The bookcase didn't take too long, assembly was fairly obvious, but had an extra panel, just a narrow strip of ply, not mentioned in the instructions. I guess who ever packed it couldn't bothered to dispose of it and thought it easier to include it in the package.
The sideboard was rated at a 1 hour job. In fact it took 6 hours and all the bits were not fully resolved until near midnight. The instruction were just the pictogram style, no words to help and it was enormously complex internal frame work, for 5 drawers and 2 cupboards. Lots of bits of wood all different sizes and no way to tell one piece from another, except by guess work. All the parts were given numbers on the drawing, but no numbers on the bits of wood at all. What would it have cost, to just have sticky labels with numbers on, on each of the sections?
I eventually got to the end, after several attempts and much pulling apart and reassembling the correct way - then there was a length of nylon strap left over, with no obvious place where it was needed. It was shown on the pictogram, but gave no clear indication of where it was intended to go or its actual purpose. I looked at several flat pack assembly videos on Youtube, before eventually spotting one which showed the assembly of a wardrobe. That had such a strap between the top of the wardrobe and fixed to the wall, to prevent it falling over.
I really couldn't see this low and deep sideboard managing to fall over no matter what, so I have not bothered to fit it.
SWMBO had ordered both without even mentioning it to me, or discussing it, she just said there would be two big parcels arriving. I was always totally against such flat pack furniture, seeing it as cheap looking, made from fibre board and lacking any style, but these look really - not too bad at all if you like the rugged look.
