At home I've only worked with baby quilts and am using a hoop lap stand for those. They don't have much weight to them, but we'll see how it works when I move to a queen sized quilt (although the maker-- Jean Brown (I think her husband makes them) says she's used one for all her quilts).
When I quilt with the group, we lay out the quilt on a couple tables. When we're done for the afternoon, we roll up the quilt and put it in a pillowcase and collapse the tables if we need to. There are also a couple quilting frames, but they do take up some room.
ETA: When I use my lapstand hoop, I use an "Aunt Becky" to quilt. When I do it with the group with the quilt on a table, I just do it "normal".
