The seat runners are not flush with floor and bow when bolted down. Chopping off the excess thread of a fixing below that causes this and corresponding relief of carpet and wooden floor below to accomodate remaining nut helps reduce bowing. This followed by a thorough grease of runners should have them moving smoothly.
ETA: I did consider the offset Moto-Lita but the smallest size they do is 14 inch.
