Maio Benri Low Rebound Ring Cushion with Interchangeable Cover

I used this during my desk job, but I've since quit and no longer need it, so I'm selling it.
I used this because the inner part of my buttocks was becoming indented and misshapen from long hours of desk work.
After I started using this, the indentations were no longer a concern. I recommend this for those who have postpartum issues, hemorrhoids, or have had surgery, as well as for those who do desk work or drive for long periods.
It's not flattened and is still in good condition. The spare cover is unused, and the cover that was used has been washed. Thank you for your consideration.

Filling Material: Memory Foam
Shape: Round
[Donut-Shaped Low Rebound Cushion] Desk work and sitting for long periods put a significant strain on the lower back and coccyx, leading to poor posture. This donut cushion is made with high-quality low rebound urethane material, which disperses pressure on the buttocks for exceptional comfort. It's a cushion that prevents hip pain even after sitting for extended periods. It gently conforms to the shape of your buttocks, dispersing body pressure on your hips and lower back while supporting your pelvis just by sitting on it.

[Resistant to Deformation & Premium Cool-Touch Cover Material] Made with high-density memory foam that provides firm support and resists deformation even after prolonged sitting. The cover is made of breathable, cool-touch knitted nylon material. Women, or those wearing skirts or short pants, don't have to worry about fabric marks being left on their skin. The underside of the cover has a non-slip function for stability. This cushion supports correct posture. *Please note: Do not use on light-colored synthetic leather or genuine leather items.
