These are great. Mine is from Seals Stadium (as is the cushion), by way of the Tacoma Rainiers. They sold these a few years ago for the bargain price of $75 ea. A buddy made the stands and I had two extra. They work great and I put the pair on ebay for $20. Some other guy who sells seat stands sent me a nasty email telling me mine were junk, cheap, etc, etc. Jeez dude, who asked you?
I recently checked into Candlestick seats...the greedy 49er's are selling them for $700 a pair. Ridiculous.
