Bought this to make a queen guest bed more comfortable.  Asked guests if they were comfy on the mattress (yes).  I have a Temperpedic Cloud king mattress on my bed that I love -- it's not a topper.  Then I hurt my knee and had to use the guest bedroom downstairs with the Cloud 2" Memory Foam Topper -- it's so nice, that I'm unable to detect a difference between sleeping on the Cloud topper vs the Cloud mattress.
