Does it feel like memory foam? 
No. Not at all. 
Does  it feel like a regular firm spring mattress?
Yes. Exactly like that. 
Do you move a lot? Then it’s perfect for you because moving mattresses is the worst! 
Are you never planning on moving? Then you might as well get a more expensive, real mattress, but still this is really nice for an extra guest bed that can be put away when not in use.
