It was a little awkward, but I bought it because I heard it was good for people with back pain and herniated discs. It seems comfortable. People who don't fit may feel uncomfortable.

I was satisfied with it after using it, so I bought more. It seems a bit long horizontally, but it is good value for money.

I am suffering from a herniated disc, but I found a product with good cost performance and am using it well. This is my second purchase and I want to share it with my acquaintances.
