There is only one reason for only 4 stars instead of 5. For those familiar with Ikea assembly of the shelf is not difficult. Indeed it may be simpler because it not need tools, just the force to insert surfaces in fasteners.
For so I recomend assemble a sort of hammer with a soft surface for typing surfaces in fasteners without leaving traces. The assembly lasted a morning.
A star is less for fasteners. They are made of a hard plastic, in my opinion not very flexible, so it can break if there is too much assembly / disassembly. A casue of this plastic assembly is somewhat laborious, as if the surfaces are pushed fully alignment is not ideal; not bad but not great either.
I recommend it? Of course. At this level of the shelf price is widely suppérieure that IKEA supply (storage suspended in tissue) and when assembled it is solid. Aesthetically other talented people pous concerning art and colors diesnt it's not too bad, so that's good.
