Hi Maxcook64,
If you don’t notice some improvement in the first week or two then it’s likely that the mattress is too soft for you (the Cloud Luxe is their softest mattress) and that you are sleeping out of alignment. If this is the case then it’s not likely to improve but your own personal experience is the only reliable way to know for certain.
If you purchased directly from Tempurpedic then you have the ability to get a refund with only a small fee … otherwise you may be limited to an exchange for another Tempurpedic (depending on the policy of the retailer you purchased from).
If you are still experiencing the type of pain you are after a week or two I would call them to ask if they can make an exception and do the exchange a little sooner but before you decide on an exchange I would make sure you have read the tutorial post here and test the other options you have very carefully because if your next choice also isn’t a suitable “match” for you then you would probably be stuck with the mattress and have no further options available.
If you are able to get a refund then there are many other memory foam options available to you that are the same or better quality as Tempurpedic and much better value.
