FLEXPEDIC Deep Sleep Queen 10" Mattress

Set up was easy, with clear easy to follow instructions, and it seemed like a perfect fit, but I saw some signs with in days that this would not last. It takes a few days to fully "fluff up", but one side of my mattress seemed flat, and never matched the other. I am not a heavy person, but the mattress quickly developed low spots in the top. I rotate it often to try to prevent wearing on the spots, but the side that was lower had become worse over time, and now the whole mattress has a lean to one side, and is leading to neck and back pain. When it was new it was very comfortable, but it has not held up at all. When new it matched the depth listed, but is now inches shorter. There were no smells from the mattress, and it has remained oder free. In the last few weeks I have noticed pop sounds that have me concerned with the spring inside. I will be replacing asap, with a more traditional mattress.
