After doing a lot of research, and reading a lot of reviews I decided on this Sealy hybrid 14” mattress in a box.  It is very comfortable and supportive.  It is just the right firmness.  My husband and I agree that the hips are cradled and sink in like lying on a cloud.  This is for an extra bedroom, and now we think we may have to purchase another for us.  Shipping was fast, and the mattress was easy to place on bed.  We allowed 24 hours before testing it.  There was no odors noticed.  We love it.
