Many buyers first consider the appearance when choosing a chair, but what really determines the repurchase rate and negative review rate are often three invisible details:

Lumbar support system: Static lumbar support has gradually been replaced by dynamically adjustable lumbar support with four-way adjustment. Products that can automatically adapt to changes in user sitting posture have a significantly higher positive rating in overseas e-commerce reviews.

Sponge density and process: High density cold foam (45kg/m ³ or more) can extend durability for 1-2 years without collapsing compared to ordinary sponges. The integrated foaming process avoids the problem of delamination odor caused by multi-layer bonding.

Chassis safety and smoothness: Explosion proof chassis with BIFMA or SGS testing and control levers with linear adjustment function are becoming standard for products in the mid to high price range.

Whether it is an esports chair or an office chair, the material level of these three core components basically determines the positioning and profit margin of the product in the target market.
