What a difference a mattress can make...Especially when switching  from springs and coils! This is the most gooey and back comforting mattress ever. I originally ordered it for my guest bedroom but made the mistake of âtrying it outâ. I swapped out my mattress for this one, my guests wonât be sleeping on this mattress. I must report there was no smell and it plumped up so fast. If you are looking for a mattress that will comfort your back and sleep all night, then this is the one youâre looking for.
