The structure has been relatively easy to accomplish. The parts were processed properly for the price and have fit well together. The extra bed is good and stable next to our bed and does not wobble.
Only the plastic rollers convey no impression stable, therefore also a star deduction (although you could also build it well without the wheels, as the lying surface can be infinitely adjusted in height).
We would buy the extra bed definitely be back and are also confident to use it later as a bank on.
