Nice design to maximise shelving options with limited space, fits the corners very well. Typical flat pack construction, mdf/chipboard with veneer finish.  very quick and easy to assemble, comes with solid wall plugs, not suitable for plasterboard so be prepared to have your own at hand. Other than that all fittings included as well as a drilling diagram to place all fittings in one hit. Although personally I still prefer to rely on a level and tape measure for peace of mind.
