I purchased a full-sized Simmons Classic mattress (Breesport model), box spring and frame from a local store. The bed has been used very lightly (in a guest room by average weight persons) and the bed already sags on the side that gets the most use. It is brand new!

The mattress developed a huge mold spot in less than 2 years. Nothing was ever spilled on it and it was placed on a clean surface. Both Simmons and us-mattress.com failed to honor the TWENTY FIVE YEAR warranty. Waste of money and time.

I bought a high end Simmons mattress. The mattress started sagging after one year even with flipping and rotating. I kept flipping and rotating and now after 5 years you have to hold on to the bed because you fall off the edge or sleep in the middle which doesnt work for two people. I called the company and they sent a representive out to look at the mattress. They denied replacement after looking at the mattress because I only had 6 wood slates on each side of the bed, on the wood frame. I looked up on the internet and most beds only come with 3 or 4 slates.There company set the bed up in my house and never said I needed more slates at that time. They will look at the bed and find a reason to denied the warranty even though they will tell you at the store it has a 10 year warranty. I would never buy another Simmons.
