Fast delivery. Came in a box that I did not believe would hold it.  But opened it up and it was compressed and neatly fitted inside.  When we put it on the bed and waited a little bit, it sprang to life!  The topper covers the cover and mattress perfectly.  The cover feels so soft and silky.  Sleeping on this, wonderful. Keeps you cool and is so comfy. You can buy this Sealy 3" Cool Gel Memory Foam Mattress Topper with cover with confidence!
