Office Chair Simple Base

Office chair simple bases mainly come in two types: ordinary bases (fixed type) and single-reclining bases (ordinary reclining bases).

Ordinary Base (Fixed Type)

The ordinary base features a flat plate structure and typically does not come with adjustment handles or other mechanical control components. Its core function is to maintain the chair in a fixed position, with rigid connections between the backrest and the seat cushion, preventing angle adjustments. This design means the chair cannot recline, requiring users to maintain an upright sitting posture throughout use. In terms of applicable scenarios, ordinary bases are commonly found in lower-priced office chair products, such as bow chairs, four-legged chairs, or extremely low-priced swivel chairs. These chairs are typically used in environments with lower functional requirements, such as temporary office areas, meeting rooms, or simple home workspaces. Their advantages lie in their simple structure and low cost, but they lack ergonomic adjustment features, potentially increasing the risk of lower back fatigue with prolonged use.

Single-Reclining Base (Ordinary Reclining Base)

The single-reclining base incorporates a simple reclining mechanism in its structure, featuring a small lever or knob on the side of the base that allows users to adjust the backrest's recline. The recline angle is typically limited to a range of 20° to 30° and does not include an angle-locking function—when the user releases the control component, the backrest automatically returns to its initial position. This design is suitable for scenarios requiring brief recline for relaxation, such as basic employee chairs or home computer chairs. From a functional limitation perspective, single-reclining bases cannot meet users' needs for fixed recline angles, such as when reading or resting in a specific posture. However, their advantages include moderate cost and the ability to provide basic recline functionality, making them suitable for users with limited budgets who still wish to enhance some level of comfort.

The core differences between the two simple bases lie in functional complexity and applicable scenarios: ordinary bases prioritize fixed postures and are suitable for cost-sensitive scenarios; single-reclining bases balance functionality and cost through a simple reclining mechanism, suitable for basic office needs. Users should weigh their usage frequency, budget, and ergonomic requirements when making a selection.
