CHECK OUT amazon.com for a vendor that sells NEW but old stock boat seats for about 20-25% of the same exact seats from BOATUS.
(That's where I ordered the lounge seats for my 19 foot utility/runabout & for less than 250.oo for 4 sets, I got some VERY NICE seats.)
Offhand, I cannot remember the vendor's trade-name but his "discontinued & surplus" seats won't be hard to find on Amazon.
