Within six months of purchase the mattress was returned because of "grooves" that formed. I am not a real "heffer" at 190 pounds so I do not know why this mattress fell apart so quickly. The retailer promptly replaced the mattress but in four months the replacement had the same lumps and grooves as the first. This time however, the retailer moved and could not be located.
I finally tracked down the retailer I purchased the mattress set from and he informed me that they no longer handle the product because of many similar complaints to mine and the poor customer service that the company (Corsicana) gave its customers.
I was provided with the contact information for Corsicana and they requested information which I promptly provided them. They then wanted my to take measurements of the irregularities of the mattress which was no easy task. I am still waiting to see what if anything they are going to do to make it right.
I cannot recommend Corsicanna to anyone seeking a quality mattress at a decent price. Did I mention, the mattress set I purchased was , at the time, the top of the line; Heritage Series, Bliss mattress.
