Aireloom is a Californian brand of mattresses, all of which are made by hand.
From the Aireloom website:
Aireloom mattresses are constructed by dedicated artisans who bring decades of unique experience to their work. "Mass production" and "mattresses-per-minute" aren’t words you’ll hear in the Aireloom studio. The process is a labor of love, focusing on every cut, every stitch and every layer. The result: Handmade mattresses that set the industry standard for luxury.
