If you want to lighten up your seat a bit, there are a couple of ways to do that and keep the strength. One is to cut out a section of foam and fill it with styrofoam block or self expanding foam. This can make the seat a bit firmer though. Another is to core drill holes and fill that with spray foam. Try getting a cheap seat that has a bad cover from ebay or something and test it out on a spare foam. You want something firm, like that really dense packaging foam they wrap heavy metal things in. Super light and very strong. Use silicone to glue in the foam blocks if you go that route.
Back in the day, long before Boss patented the lightweight seat design, a lot of the seats were made with a block of styrofoam in the middle. Some of them were even inserted during the mold injection process. Cat, JD, Polaris, Skidoo, Yamaha, and many others used that process.
The way Boss makes the seats lightweight, is a similar process. They made the lower half in styrofoam and the rest of the upper foam was a lightweight open cell foam. They did omit the heavy plastic or wood bases that add a ton of weight.
Hope that helps!
