i have used one (2" thick)...
alot depends on the mattress u r gonna use it on. I used on 2 mattresses i have:
*it works best on flat mattress (not toooooo soft- Spring)
* it is tooo thin, only 2")
* Company is not very good with warranty issues
* much cheaper ones available which are better and replacable for the price you pay.
