Gel seat cushion for extended sitting

The Brainwavz gel seat cushion measures 18.9 by 17.7 by 1.6 inches and weighs 2.6 lb. Its double-layer gel construction and honeycomb airflow channels are designed to reduce pressure on the tailbone and lower back during long sessions at a desk, in a vehicle or on a wheelchair.

Simple placement with removable cover

The cushion sits directly on any flat seat without straps or fasteners. A zippered outer cover detaches for machine washing while the gel core stays in place, so cleaning does not require disassembly of the pad itself.

Gel material limits for continuous heavy use

The soft gel compresses under sustained weight and slowly returns to shape when unloaded. In very warm environments the cooling effect diminishes as the gel approaches body temperature, and the 1.6 inch thickness may not suit users who need a firmer or higher seating position.

Questions about this item

How can I confirm the cushion is providing the intended pressure relief after I place it on my chair?

The double-layer gel construction is designed to absorb pressure points; you should feel even support without bottoming out when seated.

What comes in the box and is a separate cover or pump required?

The cushion arrives with its detachable zippered cover already fitted; no additional cover, pump or accessory is needed.

Which dimensions should I match to my seat — the 18.9 x 17.7 x 1.6 inch super-large version or a smaller size?

This model measures 18.9 by 17.7 by 1.6 inches and weighs 2.6 lb; choose it if your chair seat is at least that wide and deep.
