How to Fix a Loose Toilet Seat So It Stays Tight
A toilet seat that slides around every time you sit on it is one of those little jobs that gets put off for months, and it really only takes about 10 minutes once you know where the fixings are and how tight is tight enough. Nearly every loose seat comes down to the 2 hinge bolts at the back, so that's where to start.
Work out which kind of fixing you've got
Lift the little covers on the hinges at the back of the seat. On most seats you'll find a bolt going down through the pan with a nut underneath the rim, which you tighten from below. Some seats are top fix instead, where the bolt screws down into a rubber anchor that expands inside the hole. Those tighten entirely from above, which is a lot kinder on your knees.
Line the seat up before you tighten anything
Sit the seat so it's square on the pan and the front edge lines up with the front of the bowl. It's easy to tighten a seat that's slightly crooked and then wonder why it never feels right, so get it straight first and keep a hand on it while you work.
Tighten it, but not too far
For bolts with a nut underneath, hold the nut still with your fingers or a small spanner and turn the bolt from the top with a screwdriver. The nuts are usually plastic and the pan itself is ceramic, so go a quarter turn at a time and stop as soon as the seat stops moving. Over-tightening is how plastic nuts strip and how a pan gets cracked, and a cracked pan is a much bigger job than a loose seat.
When it keeps working loose
If you've tightened it properly and it's loose again in a week, the fixings are probably worn. The rubber or plastic washers squash and split over time, and a stripped nut never holds however hard you turn it. Replacing the fixings is the fix, and if the seat itself is cracked or the hinges are worn it's often easier to replace the whole seat, because a new one comes with new fixings anyway.
When the bolts won't budge
Metal bolts on an older toilet can rust solid. A squirt of a penetrating spray left for 10 minutes or so often frees them. If it doesn't, the bolt may need cutting off below the hinge with a junior hacksaw, and it's worth going slowly so you don't scratch the pan.

I tighten these a quarter turn at a time and check, because a plastic nut gives no warning at all before it lets go.
