Sapira is a company that ships mattresses in boxes (a service similar to companies like Casper and Tuft & Needle.) However, what separates Sapira from its competitors is the material of its mattresses -- other boxed mattress companies offer only foam or latex mattresses, but Sapira's mattresses are made from springs.
Sapira is a new brand from Leesa, a company that has sold mattresses for years, but Leesa's previous offerings have all been foam mattresses. As such, Leesa is positioning Sapira as a more luxurious option. The Sapira mattress is an inch thicker than the foam Leesa mattress, and it weighs in at 98 pounds for the queen size. Further, the spring design disperses weight on the mattress better, making it harder to disturb one's partner while sleeping.
