I purchased the twin loft with the desk underneath. It is a really nice loft that looks great and is very sturdy. It was not overly difficult to put together. It does come in several boxes, but from start to finish (including getting everything out of the packaging), it took me (a woman in her 40s), with a little bit of assistance from my 13 year old daughter, about 5 hours to complete. The directions could be written a little clearer (i.e. they should specifically note which direction to install some of the pieces in - I ended up having to take a few things apart and turn them around), but again, putting this together was not bad at all. Note that the little side table shown in one of the pictures does not come with the bed, but you can find it for sale online. My daughter really loves the loft.
