The highchair corresponds (almost) the performances. By the missing tool for assembling here a normal toolbox for building is necessary. The attached manual is spartan and requires technical knowledge or DIY knowledge. The chair built makes a stable impression, however, remains to be seen, we are resilient plastic parts. A supplied defective foot was replaced quickly and easily. Unfortunately, the color (blue ??) do not correspond to the model supplied, so there is the trigger. The adjustment (height / inclination of the seat) and folding mechanism are easy to use, the supplied tray (2 parts) and the tray holder plus power are great in the total price.
