I'm not sure. I had to return the one I bought because it didn't inflate properly. It only inflated on the edges and not in the middle. So I returned it. But maybe I wasn't too lucky. I saw a lot of good reviews and that's why I bought it.

Been using mine for months (less than a year) and can tell no difference in the firmness or shape. The manufacture recommends a mattress pad which I'm sure will help prolong the life of the memory foam.

Celeste, I currently own 6 of them and they are close to being 6 years old. However, I really don't anticipate they will last forever, I have read several reviews of units lasting as long as 15 years. If mine give out today, it's a cheap investment, and they work...

They lasted 3 months for me. Others lasted 1 month. I ues them daily with hot water.

Not sure, I have only had mine for a short time but they are designed well and seem like they would last a long time with proper usage.

I have not owned it long enough to determine this. They have lasted at least a month so far. Sorry...

It really depends on how much you use them but I can say that i use them for around 2-3 hours a day and with that frequency they last about a month.

I read somewhere that these are suppose to last for up to a year. Just make sure you keep them stored somewhere cool.

I really don't know. I had bought it for my mother in law. From what she has told me, they last a good while.

They usually can last a year.....but I personally notice a difference after 6 months.

Depends if you purchased New or Old or Refurbished or so.They do last 3-5 years depending on how well they are looked after.

They last quite a long time, actually. I use NiMH rechargeables, and it's usually several months between recharges.

I truthfully do not know. I do know that I do not change mine every 6 months. I would think that they last a long time as I have not seen any date on them.

They typically last 6 months. It depends on how much you use it. I change mine every 9 months.

They seem to last for a long time. I did not see any spots on them and I have had them for a couple of months. After this weekend, they are all gone.

For me , they last about 4 months. I use them in a home repair business but must add that I do not use them everyday.

They can last for years. I uploaded a video of mine after a few years of use, and I use them often: http://www.amazon.com/review/R236EXQTVCUJA4

Mine lasted about five years, but they went bad because I accidentally stepped on the wire and pulled really hard, if you take good care of them they should last at least ten years imo.
