Abstract: Air conditioned mattresses have a core and at least one encasement configured to receive a conditioned flow of air into the encasement and to allow conditioned air to flow out of the encasement to a sleep surface of the mattress. Additional conditioned air conducting layers are provided in combination with the encasement.

Abstract: The present disclosure and related inventions includes various mattress constructions with improved air flow characteristics, and in particular mattress constructions which induce or control air flow when force is applied to the mattress support surface.

Abstract: Innersprings with alternating coil spring orientations have columns of interconnected coils in which the axial orientation of the coils alternates one hundred and eighty degrees column to column.

Abstract: A one piece foam mattress core or innerspring encasement is a single contiguous piece of foam having a mattress core or base and four perimeter side supports and which fits with a mattress core or innerspring to provide an integrated mattress construction. The mattress core or base of the encasement is positioned below the mattress core or innerspring proximate to or against a bottom surface. The mattress core or base and the perimeter side supports are connected along fold lines or grooves in the single piece of foam so that the perimeter side walls can be folded to vertical positions about a perimeter of the mattress core or innerspring. The single piece of foam of the encasement is producible in different sizes to fit with different size mattress cores or innersprings.

Abstract: Encased hourglass coils and encased hourglass coil mattress cores have steel wire coils with an hourglass profile encapsulated in a sheet material enclosure, package, casing, housing, containment or encapsulation, wherein coils are enclosed within an enclosure made of fabric, non-woven, or other material which encapsulates each individual coil spring and serves to maintain multiple coil springs in an array or alignment in a mattress core. The hourglass configurations of the coils, wherein at least one helical convolution of the coil body located between the coil ends has a diameter which is less than every other convolution of the coil body, provides a mattress core which has a relatively lower spring rate upon initial compression and a higher spring rate at higher compression loads.

Abstract: Innerspring dampening foam inserts are disclosed in various combinations with mattress innersprings having a plurality of helical form coils interconnected in an array in which the coils are generally aligned in rows and columns, each of the coils having a generally cylindrical coil body formed by helical turns of wire with openings between each of the helical turns of wire, and first and second ends to the coil body also formed by the wire, each of the coil bodies being spaced apart in the array. At least one innerspring insert is inserted into an innerspring in spaces or channels between the spaced apart coils. The innerspring dampening inserts, which are preferably made of foam, may have a generally H-shaped configuration with upper and lower parallel lateral members and a transverse member that extends between and bisects the upper and lower lateral members.
