This bed is AWESOME! I worked on putting this together an hour or 2 about every day for a week. I needed my husbands help a couple times, but mostly built by myself. I should have used him a little more, I would have 1 less dent in the wood, but its really not noticable anyways. This fits a 10 inch mattress (also from Wayfair) with a pillow top mattress pad and some fairly fluffy bedding. I did secure the bed to the wall per the instructions, but I did not attach the bookshelves to the bed frame. The directions were mostly easy to understand, the toughest part for me was mounting to the wall. I needed to run to the hardware store for a tiny screw driver to secure one wood plank to the top, I should have installed under a taller ceiling area. This bed easily transitions from open to closed. Highly recommend!
