Ergonomic Gaming Chair 300 lb

The Dowinx LS-66D50M is a new ergonomic gaming chair built for adults who spend long hours at a desk. Its metal frame and 5-point support zones follow natural body curves to reduce fatigue. The chair includes a headrest and massage lumbar support for added comfort during work or play.

90°-145° Recline With Linkage Armrests

The backrest adjusts from 90° to 145° and locks at any angle via a free-lock mechanism. A Grade 3 gas cylinder enables smooth height changes and 360° swivel. Linkage armrests move synchronously with the backrest, keeping elbows supported in every position.

19.7" Seat Width and 300 lb Capacity

The extra-wide 19.7 inch cushion combines high-density memory foam with silent pocket springs under breathable PU leather. This construction supports up to 300 lb while delivering a sofa-like feel. At 38.6 lbs total weight, the chair remains stable on its five-wheel base for daily use.

Questions about this item

How does the 90°-145° recline range work when I am sitting at a desk versus leaning back?

The backrest locks anywhere between 90° for upright typing and 145° for deep relaxation, with a free-lock mechanism that holds the angle you choose.

What does the Grade 3 gas cylinder mean for daily height adjustments?

The Grade 3 cylinder provides smooth, stable height changes and is rated for the chair’s 300 lb capacity, so it won’t drop unexpectedly under load.

Will the 19.7 inch seat width and 31.7 inch back height fit a standard door frame for assembly?

The assembled chair stands about 31.7 inches tall at the back and the seat spans 19.7 inches wide; both dimensions clear typical interior doorways when the base is attached.
