## Sleep Number Bed

The company manufactures the Sleep Number® bed, an adjustable air mattress. The "Sleep Number® setting" is a setting that adjusts the firmness or softness of the mattress on each side of the bed using air pressure (dual air chambers, one on each side), with higher numbers (up to 100) denoting higher pressure and more firmness, and lower numbers denoting less pressure and more softness. Sleep Number's latest line of beds, the 360 Smart Bed®, launched in 2017. The "Smart" features include Dual Adjustability for adjustable comfort and firmness on each of the bed; Responsive Air® technology, which allows the mattress to respond to movements and automatically adjusts firmness; and SleepIQ® technology, which shows sleep quality via a SleepIQ® score, with personal insights for better sleep. Sleep Number Beds can hold up to 850 lbs. of combined weight, with each side able to support 400-420 pounds.

## Legal issues and controversy

In 2005, Sleepy's, which is now Mattress Firm, sued Select Comfort, currently known as Sleep Number, for disparaging the quality and comfort of Personal Preference beds made by Sleepy's, and said Sleepy’s offered inferior warranties. The case revolved around whether or not Select Comfort violated a 2005 contract that let Sleepy’s sell a Select Comfort product, while Select Comfort sold an arguably superior product in its own stores. The case was originally dismissed in 2015 by U.S. District Judge Joanna Seybert in Central Islip, New York but later revived by the 2nd U.S. Circuit Court of Appeals in 2018 after finding out that the lower court misinterpreted part of the New York law. The appeals court also threw out a $2.63 million legal fee award for Sleep Number. In 2015, a class action lawsuit was filed against Sleep Number and Leggett & Platt accusing the companies of failing to uphold the warranty and fix a bed they sold to customers, David and Katina Spade. The suit claims there were several other customers who experienced similar issues.
On November 9, 2019 Dires LLC, the legal entity that sells the Personal Comfort Bed, filed a lawsuit in Minnesota state court accusing Sleep Number of monopolization, tortious interference, deceptive trade and unjust enrichment. This stems out of a previous court ruling stating that Sleep Number has no trademark rights to the phrase “number bed.” The new lawsuit claims that Sleep Number falsely told Google that it owns the trademark rights for "number bed," causing Google to deny Dires the use of the phrase to attain more clicks to its website. Dires also accused Sleep Number of targeting it with false, misleading and defamatory reviews and comments about its products. They provided evidence of Sleep Number employees posting false and negative comments about its products on Facebook and YouTube.
