Narrative:

One of the flight attendant's discovered the entire row of seats (20-abc) was not attached to the floor properly. She discovered the problem when standing on the aisle seat (20-C) while checking emergency gear in the overhead bin. While standing on seat 20-C; the entire row (20-abc) lifted up from the bulkhead or window side. We could not rock the seat row; but could put weight on the aisle seat and the whole row would lift off the floor. This was discovered by accident and was of great concern; because this aircraft just came out of heavy maintenance check and that row with people could have moved during turbulence. I feel the inspection procedure should include pushing down on the aisle seat as well as rocking; etc; to discover if the row is attached properly. We reported to maintenance control and the seat problem was addressed before departure.
