If you have experienced a tempurpedic mattress that feels like it is falling apart and not doing what it did the first year you got it, we may have good news. We noticed the foundation boxes creaking and the bed peaking in the middle. The sides of the bed were like soft cream cheese and there was no support. You sunk so far into the mattress and it was so lopsided that it caused us to be sore and ache all night and each morning.
As it turns out the tempurpedic foundation boxes are made of inferior material. They bow and pit and creak after time. They are not wood based at all but cheap fiber.
We replaced them with 2 other standard box springs, went to Home Depot and had them cut two pieces of 1/4 in. MDF (Medium Density Fibre Board). Our king tempurpedic mattress measured 79" X 74". They were each cut to 74" wide. One was cut longer to accommodate body length from head to under the knee. The 2nd piece was cut to the remainder of the length of the bed. We placed these across the twin box springs, then placed the tempurpedic mattress on top.
THAT SOLVED THE PROBLEM. The bed acts as it did the first time we slept on it.
Reason: The Tempurpedic mattresses are meant to be put on a totally flat surface. A platform bed or even the floor would work. This solution cost us $50.00 and it turned out to be the best one of all we tried. We lived with the bed and back problems for 2 years before trying this. IT WORKS!!
