NIGP 56535: Innerspring Units

NIGP 56535 Innerspring Units, an Item code, covers the procurement of innerspring mattress cores and related components that state and local governments buy for residential facilities, dormitories, correctional institutions, and institutional bedding programs. The code captures the supply of coiled-spring mattress units in various sizes and firmness grades, typically procured as replacement stock or for new facility outfitting. Issuing bodies soliciting under this code include state departments of corrections, county detention facilities, municipal housing authorities, and state universities operating student housing or residential treatment centers.

No recent state and local contract opportunities under NIGP 56535 appear in available procurement databases. The absence of posted solicitations in this narrow commodity line reflects the sporadic, inventory-replacement nature of institutional innerspring procurement — purchases occur as facilities age existing stock or expand capacity rather than on a predictable annual cycle. Firms pursuing this code should monitor solicitations from state corrections systems and large university housing operations, which represent the primary buyer universe, and prepare to respond quickly when RFQs or ITBs do emerge, as these tend to move with compressed cycles and often leverage cooperative purchasing agreements for volume pricing.
