Not Durable
I bought two of these mattresses and, although my husband did not develop pressures sores during use, both of them started leaking very soon after the 90-day warranty had expired.  I was able to repair a given leak with Shoe Goo, only to have another one spring up in a new place one or two days later. I repaired new leaks in the first one  10-15 times before finally giving up. I I felt like the mattress was programmed to self-destruct after 90 days.
