Placing heavy, freestanding shelving units on laminate is generally acceptable, provided the weight is distributed properly using furniture pads or wide-based supports to avoid damaging the wear layer. It is critical that the shelving is not permanently fixed to the subfloor through the laminate. If a shelf is bolted down, it will anchor the floor at that spot, preventing necessary expansion and contraction, which can lead to gaps or buckling elsewhere in the room. As long as the floor remains a true floating installation, heavy furniture should not cause structural issues.

Can heavy shelving units be placed on top of laminate flooring?
Heavy shelving units can be placed on laminate flooring, but they should not be anchored or bolted through the floor into the subfloor. Because laminate is a floating floor, the shelving weight must be distributed, and the unit must not restrict the floor's natural expansion.
