Tempur-pedic Mattress - $150 (Vilonia)

Two Twin XL Tempur-pedic mattresses.
Use together for King Size Bed.
1,200 new each.
About 12 years old.
We are second owners.
First owner had a back injury and slept mostly in a recliner.
We have had them for 8 years.
Used about 75% of that time (husband has back trouble and slept in a recliner also.
Wife used hers part time and another mattress part time).
There is some breakdown in the overall support, which is why we are not asking higher price.
Super heavy foam.
Removable, washable covers.
Non-smoking, no pet home.
Ask $150 each or $275 for both.
