The Treva Twin over Twin Bunk Bed with Trundle is sturdy and attractive.  The trundle pulls out smoothly and my six year old granddaughter climbs the ladder easily.  I chose to pay for assembly for my son's family and he told me he was so glad he didn't have to do it himself because the assemblers seemed to be very familiar with the bunkbed and efficient and careful with their work.  We had some difficulty with delays in the scheduled time for assembly, but Wayfair customer service was extremely understanding and settled the issue in a way that made us feel that our patronage is valued.
