Received the Slumber Solutions 3" Memory Foam Mattress Topper in a timely manner. Opened it to allow it to breathe and expand for about three days until placing it on the bed. Was very happy with the quality and condition. Purchased a king size and it fit my new bed perfectly. (Had purchased a Sealy topper several years ago and was pleased but the topper had some minor splits and I had to order a king size to fit a queen bed and then cut it to size.) The odor was minor and completely gone in the first three days. Both my husband and I have bad backs and appreciate the support and comfort of the memory foam. I would purchase this topper again.
