What every best Mattresses has:
- Adequate spinal support.
- Motion isolation.
- Freedom of movement.
Owners love the adjustable firmness. According to SleepLiketheDead.com, about 25 percent of owners say the Sleep Number bed has relieved or eliminated pain, especially back pain. In addition, thanks to its electric pump, users on either side of the bed can adjust the Sleep Number's air pressure up or down to find the best level of support for their individual needs, an important consideration for couples who share a bed and want to accommodate the needs of a partner with pain issues without sacrificing their own comfort. SleepLiketheDead.com notes that sagging and other support issues are less common with airbeds than other types of mattresses.
Somewhat pricey. At $1,000 to $5,000 for queen size, the Sleep Number line of air beds costs well above the average price paid for other mattress types. Even so, the top price is lower than that for competitive adjustable air mattresses intended for full time use. Sleep Number warranties its mattresses for 25 years, although coverage is prorated after the first two. In addition, the warranty does not cover compression or body impressions. The company offers a 100-day trial period, and dissatisfied users can return the bed for exchange or refund. However, you must keep it for at least 30 days, shipping and setup costs aren't refundable, and owners must pay to ship the bed back.
Relatively long life span. Sleep Number mattresses last a long time, since nearly any problem with the bed can be fixed with a replacement part. This includes not only mechanical parts like air pumps but also fixed parts like foam toppers. On average, owners keep their Sleep Number beds about 10 years, although at least one in five say their beds have suffered from some type of durability problem, such as leaking air chambers or controller malfunctions.
The Sleep Number bed garners an overall satisfaction rating of 77 percent from around 1,735 users whose comments are analyzed on SleepLiketheDead.com. Owners like its comfort and adjustable firmness, but some complain of an uncomfortable bump or sag in the middle, as well as noisy pumps and mechanical problems.
ConsumerReports.org tests dozens of mattresses, including innerspring, memory-foam and adjustable air models, on criteria that include durability, vibration, firmness and support. Manufacturer claims regarding firmness are also put to the test. Three Sleep Number mattresses are among those tested.
