What to know before buying

Listing details to confirm

The listing title calls the topper extra firm, while the feature and FAQ text describes two reversible sides, one firm and one extra firm. It also lists cotton as the fabric type but separately identifies gel memory foam and high-density polyurethane foam as materials. Confirm the exact cover and layer construction in the selected listing. The listing says it is not a medical product and cannot cure back pain or correct spinal alignment. Claims about cooling, support, and relief are manufacturer descriptions, not established medical outcomes.
