Big Lots Serta Mattresses
Big Lots sells a quality Serta Mattress at a buyers price point.Gerry McCleary in West Mifflin, PA, should contact Big Lots regarding the Serta mattress with a dip and they will determine if it is defective.
If it is they will replace it. All Big Lots mattresses carry a warranty and this mattress should be covered. As far as there not being any material on the reverse side, flip mattresses have not been made for over 3 years. Gerry did not indicate what type of mattress was purchased.
If it is a pillow top or a eurotop, because of the luxury fibers, body impressions are to be expected. The mattress should be rotated and Gerry may try sleeping on different areas of the bed.
Hopefully this will help in better sleeping.
