For attachment you need a little patience, a Phillips screwdriver, and must attach properly the washers. This requires some patience, but also works alone without much technical skills.
The board then sit properly fixed, Caution, do not overtighten the screws, as per approved comes loose. My little rabbit fit to second plan or sprawled alone. You can play on time without it begins to rattle.
The workmanship is good and without adhesives etc. Therefore, it is not so bad if it is gnawed.
We are very satisfied and such floor seatboard be happy to buy again if my other example, no longer is good.
