Wrote a review on this earlier as this is a firm mattress, not soft!  I called Wayfair and they said "sure" you can return it.  Well, about that, there is no one around that can shrink wrap this to send it back.  You would have to return it as "freight" and that can cost you $350.  Soo....I am stuck with a "plush" mattress that is "firm".  I really think I received a "firm" and not "plush".  There is no way to tell if you were sent the wrong mattress.  I ordered a gel memory foam mattress on here for my daybed (a single) and ordered a "medium" but a different brand.  It is softer than this mattress.  Very disappointed.
