It's nice that it takes just about all of the load off of the body. You can also put a rivet or a bolt through the ends of the tubing and hold the body up to the seat frame. ABS doesn't really ever sag much, though (compared to HDPE...). I also had an ST/295 years ago that had a piece of 1" tubing bolted to the frame right under the middle of the floor pan. it was located just behind the sticks if I remember right, and it was located so that whenever you stepped into the bottom of the machine, the load was on the 1" tube under the floor pan. It eliminated flexing of the pan, and you could stand right up on it and bounce around without risking the pan.
