Serta Pillowtop Mattress Review

I purchased the Serta Vera Wang pillow top queen size, out the door price was just over $1750.00.  After one year of rotating 180 degrees and minimal use due to working out of town, the mattress has a 3 inch sag in the middle.  Serta voided my warranty and will not stand behind their product.  I purchased the mattress protector to have the 10 year warranty, there is not a stain on the protector as well as the mattress.  However, the Serta inspector has some how used super power magnification to find a non-existing stain.  Stay away from Serta, read other horror stories from upset customers brought to you by Serta themselves!
