Mattresses bought from reputable online-based manufacturers should be just as durable as those bought from a traditional showroom, with a lifespan dependent on its type and design rather than where it was purchased. Innerspring mattresses are among the least durable, with the majority lasting 5 to 6 years. Pocketed coil hybrid and all-foam mattresses last slightly longer, at 6 to 7 years, while all-latex beds have an exceptionally long lifespan of 7 to 9 years. Different manufacturers offer different warranties for their mattress in a box models, so customers who want their mattress covered for its full lifespan should comparison shop for a warranty that fits their needs.
