9 out of 10 couples have different sleep numbers. You get a more comfortable night's sleep on a bed when you can control the firmness of your mattress. How many beds did "we" have to lay on before "we" decided which one you both could live with? You don't have that problem with a SC Sleep Number Bed. Your spring mattress will wear out in 7-8 years and the SC bed would still be giving you a great night's sleep. SC beds last twice as long because they don't have springs and you don't have to flip them. If you don't value a great night's sleep and want to sacrifice comfort for dollars then knock yourself out. Just don't attempt to justify your "frugal choice" by knocking the SC beds, especially if you have never slept on one. The worst part of owning a SC bed is when you go out of town, you miss your bed!
