I have enjoyed my ghostbed. It is comfortable and has that "sinking in" feel, but is also firm and feels mostly supportive throughout my body. Weight distribution feels even.
I purchased this bed for my daughter. She's been sleeping on it for 2 weeks now and absolutely loves it! She's moving into her own place now and instead of letting her take this bed I'm buying her another one!
My boyfriend and I hesitated to buy a mattress online but decided to take the plunge and picked the ghostbed after reading all the reviews. Best choice we made so far, it's really comfortable, very minimal if any disturbance when one of us gets up. We did a test to see if we could feel the other sitting down with our eyes closed and couldn't tell at all. All in all 10/10
