Office Chair Leather - Cheers

Cheers' leather office chairs, represented by the first-class series, are of reliable quality. When purchasing, it is necessary to comprehensively consider five dimensions: leather material, frame structure, electric module (if applicable), filling material, and detailed craftsmanship.

1. Leather Material
   Cheers' leather office chairs usually use top-grain cowhide, with core characteristics of natural texture and clear rebound wrinkles after pressing. It is recommended that the thickness of high-quality top-grain leather be ≥1.2mm, with an oily feel and toughness. It can be judged by touch: genuine leather is soft and elastic, and the wrinkles recover quickly after pressing; inferior leather or artificial leather feels stiff and has slow wrinkle recovery. In addition, there may be slight flaws on the surface of top-grain leather (such as natural textures or growth lines), which are normal phenomena and are actually signs of genuine leather.

2. Frame Structure
   The frame is the core structure that supports the chair body, and it is necessary to focus on the material and craftsmanship:

• Metal Skeleton: Give priority to thickened cold-rolled steel materials. The welding points should be smooth without burrs or false welding to avoid the risk of breakage after long-term use;
• Solid Wood Part: Use multi-layer boards or beech load-bearing structures instead of pine or fiberboard splicing. The former has stronger load-bearing capacity and is less likely to deform;
• Stability Test: When shaking the chair body, there should be no abnormal noise between the base and the seat frame, indicating that the structure is tightly connected and has no looseness hazards.

3. Electric Module (if applicable)
   If the office chair has electric functions (such as lifting, reclining, and leg rest linkage), it is necessary to focus on testing:

• Synchronization: When operating, all components should run synchronously without delay or stuttering;
• Noise Control: The motor noise should be lower than 50 decibels (close to the level of a quiet environment) to avoid interfering with work;
• Durability: Operate repeatedly more than 10 times and observe whether the motor heats up abnormally or fails in function to ensure long-term use stability.

4. Filling Material
   The filling material directly affects the comfort and support of the sitting feeling:

• Ideal Combination: High-density rebound sponge + independent pocket springs. The former provides a moderately soft and hard sitting feeling, and the latter enhances the support for the buttocks and waist, making it less likely to collapse after sitting for a long time;
• Density Test: Press the edge of the seat cushion. The faster the rebound speed, the higher the density of the sponge. High-quality filling materials can maintain consistent support for more than three years.

5. Detailed Craftsmanship
   The detailed treatment reflects the brand's craftsmanship level:

• Stitching: Use double-stitching reinforcement, with uniform stitch spacing and no skipped stitches. The leather edges are covered flatly without bulges;
• Safety Certification: The gas spring should have an SGS certification mark to avoid the risk of explosion; the five-star casters should have silent rubber edges to reduce moving noise;
• Movable Joints: All movable parts (such as armrest and headrest adjustment parts) should be free of sharp exposed metal or burrs to prevent scratches.
