Been using it for a month now. But no relief in back pain. Infact every morning i experience pain in new zones i.e shoulder, right or left side in lower back. I presumed that body would adjust to memory foam and may be the pain is primarily because of switching from coir mattress to memory foam mattress but it seems not to be the case. Switched to hard foam mattress for a week in between. And all the pain was gone. Now i have flipped the wakefit matress to upside down (white side down). Will use it for a while then update.
