An upholstered chair, recliner, or sofa with a frame including a pair blowmolded hollow arm rest forms, wherein frame members extend between the forms. Further components may be blowmolded such as a backrest. The arm rest forms and backrest may be reinforced with metal plates and assembled into a recliner. The connections to the arm rest forms providing a geometrically rigid and robust frame that is weighs less, is quicker to assemble, and is more robust. Upholstery sacks are easily attached to the frame.

Mattress assemblies including coil innerspring units, coil innerspring units by themselves, and processes for making the coil innerspring units, wherein the coils within the coil innerspring unit are manufactured with the same geometry, same composition, and from the same gauge wire using different heat treatments to provide the coil innerspring unit with different spring rates.

A pocketed spring assembly comprises parallel strings, each string joined to at least one adjacent string. At least some of the strings have springs of different gauge wire and some of the pockets of the strings having springs of different gauge wire are spliced together. At least some of the strings have springs of different geometries and some of the pockets of the strings having springs of different geometries are spliced together. At least some strings may have end sections with springs different than a middle section therebetween, the springs of the end sections being firmer than the springs of the middle section.

A chair is made of foam, and includes a back stiffener that reinforces the back of the chair so the back does not collapse backwards when someone leans back and puts significant weight on the back of the chair. The back stiffener can be made of a variety of different materials and can have a variety of different configurations.
