I wanted to use this for desk work, but I haven't used it. It's new, unused, and in its original box! The second image shows a photo of it actually placed on a chair! Belle Plage Retail Price: ¥3,980 【Supervised by a Doctor of Medicine】 This high-quality lumbar cushion is supervised by a doctor of medicine. It was developed by someone who is on the front lines every day and knows the human body's mechanisms inside and out. 【Feel the relief from back pain】 It's designed based on ergonomics and firmly supports the S-curve of your lower back and spine. It supports your lower back firmly, naturally straightening your back and reducing the strain on your lower back. 【Target Users/Locations】 Recommended for those who do a lot of office work or long-distance driving, pregnant women, and anyone who wants to sit comfortably. You can use it in various situations and locations, such as during work or while driving a car. 【Guides you to the correct posture】 Without a lumbar cushion, your lower back and back will sink too much, leading to poor posture. As a result, it puts a lot of strain on your body. This lumbar cushion supports your lower back and distributes body pressure, allowing you to maintain a stable posture. It also reduces the strain on your lower back, making it comfortable even when sitting for long periods. 【Excellent breathability and prevents stuffiness】 The cover uses breathable mesh material, making it less likely to get stuffy even after prolonged use. Thank you for looking.
