That was a big problem for me, too and using what I had around this is my ideal set-up! I quilt the stab-stitch way, so it may not work for you.
The first pic shows how I lay it out and the second shows how the quilt is ready for quilting.
Can even pull the table over to my recliner or use an office chair. The table is an inexpensive folding one from Walmart. My couch has many cushions which are handy to prop around you to rest arms on, etc - the red one is to lay across my lap under the quilt for more support.
The boards are left over molding and the "weights" to hold them are painted rocks and an old iron!
A big arm chair would work, too if you can drape the quilt over the arms while you sit. Good luck!
