Zazzle paper quality for seating chart?

I hope I put this in the right category. Anyways, I’m looking at getting our welcome sign/seating chart from zazzle. I got our invitations from there and loved them. My worry is that by the time I get my rsvp’s in, make the seating chart and order it, that if it comes in on too flimsy a paper it won’t hold itself up on the easel we’re using and I won’t have time for them to create and print a new one. Has anyone ordered a seating chart from zazzle that they used the way I’m describing? If so what was the name of the paper you used? They have so many different options but it’s hard to tell until you actually see it in person and I need kind of like a poster board material. I know it would be easier to make one myself but my writing is awful and I have zero creativity. My FH has good writing and is creative but I’ll never be able to get him to sit down and write out/design a seating chart. Thanks!
