I had a Nectar before this Ghost mattress and it was terribly squishy. I had developed pretty bad neck and shoulder cramps and aches. Thanks to the firmness of the Ghost mattress, those aches have gone away.
I like it a lot. It's firm and was a little bit of an adjustment initially. We had one before for six years, and there were minimum signs of wear. We had to replace it due to a situation not related to the company. My partner always complains about other beds when we stay elsewhere now that we have the Ghostbed!
My husband and I had a queen ghost bed. We loved it! We decided to upgrade to a king ghost bed and we love this one too! Definitely the best purchase we have made.
