Pedestal is likely to make the stacked washer/dryer too high (depending on how tall you are, you may have a problem reaching the dryer controls and getting to the back of the drum). Also not sure how stable a stacked washer and dryer would be on a pedestal.

I got a wall mounted pull down small sized ironing board for a work surface. It is easy to fold up and works great. it is smaller than full sized. I don't iron, but use it to pretreat etc. About $30 and on line site to store with walmart, I think.

Have pedestals, not happy with the noise they amplify from the front load washer. Had to spend $40 on rubber anti vibration feet at HD to help with the noise. They don't hold the size detergent etc I use, unless I lay the detergent sizeways which would be messy.
Never done stacking machines- CAN'T help you there.
