It is not uncommon that most mattress manufacturers produce mattresses with a variance of up to 1″ (inch) on both width and length. This can be seen most often when comparing between mattresses made from different materials (such as: rubber (latex) mattresses, coil (spring) mattresses or foam-based mattresses) as well as by different companies (or brands). The official measurements that set the standard are followed as closely as possible and variance in measurement is considered normal by the industry.
