Is this Eames Soft Pad Chair Supposed to Have Casters?  

Not sure, I believe there was. Would be interested in buying if you want to sell.

Thanks for your response. I am actually selling them, not sure what the rules of the forum are, but if you can private message me somehow let's talk

Though I've never personally seen the loungers with casters, you could easily change them out with the glides. Looks like someone decided to add on the casters to increase mobility while enjoying their cocktail and cigar in a lounging position. Maybe an ottoman with casters too?
