Harper & Bright Designs Twin Loft Bed with Slide, Storage, Stairs & Roof - Wooden Kids Loft Bed Frame for Boys & Girls - Perfect for Small Rooms, Playrooms & Sleepovers (Twin Size, White)

First off let me say this is a beautiful bed and my daughter loves it so much!!!Okay so this bed does not take just 40 mins to assemble!I started at 6:00pm and finished at 12:34am and I only stopped once for like 10 mins.The tool that it comes with to screw the nails is not good it wore down after the third nail I had to go buy like three more to find a good one.The mattress size recommended 4-6 is to small I would go with 8.This definitely is atleast a two person job!My son helped me and our hands were hurting so bad after.Besides that stuff the bed turned out beautiful!!!!
