Light internal door
You want a bedroom or kitchen door that is not a fire door to stop drifting, and you do not need two hydraulic valves. The Offfay roller-arm spring is the best value at about £8.50, stated for about 20–25 kg, with 4.4 from 532 reviews and no fire-door claim. Springs in this band weaken, and they will not damp the latch.
