It worked great to elevate my husband’s pain but it developed a hole in a seam around one of the openings and would not hold air one week after purchase.Very comfortable. At first it looks under inflated, but it is not. It’s perfectly inflated.While the product is comfortable and helps with my broken tailbone, the product sprung a leak within 2 months. No sharp objects were brought in contact. The leak was in the seal of one of the holes. Too late to return.Did not state I needed to inflate myselfI have tried many cushions and this one beats the rest by far. My only problem with this product is that small holes/leaks develop in a relatively short period of Tim (a few months). I spoke to someone in customer service and was told that holes can easily be prepared by using a patch commonly found in bicycle store, unless these leaks are on the deans.Every single leak I found was in this area. I have no choice but to purchase a new one. The short life of the cushion makes the cost expensive. I wish the company would find a way to make the cushion seams more durable.Does the job.this didn't last long. I had to get one of these because of an open wound which made sitting uncomfortable. At first, it worked great. But then it developed a leak. Got it replaced (for free) and then went about my life...only to have the replacement develop a leak!Not worth the $It was great. But then deflated and we can never find the leak. It lasted about four months.
