Fill density and firmness vary by model; listed options include medium, firm, and extra-firm fills.

Several pillows list cooling features such as cool-touch (including cool-touch memory foam), gel-infused cooling fibers, and gel or gel-foam fills designed to reduce trapped heat.

Options include single pillows, two-pillow packs, and multi-piece sets such as adjustable or wedge-support kits (a six-piece wedge kit is listed).

Listed fill materials include 100% polyester, memory foam (including memory foam blended with recycled polyester), down alternative, polyurethane foam, gel foam, and gel-infused fibers.
