We bought our mattress (The Sleep Number) in 2005 from Sleep Train and payed $5000. We thought that it was the mattress we were looking for. They did a great advertising and confirmed us regarding the comfort of the mattress. It was sold with 20 years of warranty. For about two years it was fine, but then we have been having constant issues . The mattresses kept loosing air. We set it for 90 before we went to bed, but by the time we woke up, both sides lost air gradually. I started having major back ache, and called their customer service. Few times, they replaced our air chambers, then air pump box, but no use!!! We wanted to give it back since it had a warranty, they refused. So, twenty years warranty does not mean anything!
I asked for a technician to come to our home and fix the problem, they did not have one. They could only give you instructions on the phone to find the issue. But, still don't work. Then, they offer you some pieces and convince you that it will work better. They sell you and charge you for shipping. The result; useless!!
My bottom line is, it has been an expensive junk!! ripp off!!!
They just lie in their ads.
