My wife and I both struggled to get through a night without tossing and turning on our conventional plush mattress. Within a year we had a serious sag in our mattress and we woke nearly every morning tired and sore. That's not how you should feel after a night's rest. It took a little getting used to, being a much firmer mattress but sleep is good again. I look forward to climbing in bed at the end of the day knowing I'll feel great in the morning. The reviews I read beforehand appear to be true, as this mattress is on the form side of medium. That may not be the case for everyone, as my wife and I are both below the average for height and weight. The mattress also is also a bit slow to respond to movement. It's great for not waking your partner coming home late but can be a bit annoying when adjusting body position before bed. Overall, I'd highly recommend GhostBed to anyone.
