My husband and I were contemplating replacing our king size mattress when I came upon the idea of purchasing a memory foam mattress topper instead. As it turns out, this was an EXCELLENT IDEA THAT SAVED US A LOT OF MONEY! The GRAND HOTEL 4 inch Comfort Loft Memory Foam Mattress topper totally revitalized our mattress and once again, provides us with a good night's sleep! We were so impressed with this topper that we purchased a topper for our guest room and encouraged family members to consider investing in a Grand Hotel topper before purchasing a new mattress. I would recommend this topper to anyone whose mattress needs a lift.
