Procedure; Human Factors
During scheduled maintenance at ZZZ; the 1st class seat row 1FD was found to be unsecured with the forward attachment point sitting on the carpet forward of the seat track. Maintenance personnel at ZZZ while performing scheduled maintenance noticed that the forward attachment point was unsecured.  This was my first time installing passenger seats in the cabin and I believe that the other technician was equally inexperienced on this task. We were reinstalling the seating after a cleaning had been performed due to an overflowing lavatory event. I can only speak for myself; but I thought that the attach points were seated into the floor tracks properly and secured. Technicians should consult a lead or other experienced personal when performing a task that they are unfamiliar with. This is especially true for tasks such as passenger seating where the safety of the flying public is at stake. A computer based training course on passenger seats or asking for a second set of eyes on the work that had been performed could have mitigated this mishap from occurring. In the future I will ask for assistance with unfamiliar tasks.
