The slatted base comes in a very large package and in one piece, so you should premeditate a method of how this gets in the gewüschten room (I had him in through the window wearing). The slatted frame is really stable and the zones fulfill all their purpose and are not only an 'unnecessary feature'. It is very pleasant and there is no need to Umgewöhung it to sleep well.
Furthermore, I must say that I could not notice any noise, which was so criticized in so many reviews here. Free of annoying noise, stable, fit and above all comfortable.
