DXRacer Tank Series Egnomic Gaming Chair for Big and Tall, Heavy Duty, with Water Proof Fabric Upholstery, magnetic head rest and lumbar support, Gray

Megnetic Headrest and Lumbar Support: The specially designed magnets have been seamlessly embedded within the pillow, enabling it to be adjusted to different height settings all over a significantly wider range. Featuring a thicker and wider construction, as well as slow-rebounded memory foam, it offers additional ergonomic support and alleviates pressure on your body. Oversized Class 4 Hydraulics We have customized a larger hydraulic position size with a 70 mm diameter for the Tank Series. Our Class 4 hydraulic position passed the top-level test of BIFMA and SGS certification by lifting up and down 120,000 times without fail. The safety decompression structure design will be more secure than other hydraulic positions you ever use. 4D Adjustable Armrest: The ergonomically designed 4D adjustable armrests move up/down, left/right, forth/back, or swivel to better suit your seating preference. Its extended length of the base plates and thicker screws ensure enhanced strength and durability.
