Mattress Firm

Purchased a Beautyrest, $1,000. After two weeks both sides were sagging. Mattress Firm will not discuss until you have slept on it 21 days. Now, 21 days and sagging even more. To return it is a 20% restocking fee (guess they are going to pawn it off on someone else) and a $99 fee. To exchange it is a 10% restocking fee and a $99 fee. This is obviously a defective mattress. Customer service was rude and offered no help other than to file a warranty claim. To do so... take a picture of every tag (about 6 of them) take a picture of the mattress. Lay something long across the mattress, print out some paper measuring device to prove it sags more than 1 1/2 inch (they will not honor a warranty until it sags this much) take more photos. Remove the mattress from the frame and take a picture of the frame. Upload all into your warranty claim and they will review and get back to you within 30 days. They do not stand behind the merchandise they sell and I don't feel I should be financially penalized for a defective product.
