Great job of repurposing your waterbed. I have a similar ironing surface. I repurposed the triple dresser that matched our waterbed. The waterbed has been gone a long time, but I couldn't part with all the storage space in that dresser. It has lots of drawer space and a 2 door cabinet in the middle. DH made a big board ironing top that fits on the top of the dresser. I now have a 24 x 66 ironing surface. I love it.
