The back cushion features a three-dimensional breathable mesh fabric with durable leather side panels, providing excellent airflow, wear resistance, and easy maintenance. The pressure-relieving memory foam adapts to the body's natural contours, helping distribute pressure and reduce discomfort during extended periods of sitting. Available in two thickness options: 40mm and 90mm, allowing users to choose the level of comfort and support that best suits their needs. The 40mm standard cushion offers balanced comfort and everyday support, making it an ideal choice for daily use while maintaining a slim, lightweight profile.
