Seat occasionally “rocking”?

[Boose]

Are the bolts that fix the seat to the floor nice and tight? I ask this because I had a slight rocking with mine a couple of years ago. My wife had lost her wedding ring down the side of the seat. The only way to get it was to unbolt the seat and lift it up. When I put it back I didn't tighten up the bolts sufficiently. This caused a slight rocking sensation when braking and accelerating. So I went back and re-tightened things and rocking motion hasn't happened since.

Another great point actually... My 05 was a bit lose at first. After tightening them down is when I started messing around with the position adjustment to try and get it tighter.
