I did the same.. I bought replacement wise seats for around $200.. only to get them and to find out that the base was way to small and I really needed a 14 or 16" base. Somebody on this sight recommended veada. I looked them up and was surprise that the seats are custom made to order per your liking. Top quality craftmanship .. marine plywood..etc choose your color and base height 14, 16 or 18 i believe. Thet take a while to make and are almost double the $.. but they will last 15-20 years.. i ended up with a recliner and a helm .. check it out
