Sleep Number as a whole makes a pretty good product, although not nearly as good as their advertisements would lead you to believe. My wife and I purchased a Queen size Sleep number bed with new adjustable base and foundation with mattresses. Part of the reason why we did this was because they were so adamant about the quality and how they were lifetime warranty covered, and no other mattresses had that coverage! Over all we spent around four thousand dollars, and for the first few years all went well. Now as we began to age, we began to use the bed more especially the adjustable base. This led to failure of the remote control both for the adjust able foundation and the air pump control. We then found out that these were only partially covered by that lifetime warranty. We had to replace them both, one of them twice and each time it cost over two hundred dollars and took a week or so to get the replacements. Next thing that happened was the adjustable motors began to fail. We have now had to replace the head of the bed motor now three times, and not one of them cost us less than two hundred dollars or more warranty or not! We have had the bed over ten years as they point out to us when there is a problem, but that was one of the reasons they used to get us to purchase it in the first place. Each time something fails they say it is being shipped for free using overnight but there is no way to track these shipments. When the item does not show up for a couple of days we call them and they always explain to us that because it was shipped via expiated means, it would likely not show up for a week or so. That has been the case on every order, so far. It is inconvenient when the adjustable parts does not work and causes some difficulty in sleeping. The current problem is however the by far worst. On the right side of the bed, one morning three days ago, we heard a noise that sounded like cloth ripping in the bed room. We went to look, and there was gigantic blister shaped lump on the right side of the bed, a call to customer service was made because this seemed to represent catastrophic failure of the mattress. Customer service told us once again that we would be charged for the replacement but it would be a prorated charge, which turns out to be 118 dollars plus tax, which according to them saved us the whopping amount of 37 dollars. Now, I have become disabled and have two places where I can rest one is my wheel chair and the other is the bed. Now with this lump in the bed it is impossible for me to be able to lay down on that side of the bed, which just happens to be the side of the bed that is setup to transfer me to and from the wheel chair to the bed and vice versa. So, since this happened I have to sleep setting up in my chair which according to the doctors is likely to cause blood clots to form in my legs which could be fatal. Customer Service told us they would ship the new mattress over night. That was three days ago today, and when we call them trying to find out when it will arrive, we get the exact same service as always, they told my wife today that since the mattress was shipped expedited we could probably receive it my the first part of the week. So here I am, I own one of these futuristic beds that is so much better than a conventional bed, and it is lifetime guaranteed that has suffered failure and which leaves me in what could be considered a life threatening situation. With a company who's idea of expedited shipping means a week or so! To say I am displeased is the understatement of the year. Also anyone who is considering purchasing one of these beds, be aware that if it requires service, you will have to deal with the company to get the part then contact someone they recommend to do the labor, which usually results in even more delay in getting the repair done. My own opinion is that a catastrophic failure which makes the bed unusable should result in the replacement of the whole failed part without charge to the owner. That would be a lifetime warranty, at least with a conventional bed you may end up with a wallowed out hole in the mattress which you can stuff full of material to create a make shift work around, but when it is a huge lump in the center of the mattress from top to bottom you simply cannot let enough air out of it to make it a sleep able surface, and you for sure cannot use it with the wheelchair transfer equipment. I would never be able to recommend one of these beds to anyone, especially anyone who plans on keeping it more than five years.
