Two-sided construction provides a balance between softness and support depending on orientation. One side includes U-shaped channels that follow body curves to reduce pressure, while the opposite side offers firmer support for spinal alignment. A 5-zone design distributes weight evenly across key body areas. High-density memory foam maintains consistent performance during use. The breathable cover is removable and washable, with straps to prevent shifting. Expansion time of 24–48 hours is recommended before use.
