Once placed all racks and modules in the correct order on the ground, looking at the color photo and gradually assembled by piece by piece, you could not go wrong.
I do not know how long it lasted, but without hesitation or to taste around, I screwed the slatted frame together. The screw holes fit, did not have to be reamed, and the modules could have only one right place. Very relief are the different color codes. Afterwards, I was very proud of me - 64, women - that I did not have to get my neighbors to help, in which I had already "signed" me.
After the 1st night my back was the morning said that I chose well.
From me - to once a night - a total purchase recommendation.
