We got this bed about 3 weeks ago. The first 2 weeks, the bed was too hot, and rustled every time you moved.
We realised the plastic mattress protector we were given for the extra warranty was the problem; a cheap plastic sheet that didn't fit the bed properly, and was like the one's you give to 2 year olds in case they wet the bed!!! We have changed this now, I guess this will invalidate the warranty, but the bed is great now.
We took the Super King Size with Ottoman option which is really useful.
