Select Comfort of Minneapolis, Minnesota, has manufactured the Sleep Number adjustable air mattress bed since 1987. The company makes the mattress in four different series or models, which vary in quality of materials and price. The bed allows individual adjustment of firmness by adding or removing air pressure within either of its two side-by-side air mattresses using a remote control to operate an air pump. The bed is very different from a conventional bed in that the mattress is composed of several different parts.
Crevice in the Middle
There is a crevice or low area that forms down the center of the bed between the two air bladders. This is especially noticeable when one bladder is aired up more than the other. This has been reported as uncomfortable to lie on. Select Comfort does offer a solution to this in the form of a foam insert.
Value for the Price
Prices for a Sleep Number bed can seem expensive when compared to prices of other mattresses. Many Sleep Number bed owners consider the light weight and use of certain construction materials to be a sign of lower quality when compared to price.
Wear and Subsequent Replacement of Parts
Because Sleep Number mattresses are constructed from separate parts, maintaining the bed can be an on-going process. Mechanical parts, as well as comfort layers and supporting foam may periodically need replacement. The cost of most replacement parts is covered by the manufacturer for the first two years under the warranty. After two years, some of the cost becomes the bed owner's responsibility.
Causes or Worsens Pain
Some owners report that the bed causes discomfort or pain, or that it aggravates pain, mainly from excessive firmness and sleeping on the crevice in the middle. A mattress topper is often used to help alleviate these problems. Air loss attributed to inoperable or malfunctioning mechanical parts and leaking bladders is reported as a cause of pain. Support foam becomes fatigued and losses its ability to cushion the body; replacement is often necessary.
Expensive Return Policy
Any Sleep Number bed can be returned during its 100-day trial period. However, original shipping and return shipping costs are the responsibility of the customer and can amount to several hundred dollars.
