories depends on the specific brand, model, and merchant policy. Some products include basic accessories, while others require separate purchases.

1. Some office chairs include basic installation accessories
   According to market cases, some brands provide necessary accessories for installation when selling their products. For example, the installation instructions for the Deli KF270 ergonomic chair and the NetEase Yanxuan Xiaomanyao S9Lady ergonomic chair explicitly state that the products come with basic components such as a five-star base, wheels, gas lift, and screws. These accessories are typically used for basic assembly of the chair, allowing consumers to complete the installation without additional purchases. However, it should be noted that the range of included accessories may be limited to components directly involved in structural connections, while decorative accessories or upgrade components (such as adjustable headrests and lumbar supports) may need to be purchased separately.

2. Some accessories need to be purchased separately based on needs
   There is a large number of office chair accessories sold separately on the market, including five-star bases, trays, gas lifts, chassis, armrests, and wheels. The uses of these accessories fall into two categories: one is to replace damaged original components (such as a leaking gas lift or worn wheels), and the other is to upgrade functions (such as replacing with a more durable five-star base or adding adjustable armrests). However, the reference information does not clearly state whether such accessories are included with the chair, and consumers usually need to consult the merchant or make purchases on their own according to their needs. For example, if the chair originally comes with fixed armrests and the user wants to upgrade to adjustable armrests, they need to purchase the corresponding accessories separately.

3. Merchant policy is the key criterion for judgment
   Whether accessories are included ultimately depends on the merchant's sales strategy. Some brands may include accessories as "standard configurations" in the selling price, while others may offer choices in the form of "basic model + accessory package". It is recommended that consumers confirm the list of accessories through the product details page, customer service consultation, or user reviews before making a purchase to avoid installation difficulties due to missing key components. For example, if the chair does not come with a gas lift, when purchasing separately, attention should be paid to selecting a model that matches the chair's load-bearing capacity and height to ensure safety and compatibility.
