Hackers Help: Taller MULIG Valet Stand?


I have a MULIG valet stand that I am basically using as a (semi) privacy screen in my somewhat non-private cubicle. The problem is it needs at about 4″ more to be effective.

I thought that it would be a good idea to elevate it by putting on casters so that I could easily roll the valet stand. However, the base of the stand isn’t very strong and I feel almost like it would need stabilizers. It’s probably easy enough to drill holes at the base of each of the 4 legs and attach a wheel. However, I feel like the IkeaHackers community can come up with an even better idea!

Any help/ideas on how to raise this stand up about 4″ (preferably by adding wheels!)?
