Office Chair, SPRDENG Ergonomic Office Chair with Two-Way Adjustable Lumbar Support & Headrest, High Back S-Shaped Computer Chair with Flip-up Padded Armrests, Swivel Task Chair for Home Office

How Does the SPRDENG Office Chair Achieve Ergonomic Design? First of all, the backrest of the SPRDENG office chair not only achieves a high back but also offers a wider back support, being 2 inches higher and 2 inches wider. The waist support that can be adjusted up and down and forward and backward (the only one on the market) not only meets the needs of tall people, but also the fully adjustable office chair can meet the needs of medium and small people.

Fully Adjustable Office Chairs, Customizing Your Exclusive Sitting Posture: Our office chair has added adjustment functions in the following details: The seat cushion can be adjusted within a range of 10 centimeters up and down; The headrest can be adjusted within a range of 5 centimeters up and down. The lumbar support can be adjusted up and down and forward and backward within a range of 5 centimeters. The soft armrest can be lifted 90°, making it convenient to store under the table.

The 135° Tilt Angle Helps You Relax: By rotating the adjustment knob under the seat cushion, you can adjust the inclination of the backrest. When you are working hard and need the office chair to support your back, then tighten the knob and the backrest will be fixed at 90° to provide you with support. When you want to relax, you can make the backrest move by adjusting the knob.

Thickened Seat Cushion and Padded Armrest Provide a Comfortable Experience: The interior is filled with high-density sponge and the surface is covered with high-density mesh. The design of the seat cushion and armrests fully takes comfort into account. Every time you sit down, you will feel a different kind of comfort. When not in use, you can lift the armrest at a 90° Angle and then store it under the table.

High-density Mesh Surface Ensures Breathability and Durability: After testing many different styles, we have used thickened high-density breathable mesh for the seat cushion, backrest, headrest and armrests. The mesh surface is thicker and tighter, especially the mesh surface on the back, which can provide support for the user while also ensuring excellent breathability.

Steel 5-star Base, 300 LB Load-bearing Capacity: We replaced the plastic base with a steel 5-star base, which makes the appearance more beautiful and durable. However, the cost we invested is also higher. Even users weighing over 300 pounds can use it with confidence.We are very confident in our products.

SGS Certified Level 3 Gas Lift and 360° Swivel Casters: Our office chairs are made of commercial-grade materials. The 3-level gas lift ensure smooth and durable use. The office chairs are very suitable for both home and office use. The 360° rotating universal wheels have undergone hundreds of tests before leaving the factory. We use this model in the office and at home. It's not an inferior office chair.
