Ordered this mattress for a 2nd floor bedroom to go on a platform bed. It comes in a box and the mattress itself is vacuum sealed. Super easy to open the seal as a little letter opener blade was included in the box. We put the mattress on the end of the bed and cut the seal. The mattress unrolled itself in about 1 second. Stand back bc it comes out with some force!!  Love how it has springs and foam. Haven’t slept on it yet but seems very comfortable when I laid down on it. Just the right amount of firmness and thick enough not to need a box spring on a platform bed.
