Well, we made a decision and luckily, the Sleep Number store is only about a mile from our house and so we went back and paid for it.  He said that it will be delivered and set up in about 2 weeks.  Greg said if it helped with my body pain, it was well worth the money.  He has a lot of headaches which come from his shoulders and neck getting stiff and hurting, so hopefully it will help that also.  It is funny, because our oldest son just asked us last night if he could have the queen size bed that is in one of our guest rooms.  He said his mattress set was shot and he really hated to spend the money to buy a new one.  We told him no because we use it when we have company.  So, I called him as we were leaving the bed store and told him he could have our king sized set.  He was thrilled.
