BeadSeat - Creafoam Seat Kit - XL 30Gal

When you need to build your custom seat, the Creafoam kit is the one to use.

X-Large (30 gallons, 60" x 72" bag) is for all drivers in large cockpits with no seat shell. 

Drastically Oversimplified Directions:
Mix the two-part resin (included) and add it to the bag of beads. Place the bag in the seat and have the driver sit against the bag. Pull the air out of the bag with your shop vacuum cleaner or a vacuum pump. After about 35 minutes, the driver can get out. Another 6 - 7 hours later, you have a fully cured seat.
