I bought a king sized dual chamber Sleep by Number bed a little over two years ago.After the first 6 months, the bed developed a ditch down the middle.
If you moved toward your partner, you fall into this trench. I opened the bed and found the piece of foam (egg crate) was ripped. I called Sleep by Number, and they won't replace it. IT IS A MAJOR DESIGN FLAW IN THE BED.
IN THE CENTER OF THE BED IS A SMALL PIECE OF FOAM THAT IS SUPPOSED TO SUPPORT THE EGG CRATE. IT CAN'T, AND THE FOAM WILL TEAR!!!!
Be aware that this design flaw will happen to you.Their 20 year "warranty" is pro-rated, so after two years - at their rate - they are making a profit on replacement parts that are under "warranty".
DO NOT BUY A BED FROM THIS COMPANY UNLESS YOU WANT IT TO ONLY LAST 2 YEARS!!!!
Monetary Loss: $100.
