Review on Serta Raised Queen Pillow Mattress by Threlkeld Drauch

*Update*: July 15, 2017 - Downgraded from 3 to 2 stars. My second bed was replaced under warranty and I am now in my third bed. The second leaked air from the "NeverFlat" block. Unfortunately, the third bed holds air, but the inner seams appear to have come undone. Now it's like a giant round balloon that I can't put sheets on, or even the pad that came with the bed! But it's still pretty comfortable. It is great as a temporary bed for guests. But for long, decent sleep, look elsewhere. They are very comfortable; When properly inflated and covered with a pillow or two, it can rival the comfort of a bed in an expensive hotel while still retaining the portability and flexibility of an air mattress. I bought my first in November 2013. I slept about it. most days until around August 2016, when it began to decline. I would give 5 stars for this endurance. Pleased with how long the first lasted considering its price, I bought the second in September 2016. This one is already draining because, ironically, the secondary "never drain" device is leaking. Weak! I would give 1 star for that. So on average 3 stars. In all, I spent about 40 months sleeping on two of them. If you are happy with the average lifespan of your air mattress of 20 months with almost daily use then this is a great option.
