We've only had the bed for two nights, but already I'm seeing a difference. Our older mattress was 15 years old and in need of a replacement. I couldn't get through the night without tossing and turning and trying different positions trying to get comfortable. Of course after a long and useful life it was time for a new mattress. We have heard that foam mattresses sleep hotter than conventional beds, but my wife enjoyed sleeping on our firm foam mattress in our spare bedroom. Where as I enjoy the soft cushioning of a traditional coil spring mattress we seem to have found a happy compromise. We went to a local mattress show room and tried out at least a half dozen beds. We both found that the Serta icomfort plush blue max 1000 had the best of both worlds. The mattress definitely has some of the firmness of a foam mattress and the plushness of a softer bed without compromising support. You lay down in the bed and it feels like it's enveloping you in comfort and support. So far I've been able to sleep on my side for the first time in years. Also my wife came to bed after I fell asleep and I had no clue as to what time she came to bed which never happened in our old bed. In our old bed you could feel every move in and out of the bed by the other spouse. It's definitely a welcomed new change I'm quickly adapting to. So far I haven't slept this good in years. Thanks Serta!
