The perfect balance between firm and soft. It feels like it's made from very durable materials. Definitely worth a try, especially since they give you 101 nights to do just that. What's to lose?.. except a good night sleep.
I would recommend trying GhostBed. I must admit I am not a raving fan as I do not find it "Supernaturally Comfortable" however It is as good a mattress as I have ever slept on. It is definitely a heavy mattress but I am hoping that is indicative of a mattress that will last a long time.
Have the Ghostbed King for three weeks. It is not the revelation we excepted. Mattress is too soft, feels like sinking in. My wife and I wake up with stiff neck, lower back pain. Still giving it the benefit of the doubt and we will wait and see, if we still have to break it in.
Here are some direct quotes from our first few nights with our mattress: "It's like tiny angels are kissing my back" "I feel like I'm being hugged but not too hard, ya know?" "I'm going to cry, I'm so comfortable" "(at 7PM) I'm going to bed!!!" "I feel like we were living life all wrong before we got this bed"... these quotes are just a few highlights. We have thoroughly enjoyed sleeping on this mattress. I'll admit we were a bit hesitate to purchase a mattress without being able to try it first, but it was so worth it. Shipping was super fast and I no longer experience lower back pain throughout the day! Thanks GhostBed :)
