I have asked the shelf next to my washing machine. It stands firmly and securely on the floor (for more details see below), even if the washing machine washes the spin cycle. The setup was very easy and achievable with a person with no problems. The quality of the wood is good and absolutely awesome for the price. The visuals are great :)
Unfortunately, the shelf had wobbled a bit because apparently have feet minimum length differences in my copy. Therefore, I have put a small piece of cardboard under one of the rear legs. Now the shelf is very stable and without any wobbling on the floor.
Since the shelf otherwise completely convinced me and excited, I give 5 stars.
