We LOVE the bunk beds!  We bought the grey ones and love the color.  My wife and I are 68 and we put them together ourselves.  The hex wrench provided was not adequate to put the beds together.  We wee delighted to find slates included because we were informed that they were not.  There were also screws to make sure Te slates did not move.  The only problem with the instructions is that they really do not tell you what to put together in what order.  Once assembled, we discovered the mattresses we purchased were not long enough.  We have purchased plywood to cut to size and put under the mattresses on top of the slates.  This should eliminate any problems with sagging mattresses or dropping pillows.  These beds are really sturdy and well worth the money!
