Big-and-tall gaming chair with massage lumbar

The Dowinx LS-MB33 is a new gaming chair built on a metal frame and wrapped in black PU leather. It supports up to 300 lb and includes an adjustable headrest plus a USB-powered massage lumbar cushion. The seat reclines from 90° to 145° and features a wingless cushion design for extra legroom. A retractable footrest and patented linkage armrests complete the package for adults who want a wide, supportive seat.

Check your space and USB power before ordering

The chair measures 28.4 inches tall at the back and 21.3 inches wide at the shoulders, waist and seat. Weighing 37.15 lbs, it ships in parts and requires assembly on its five-wheel base. You will need a free USB port on your PC or a standard USB charger to run the lumbar massage function. Ensure the reclining range and footprint suit your desk area before purchase.

Thermals noise and power in normal use

The PU leather upholstery and pocket-spring cushion promote airflow, keeping the seat surface closer to room temperature during long sessions. Mechanical noise is limited to the recline mechanism and the low-voltage massage motor, which runs quietly off USB power. Power draw is minimal, adding only a small load to the USB supply without affecting system thermals or acoustics.

Questions about this item

Does the LS-MB33 arrive with the headrest and massage lumbar pillow, or must they be purchased separately?

The box includes both the adjustable headrest and the massage lumbar pillow, so no extra accessories are required for those features.

Should I pick the PU leather version or a fabric option for the 300 lb capacity model?

This LS-MB33 is offered in black PU leather only; there is no fabric variant listed for this model number.

How does the 90° to 145° recline range feel when the chair is used at a desk for long sessions?

The range lets you sit upright at 90° for focused work and lean back to 145° with the extendable footrest deployed for breaks, all while the pocket-spring cushion keeps support consistent.
