The Sleep Innovations 3-inch topper is designed to convert a firm mattress into a medium-support sleeping surface. It uses a high-density open-cell foam formulation that excels at motion isolation, which means movement on one side of the bed is less likely to be felt on the other. This makes it a practical choice for light sleepers sharing a bed.
The foam is infused with gel beads to help manage surface heat. While this provides a cooling sensation initially, it is a passive feature that equilibrates with body temperature over several hours. The 3-inch depth is specifically helpful for side sleepers, as it allows the shoulder and hip to sink slightly, helping to maintain better spinal alignment. The foam is CertiPUR-US certified, ensuring it meets standards for low VOC emissions.
For the best results, the topper requires a full 48 hours to reach its intended 3-inch loft after being removed from its packaging. This allows the cell structure to stabilize and prevents edge collapse. Because it is made entirely of foam, it does not provide rigid edge support, so it is most effective when placed under a tight-fitting mattress protector or deep-pocket sheet.
If you need a protective layer for a much smaller mattress, such as a crib, the Tempur-Pedic Cool Tot Protector offers moisture-wicking technology in a compact size.
