Purchased approximately $2000 King size bed from Select Comfort in January of 2009. Cannot get mattress to stay properly inflated and bed shows depressions caused by the body on either side. Cannot get the hard center line out of the mattress. Have installed lifts under the air chambers to no avail. Numerous complaints to Customer Service and have elevated to managers(at least that is what I have been told) with no resolution for the problem. I consider the advertisement to be not truthful and that the warranty is usless. I am a very unhappy client. Someone in Select Comfort needs to contact me and resolve this situation now!!! read full review »
