The picture below is of movable benchrest benches and seats we built several years ago for our local club to begin a Rimfire Benchrest program. We used waterproof flakeboard for tops, P.T. 6x6" legs, and 2x6 framing/supports. They had to be made movable, due to range sharing with a rimfire position-shooting program. They were great for over 18 years and when some concrete benches were installed to increase the number of positions, I got one of the older ones to take to my home range. It's still very solid!
Note that the pieces cut out for each shooting position were used for leg bracing.
One sheet of plywood could be used for 2 bench tops and bracing. Long lag screws were used to fasten the top to legs/braces. Though I haven't priced the materials lately, they might cost about $80 for each bench.
