Thank you for viewing. I purchased this in December 2025 to alleviate lower back pain caused by long hours of desk work. I used it about 5 times, but it didn't seem to suit me, so I'm putting it up for sale. Below is an overview of the product (quoted from the official website): ◾️Product Overview The PRO Plus, with its soft seating comfort, has been newly introduced to the PRO, which is part of the Medicoore series, boasting the strongest support in the Backjoy series! Recommended for those who sit for long periods at work, doing housework, or working from home. Features of PRO 1) Difficult to shift The material that stretches in 4 directions fits the buttocks perfectly. Reduces seat slippage! 2) Sitting comfort Employs jacquard weave with a three-dimensional feel and luster. Luxurious and highly cushioned! 3) Breathability It doesn't get stuffy even if you sweat, and it has a soft touch. Smooth and comfortable! Features of PRO Plus Grip added to the position where the ischial tuberosity (sitting bones) touches the PRO, which is difficult to shift! Grip is 29% up (compared to our conventional products), making it difficult to shift! "Non-slip" is the most important thing for long sitting postures. ※As of March 2026, the Medicoore Relief Pro Plus was out of stock. ■Regular Size Height: Approximately 10cm x Width: Approximately 40cm x Length: Approximately 40cm Weight: Approximately 450g Weight Capacity: 50kg - 135kg ■Color Black ※Shipping will be in a simple package, covered with cushioning material such as bubble wrap and placed in a bag.
