Hello, My husband and I are having Whirlpool Duet washer and dryer delivered next week. We found a pair of pedestals for A LOT cheaper than reg price but not sure if they will cause issues, as the dimensions are not a 100% match. Our W/D call for a pedestal that is: H: 15.5 x W: 27 x D: 26.25 The ones we are looking to buy are made for GE and are H: 15 x W: 27 x D: 28.75 The height and width are fine but it would be sticking out in the back a bit (which I don't care about-as long as it fits). Does the washer/dryer need to snap into the pedestal or would it be ok? Thanks!
