I needed a mattress for a platform bed for my college student.  Wayfair was easy to work with, the bed arrived on time as scheduled and within 24hours it had fully expanded to the proper size.  The mattress looked like a good quality one and also the cover was great as well.  We were very pleased.  It hasn't been enough time yet to comment on how good it sleeps.  It is a FIRM memory foam mattress so if you don't want a firm one you might choose another.
