Product review (5 stars): Worked for a 2nd floor laundry room
We purchased some of these just to lift our whirlpool duet steam washer and dryer from the bottom of a water drain pan and they made the washer super quiet. I was really skeptical of having the front loader in an upstairs laundry room and thought it would vibrate the whole house. These definitely absorb a good amount during the spin cycle and keep the house from sounding like it's going to shake apart. The floor is definitely stiffer in the laundry room so it was built for it but I know this still helps keep things quiet.
