Tempurpedic

Found this one on Ebay.

It’s this gadget you put under your old and uneven mattress to temporarily restore its proper contour. I say temporarily, because really — you should be better off buying a new mattress instead.

Anyway,  if buying a new mattress won’t do for now because your budget is pretty tight, this gadget is up for bid at $9.99…

It has the following features, as indicated in its description:
- Solves the increasingly large consumer problem of sagging mattresses
- Extends the life of currently owned mattresses by restoring support capability
- Adjustable to suit individual support and comfort needs
- Sagging mattresses are a leading cause of back pain

Sleeping on a sagging mattress can throw you off into fits. You wake up not only feeling tired, your emotional state may also be affected from lack of good sleep.

With an inflatable invention like this mattress remedy, the sagging of the mattress is easily corrected. Slipping this gadget in between your mattress and box spring restores your bed in top form condition.

How does it work?  According to their website:

The patented inflatable support bladder sits between your mattress and box spring. The bladder connects to a hose and hand pump. Position the bladder and use the hand pump to adjust the mattress, eliminating any sags or depressions and restoring mattress support.
