Although this bed may be great for others, for us it made my exsisting back issues worse and made my wifes back start to hurt. We took all the steps and suggestions from customer service, but to no avail. A word of caution, once you open the packaging you are stuck with the mattress and customer service says to return it will cost almost $300 to have someone come pick up, package and ship back to Overstock. Not the typical repsonse I have received previously from Overstock who is usually great about product issues. Overall the mattress and the resulting issues has been very disappointing.
