It is made of gel-infused memory foam that adapts to your body heat and shape, providing medium firmness support without flattening over time. The cushion’s thickness of about 2.75 inches offers enough padding to lift and relieve pressure on your tailbone, which helps improve your sitting posture and reduce fatigue. An ergonomic U-shaped cutout allows your tailbone to float above the surface, reducing direct pressure. Ventilation holes throughout the cushion ensure air circulation, keeping you cool during extended use.

Measuring 17.5 by 14 inches, the cushion fits most standard chairs and car seats comfortably, and it is lightweight and portable.

The removable mesh cover is machine washable, making it easy to keep clean, though the memory foam itself should not be washed.

Some users may find the cushion firm if they prefer softer padding, and the size might not fit very small or very large seats perfectly.

However, a potential drawback could be the standard size, which might not be a perfect fit for all seat types or body sizes. Moreover, while the product boasts durability and the ability to retain its shape over time, individual experiences may vary.
