We purchased our Tempurpedic mattress a little over a year ago. The mattress is fine but the foundation under it fell apart after a few months.
The retailer replaced it and now it too has fallen apart. I just spent a few hours replacing the fiberboard stringers with real 3/4: plywood. The fiberboard had not only warped but had broken in 4 different places.
My side of the bed fell apart the most and I weigh less than 140 pounds so it certainly wasn't over stressed. Do not buy one of these, the construction is less than 3rd rate.
