Have been packing a lot of stuff I've accumulated over the years, also been purging some of it, I decided before we move I wanted my Ikea Expedit bookcases to be more "mobile" so we added the caster bars to the biggest shelf tonight, they don't recommend it but I'm up for taking the chance, hopefully it's still sturdy once I put all the books back on it in the new house! I have two other the smaller shelves which I will do the same once I empty them, the other two will work as divider walls in my new studio...
David A. Fisher patented the furniture caster in 1876.
Want to know a little history about the Caster?
All the books are packed up!
