outdoor dining chair seat cushion

Common sizes include small dining cushions around 20" x 20" x 2", deeper seat cushions about 24" x 24" x 4", and much larger double/papasan styles listed at 47.2" x 67" x 3.94" (approximately 66.9" x 47").

Covers are commonly olefin or polyester. Fill types include 100% foam—many listings specify high-density 28D foam for support—and some larger cushions use PP cotton or 100% cotton fill.

Thickness typically ranges from about 2" (thinner dining cushions) to 4" (thicker seat cushions); a large papasan-style cushion is listed at about 3.94". Several listings specify high-density 28D foam for added support.

Closures are either sewn seams or zippered covers. Many cushions have removable zippered covers for easier cleaning, while others use sewn, non-removable covers.

Many cushions are vacuum-compression packaged for shipping. Listings advise unpacking and allowing about 2 hours or more for cushions to recover their shape; using a hair dryer is mentioned as a way to speed recovery.

The cushions are described as suitable for patio and outdoor dining chairs, patio sofas, terrace chairs, garden lounges, indoor dining areas, and—for the large double cushion—papasan or floor lounging.
