First of all, after you've managed to build, you can sleep on it brilliantly. The simple construction I can not confirm, unfortunately. Only with another tool to let the screws reindrehen in the sunken holes. If you have none, you have the "quality" using hex wrench, which is supplied. This hex wrench, and much cornea on the hands, as the strength of a bear, you can purely turn the screws. After you've made this, a manual comes to light with which one can not do anything really. You have to look on the main page, and guess how many times what color should be used in the rubber submissions now. Furthermore, the great guessing game continues to set the hardness of the slatted frame. Please look at the page. In the meantime, one has again fueled power after the rates to purely push the individual slats in the devices. Here inhuman forces are required. But with a few breaks and sore muscles the next day just to even it. Thanks for the sport active day to the sellers and manufacturers! I am glad that the construction is not complicated!
