A dual-sided mattress topper offers two firmness options to suit different sleep preferences. One side features 1-inch firm foam with wave-cut design for structured support, while the other side includes 2-inch soft memory foam that adapts to body contours. The 5-zone ergonomic layout distributes pressure across areas such as shoulders, back, hips, and legs. High-density slow-rebound foam maintains shape while supporting spinal alignment. A breathable, removable cover with zipper and adjustable straps keeps the topper securely in place. It is recommended to allow 24–48 hours for full expansion after unpacking.
