The SINWEEK 5-Zone Mattress Topper is a high-density memory foam pad that splits the sleep surface into five zones, each shaped to give more support or more give under the shoulders, hips and lower back. The foam softens with body heat and molds to your shape, and the topper is lightweight enough to lift onto most mattresses. It suits side and back sleepers on a mattress that feels too firm, or anyone with pressure points at the shoulders and hips. Against plain flat toppers it offers zoned support, but it has no straps or grip base and no washable cover, so it can shift and is harder to keep clean than rivals with a removable cover.

This mattress topper is made of gel memory foam and divides the sleeping surface into five zones. Each zone is designed to support and relieve pressure in a specific area, including the shoulders, hips and lower back.
The high-density foam responds to body heat and weight. It molds to your shape and supports spinal alignment. The construction is lightweight, goes on top of any mattress, and resists sagging and deformation.
The foam is CertiPUR-US certified for content, emissions and durability. Allow 48 to 72 hours in a well-ventilated area for the topper to fully expand. A warmer room, around 78°F (25°C), helps the foam regain its shape faster.
