Big-and-tall gaming chair with 300 lb capacity

The Dowinx LS-MB33 is a new black gaming chair built on a metal frame and covered in PU leather. It supports users up to 300 lb and offers a recline range from 90° to 145°. An adjustable headrest, massage lumbar pillow and patented linkage armrests are included for ergonomic support.

Wingless seat design frees legroom

The seat removes side wings to give extra space for stretching or crossing legs during long sessions. A retractable footrest extends to support the legs when reclined. Five swivel wheels provide mobility on hard floors or carpet without needing a separate mat.

Pocket spring cushion mimics sofa comfort

Advanced spring cushion technology adapts to body movements and maintains resilience over time. The USB-powered lumbar massage adds relaxation without drawing high power. Fixed dimensions include a 28.4" back height and 21.3" widths at shoulder, waist and seat.

Questions about this item

How much weight can the LS-MB33 support before the frame or gas lift reaches its limit?

The chair is rated for a maximum of 300 lb, so the structure and lift are tested up to that figure.

Does the USB-powered massage lumbar pillow generate noticeable heat or fan noise during all-day use?

The massage unit runs from a standard USB port and has no fan; it produces only a gentle vibration with no measurable heat.

What power source must I already have available to use the built-in massage function?

You need a free USB-A port — on a PC, a USB wall adapter, or a power bank — to plug in the lumbar pillow cable.
