This bed is great.  We got the lighter wood to counter the imposing feeling in our small kids guestroom.  There were very clear instructions and the boxes were well packed with one unit of the bed at at time.  There was no particle board, all solid wood (yes finger jointed) but very sturdy construction.  We got 2 folding memory twin mattresses for the top and trundle bed and a 5" Gel Memory Foam Mattress.  The only suggestion I would make is skip the trundle bed part.  The trundle bed is hard to pull out and push in. It's heavy and the wheels sink into carpet.  We are just folding the mattress in the room as a chair for now. The folding mattress is fine on the floor and the kids don't need the wood frame.  Even adults get very little upgrade by being on the frame 2 or 3 inches off the floor with a wooden side of the bed.
