Bought this for my 4 yr grandson. He was so excited to have his own 'big boy' bed. The assembly didn't take long. Two men put it together in a couple hrs. I had ordered a couple mattresses at the same time so my grandson was able to sleep on it the first night it was assembled. The bed came in great condition & instructions were easy to follow. They opened all the boxes to organize the wood pieces as well as the hardware. Like all bunk beds, they are a little more difficult to make. The full size bed easily holds my grandson & one of his parents. He often asks a parent to sleep with him because with all the room, he can. I would suggest upgrading on the mattresses to a memory foam or gel due to the height size restrictions of the bed sizes. Wayfair sells a variety of mattresses to select from.
