A quick solution was needed. In the other reviews I had read that the grid that is attached to the respective inner straps of the head restraint, it requires that both seats have identical position and tilt angle. That's not a problem because I'm the only female driver and almost always "only" the dog on board have for me. That the grid would provide with its mounting space for proper motion, it was clear from the outset.
The assembly instructions are really a joke - you can ignore them completely, the assembly is quite logical indeed. When you set up in the vehicle, I found it very convenient that my husband could set the vertical bars on site that required a bit of force. It is also easier to grip the structure for two and bolted.
The three cross-members can be pulled out so far that even my smallest 25cm Fiffi not get away right and left. The distance of the three elements on the vertical struts can be individually set and then fixed with Spax screws. Even with the slightly higher SUF yes I find the existing elements are adequate.
The first trips "with" are behind us and I am very glad that the grid is installed and is doing its job, I would buy again at any time.
A star, I prefer from - because the construction is also screwed yet wobbly because it is fixed only with clamps on the headrests and the instructions for use does not deserve the name. However, just the attachment to the headrests have been a reason to buy for me because it has nothing in the car are bolted, the vehicle remains intact.
