The manual is quite correct except for a few points that deserve to be a little more precise. However during assembly, we see that the wood screws holding the 2 trays sabîment and / or foirent in the pre-drilled hole when tightening would have required either through screws or inserts. I realized that the amounts were distorted when we pressed them to adequate torque, there should have been internal braces to stiffen during tightening. Finally the assembly has a small lateral play when laterally handles by the plates. I'll try to do some grounds at the shelves and you should be fine for use as I have. A still recommend for someone who wants to buy a set without breaking the bank and longer manufactured in the EU!
