The good: I like the mattress and the quality of it-especially in comparison to SN beds. I can't say it makes a big difference on quality of sleep one way or other, but I like it enough. It also was no problem to put together-I'm a 50 year old woman with no help-and it was a piece of cake once I watched the videos. The not so good: When I received my shipment notice-there was no reference to the fact that the air chambers would be shipped separately and several days later. Only that "my shipment would arrive" So, like another customer, (and 2 calls later) I was left with no bed for 4 days or so while I waited for another package to arrive. The first CSR wouldn't even give me a tracking number for the package with chambers (why not?) the second rep did. I had also placed an additional call to Personal Comfort-but never got a call back. So make sure you have all your parts before tearing down your old mattress. I don't know why I wasn't advised that this was going to happen, but it resulted in me scrambling to figure out where to sleep during that time.
