Suckered into buying one once, its no better than any other spring mattress, it gets indentations where you lay like the others, and the pillow top built into it means that when they come to check for a warranty due to the indentations, they lay a ruler across the top and go "nope, it touches, no warranty here."

I will add a few additional insights:

While the tempur-pedic is much better for a bad back than the Sleep Number (because of the Hammock effect), the Sleep Number is light weight and easy to move. Where as a king size Tempur-pedic is a heavy dead weight floppy monster to move.

The warranty on the Tempur-pedic is sort of useless because they measure failure based on how much height the foam has lost from level instead of measuring how much it compresses under load. The foam on a worn out Tempur-pedic will readily spring back to level no matter how worn out the foam becomes.

In sort of the same regard, your actual "sleep number" does not mean the same thing from day to day or from loaded to unloaded. For example, pumping up your Sleep number bed to 100 while you are actively laying on the bed is a softer bed than inflating it to 100 when no one is on the bed. Another example: if you set your bed to 75 on low pressure / hot day, and the next morning it is a high pressure/ cool day your sleep remote will still read 75 even though your bed is now a lot softer. If at that point you try and change your sleep number to stiffen up the bed, the remote will suddenly show a much lower sleep number setting as it takes a reading of the mattresses' current condition.


The trick to buying a temper-pedic is to buy one that is slightly stiffer than you are comfortable with and then put a goose down mattress pad on top of it.

The trick I've had to do to make my Sleep Number bed livable is to set it at 100 and place ~6inches of memory foam on top of it.  (avoid the Sleep number beds with built in memory foam). Also, if you do get a sleep number bed make sure you plug it into a good surge suppressor.

Sleep number beds automatically adjust themselves to your number due changes in pressure caused by outside influences. It should be measured and adjusted while you are laying in bed. If you contort yourself or your wife comes over for a visit it will adjust automatically.

They call it Responsive Air.
