Defective product

I purchased a king size Ultra Plus Euro bed on sale for $897.00 + $50.00 delivery fee + $62.79 in taxes, so you could say a $1,000 king size bed.  This bed is definitely not a Posturepedic Ultra Plus Euro Pillow Top Mattress.  Me & my husband have severe back problems & as result of sleeping on this bed created more pain than we had before, which defeated the whole purpose of buying the bed.  I complained, they send a 3rd party out and they replaced the bed.  It was so bad that there was a hump in the middle and the astro (?) foam did not return to it original position.  The second bed was even worse !! I called again and they sent another independent agent out to verify the defects.  But at this point we could no longer sleep on the bed due to the pain it had caused us, therefore, we were rejected, so now we have a bed we cannot even sleep in....Do not Buy from Macy's, if you check, every year they discontinue something and I guess our's definitely a reject.  What a waste of money and a scam
