Purchased a Kingsdown mattress after the 3 min bed match stated it was suited to myself and my husband. What a joke. The salesperson led us in that direction, however it was our choice. He stated mattress is new and needed a "breaking in" period. We knew by 2nd night this mattress was not going to wk. Recently had back surgery. Went back to mattress warehouse and was told to give it at least 7 days. Then returned after 9 days and was told couldn't exchange for 30 days. I called the Kingsdown comp. And customer service could have cared less. After the 30 days had to pay an additional 115.00 plus difference in price 400.00 to get a different mattress. A more familiar brand. Please take this review seriously. It has caused increased back pain, shoulder /hip pain. Toss and turn. On average 2 hrs sleep per night, and this company could care less.
