Value for money,
it has good suspension for the child like a shock absorber so that it is not strained on uneven terrain. 3-point harness and leg straps. We have had it for 2 days and it doesn't bother you at all while riding the bike. If you place it 10 centimeters above the rear rack, it has room to sway. Child weighs 12 kilograms, height 83 cm, currently seems sturdy.
The cushions are just to prevent sitting on the plastic, they are not thick at all.
The height of the legs is adjustable. It was installed at the store where we bought it, so I have no opinion on the difficulty of installation.
