What to know before buying

Listing details to confirm

The listing gives both “Charcoal Black Mesh” as the color and “100%cotton” as the fabric type, which do not clearly describe the same covering. It also calls the shape rectangular while describing a double-arc design. Confirm the cover material, actual shape and dimensions before purchase. The seller says the compressed cushion may feel firm at first and recommends leaving it unfolded for two hours to regain its shape. Its pain-relief and durability statements are manufacturer claims, not guaranteed results.

Who is it for?
