The invention relates, generally, to a mattress assembly with a mattress cover and a method of transporting and assembling a mattress using the mattress cover assembly.
Mattress covers are used to protect the surfaces of mattresses from soiling and are removable for the purposes of cleaning the cover in the wash. Mattresses are often times transported in a rolled up and compressed (vacuum packed) state via common home delivery carriers. The carriers have weight and size limits for their standard service. The weight limit is 149 pounds fully packaged weight. Online mattress brands that ship via the common carriers have low density mattresses the fall below the weight limit. Foam mattresses may have foams with higher foam densities or other constructions of materials with higher densities and the weight limit of the common carriers results in a limit on the thickness of a mattress especially in the larger mattress size formats. Typically, high density foam mattresses are limited to a thickness of about 8″ due to the weight limit, while other compressed mattress that are not high density are of a 12-14″ profile.
US Patent Application Publication No. 2007/0067916 to Poston discloses mattress encasings and apparatuses to encase a mattress topper. The mattress encasing is constructed with a zipper half at a top edge of the mattress encasing.
