Assembly took me about two hours.  You have to predrill holes which is tricky as you need an extra long bit.  I found that the base was too big and had to plane off about  4 mm to get it to fit.  As other purchasers have said it needs to be finished if you don't want bare softwood exposed.  I used grey ducks back, which looks good.  Overall fairly pleased with it.  No liner supplied so,will have to fashion some from polythene or bubble wrap.
